Toyota Motor Corporation is a world famous automotive corporation. It was founded as an independent company in 1937. Along with the production of cars that have proven themselves in the global car market, the concern pays great attention to the development and production of modern . The company began manufacturing the first power units for its cars in 1939 and has since produced a huge number of a wide variety of engines. Among the most famous of them is the 1ZZ engine, which for 19 years (1998-2007) was produced in three versions:

Description

Any 1ZZ engine is an in-line four-cylinder power unit, the cylinder block of which is made of aluminum alloy.

Thin-walled cast iron cylinder liners are fused into the material of the main block. The outer walls of the sleeves have structural elements that contribute to their strong adhesion to the base.

The cylinder head of the 1ZZ FE engine is made of aluminum alloy. The gas distribution mechanism is a 16-valve DONC.

Structurally, the engine block of this series differs from the rest:

• open top cooling jacket. This made it possible to significantly improve manufacturability. At the same time, the strength of the block slightly decreased;
• a massive light-alloy crankcase, which is integral with steel main bearing caps. The split line between the crankcase and the cylinder block runs along the axis of the crankshaft, which increases the rigidity of the cylinder block and somewhat compensates for the loss of strength caused by the presence of an open cooling jacket.

The 1ZZ FE engine is a long-stroke engine with a piston stroke larger than the cylinder diameter. This solution made it possible to improve traction at low speeds and reduce heat loss through the walls of the combustion chamber, the volume of which is reduced.

The design of the valve seats is also of interest. In their manufacture, laser deposition technology was used, which made it possible not only to reduce the thickness of the seat, but also to improve the cooling of the valves.

The valves are adjusted using adjusting pushers of different thicknesses, the cups of which simultaneously act as a pusher and a washer. The gas distribution mechanism is driven by a single-row roller chain.

The drive mechanism includes:

• remote hydraulic tensioner with ratchet mechanism and preload spring;
• special nozzle for lubrication;
• tensioner shoe;
• sedative.

Maintenance

The requirements for the maintenance of Toyota engines of those years of production are almost the same and boil down mainly to the timely implementation of such procedures as:

1. engine oil change every 10,000, and preferably after 5,000 km of run.
2. adjusting the valve clearances of the gas distribution mechanism every 20,000 km.
3. replacement of the timing chain drive every 150 ... 200 thousand km.

This fully applies to the 1ZZ EF engine, which belongs to the category of so-called "disposable" power units. A major overhaul of these motors is impossible in principle, since the manufacturer does not provide for re-sleeving of cylinder liners. This also applies to the crankshaft bearings.

Faults

The 1ZZ EF engine is quite well known to domestic motorists. Therefore, its weaknesses are also well studied. The most common faults are listed in the table.

DEFECTS	THE REASONS	HOW TO FIX
Noise and knock in the engine 1zz fe.	The timing chain has stretched - it may appear after 150 thousand kilometers.	1. Replace the chain. 2. Check and, if necessary, replace the chain tensioner and guide.
The 1zz fe engine is unstable (revs fluctuate).	Clogged: 1. Idle valve. 2. Throttle valve block.	Flush clogged nodes.
High consumption of engine oil.	Wear of oil scraper rings.	1. Change the oil scraper rings to new ones manufactured after 2005. 2. Bring the volume of engine oil to 4.2 liters. Note: decarbonization of rings does not eliminate the defect.
Strong motor vibration. (a characteristic feature of the motor).	The rear engine mount may fail.	Check and, if necessary, replace the rear mounting pad.

tuning

There are several ways to increase the power of the 1ZZ FE engine:

• The most effective way to increase power is to install a Toyota SC14 compressor.

In addition to the compressor, an intercooler is installed on the motor to cool the charge air; Blow-off valve to bleed air when the throttle is suddenly closed; nozzles 440 cc; fuel pump Walbro 255 lph. By properly adjusting the technical characteristics of the motor using Greddy E-manage Ultimate, you can squeeze out of it (without modifying the standard cylinder-piston group) a power of about 200 hp. With.

• There is also a way to increase the power of the 1ZZ FE engine to 300 or more hp. With.

To do this, you need to: purchase and install on the engine a turbo kit with a Garrett GT284 turbine (intercooler, blow-off, etc.); Ÿ nozzles 550/630 cc; Ÿ fuel pump Walbro 255 lph; Ÿ forged connecting rods; Ÿ pistons for a compression ratio of 8, 5;Ÿ organize the exhaust on a 2.5-inch pipe;Ÿ replace the standard control unit of the power unit with Apexi Power FC.

• If the owner of a Japanese car needs to slightly increase the power of the 1ZZ FE engine (no more than 30 hp), then it will be enough for him: Ÿ change the standard camshafts to Monkey Wrench Racing Stage 2 (phase 272, rise 10 mm); Ÿ organize a direct-flow exhaust with spider 4-2-1;Ÿ ensure cold air supply.

The 1ZZ engine is the most common today. Literally every day more and more cars with these power units are imported into our country. The problem is that in Russia they are not sufficiently studied. There is very little information on them. Let's try to systematize what we have.

Short story

The first Toyota 1ZZ engines began to be produced in 1998. They were manufactured until December 2007. The first unit was developed in Canada. And they were industrially produced in Cambridge, in southern Ontario.

Almost immediately, the engine proved to be excellent and was used mainly on cars for domestic sales. These motors were put on huge quantities of C- and D-class cars, and in series.

Speaking formally, it was supposed to replace the 7A-FW of the previous generation. ZZ-engines were noticeably better in terms of power, and were also not inferior in terms of efficiency. But since these motors were installed mainly on top models, they actually replaced the 3S-FE, not too inferior to them.

Characteristics

The engine cylinders had a diameter of 79 mm. The piston went 91.5 mm. The volume of the unit was 1.8 liters. Power was different - from 120 liters. With. up to 140. The cylinder block was made of die-cast aluminum. The cylinders were made of cast iron in the form of sleeves.

The 1ZZ engine used a multi-point injection system. The gas distribution path provided high fuel economy at low revs. This unit also had excellent traction at high speeds. Design features include forged connecting rods, a fully cast crankshaft, and a plastic intake manifold.

In our country, these units are familiar to many as Toyota engines. They were equipped with Toyota Corolla, Celica, Allex and other models. Let's consider their design in more detail.

Cylinders and pistons

An aluminum cast cylinder block, cast using technologies unique at that time, became the Japanese manufacturer's second experience in creating engines from light alloys. The new Toyota engines were different. This is a shirt open at the top for circulation of the coolant, which is not reflected very well in the rigidity of the entire structure.

Among the advantages of such a scheme, weight reduction can be noted. So, the unit in the new modification has a weight of 100 kg, while the previous model weighed 130. The main thing is the ability to produce a cylinder block in a mold. Traditionally, when the blocks were made with closed jackets, the units were tougher and more reliable, but the process was more difficult, and the technology more expensive. Sometimes the mixture could collapse.

Another feature is the crankcase. It combines the crankshaft bearings. The split line of the crankcase and block runs just along the line of the crankshaft axis. The crankcase, also made of light alloy, is made in one piece with steel caps for the main bearings. It also increases the rigidity of the cylinder block.

ZZ-motors can be attributed to long-stroke motors. The characteristics of the stroke and diameter of the cylinders allow to obtain improved traction characteristics. This is a more important parameter for mass models than high power at high speeds. In addition, fuel economy is also good.

During the design work on the engine, the developers were dominated by the idea to reduce friction and make the system as compact as possible. This was also reflected in the reduced diameters of the crankshaft journals. But the load on them increased, and, as a result, wear increased.

You can select a piston. It has a shape that is close to diesel. To reduce friction with a large stroke, the designers reduced the piston skirt. This was reflected not in the best way on cooling. The T-piston on new machines starts knocking very early. In classical models, such a drawback appears much later.

It is believed that these engines have a disadvantage. Many people believe that repairing the 1ZZ FE engine is impossible. But this is not true. It is quite possible to repair them. Yes, they had problems. At first, there was an increased "appetite" for waste. It was caused by rapid wear and the occurrence of piston rings. It is possible to "treat", but if the sleeve is worn out, then the 1ZZ contract engine serves as the way out.

Correction of problems in 2001

And this is not all true. After this unsuccessful year, the models of the ZZ series units were equipped with modified rings. In the same year, the cylinder block underwent changes. This did not particularly affect the previously released models, but it was possible to put rings. However, the problem has not gone away. And today there are many cases when, because of this problem, people put a contract engine even on new cars of 2005 with low mileage.

cylinder head

The head is also made of light alloys. Conical combustion chambers. Here, the combustible mixture goes to the center and forms a kind of whirlwind near the candle. This contributes to the rapid, and most importantly - complete burnout sweep.

The 1ZZ engine has a compression ratio of 10:1. But the unit works fine on 92-octane gasoline. The Japanese argue that even the best gasoline will not lead to any increase in performance. Other models have a higher compression ratio, they need better gasoline.

Light alloy seats are used instead of traditional steel valve seats. They are made using unique technologies and are four times thinner than usual, which has a great effect on cooling.

The gas distribution mechanism is a familiar 16-valve system. Earlier variants had fixed phases.

The Japanese reduced the weight of the valve. This greatly reduced the impact on the valve springs. Here again you can see the minimization of friction losses as well as increased wear. For some reason, Japanese engineers decided to abandon the adjustment of valve clearances with washers. Now there are adjusting pushers in the motors.

The timing drive has changed radically. Now a chain with a pitch of 8 mm is used there. This can be called an advantage, but the chain requires frequent replacements. And her shortcomings are quite significant. The chain requires a hydraulic tensioner, and these are increased requirements for oil. Japanese devices are not very high quality, and the chain tends to stretch.

Inlet and outlet tracts

The intake manifold is now in front. Graduation is located on the opposite side. This step was taken due to environmental friendliness. It was necessary to make the catalyst quick-heating. However, they did not fix it behind the exhaust manifold, the release was placed in the back. The catalyst is under the bottom.

The intake tract is quite long. It allowed to significantly increase the return at low and medium speeds. Instead of the already traditional 4-pipe manifold, ZZ-engines got a spider with aluminum air ducts.

However, Japanese engineers later came to the conclusion that metal can be replaced with plastic.

Fuel system

Here, too, compared with previous versions, there have been changes. In order to reduce evaporation in the fuel lines, experts did not use a vacuum regulator circuit. Here, a pressure regulator is used in a submersible pump. Installed new nozzles with a large number of holes. And they are mounted in the cylinder head.

What happened

As a result, we can say that the engineers made a fairly good motor. It is powerful, economical, has good opportunities for modernization. However, owners are more interested in how the units behave after a significant run, how to repair the 1ZZ engine. Alternative motor no longer exists.

Lubrication question

According to the instructions for the motor, the Japanese are advised to fill in only 5W30. There are special oils manufactured by Toyota. These are synthetic lubricants with a viscosity of 5W30. But there are no specific recommendations.

Many do not know which oil is best for a 1ZZ engine. There is an original Japanese synthetic. But some prefer other options. Someone recognizes both 0W-20 and 10W-30 as normal, and this is not considered something criminal.

Opinions about the motor

You can't find any reviews on the Internet. Many complain about the increased oil consumption. Most owners believe that the unit is too picky about our fuel. Repair is a simple replacement of the 1ZZ engine.

Many note that after 170,000 km, the cylinders look great, the heads are in good condition. They also write that subsequently there are no problems with them. But that's how lucky.

The problem with oil consumption was solved in 2005, and now no one is faced with this. Basically, the problem motor is a contract engine from Europe from 2002.

After 2005, you can freely pour oil into the engine, and it will consume it as usual.

Even the owners sometimes encounter noise. Often this problem is solved by replacing the chain. Valves practically do not knock.

There is also such a moment: floating revolutions. This issue can be solved by flushing the throttle body. If you encounter vibrations, then you should check the rear motor mounts. If it doesn’t help, then it remains only to put up with this problem.

As noted by the existing reviews about the 1ZZ engine, the motor must not be overheated. It is believed that in this way it is possible to melt or deform the cylinder head.

According to the Japanese, these units are not subject to repair. Some services may offer cylinder liner or bore. But officially no one is engaged in the repair of these motors.

It is also worth saying that the resource of the unit is small. It is only 200 thousand km. But after 2005 the problem was solved. And it turned out to be quite economical, just for urban conditions, the 1ZZ engine. Reviews about him are proof of this.

For example, the owners of Cellica with this motor believe that the unit lacks dynamics. Consumption is about 7 liters per 100 km. The engine is picky about fuel. If we consider oil consumption, then this figure is at the level before 2005, and therefore we have to face such a problem. The issue is solved by smearing the crankcase gasket with sealant. But this is not for long.

Price

The fact is that these units are delivered straight from Europe, after European drivers ride on them. They are imported into our country by special suppliers.

In different companies for a 1ZZ engine, the price can vary significantly. On average, prices are kept at about 50,000 - 60,000 rubles. But this is a Japanese quality, which, in spite of everything, allows you to successfully move on our roads on fuel that is not always of high quality.

So, we found out what features the 1ZZ engine has.

The line of Toyota engines under the ZZ marking contains two 1.8-liter units. The 2ZZ modification is adapted for high revs, so the 82 mm engine has a cylinder with a piston stroke of 85 mm. This made it possible to increase the power to 192 hp. With.

Conversely, the ICE variant 1ZZ FE produces maximum torque at medium speeds. To do this, the cylinder diameter is reduced - 79 mm, but the piston stroke is increased - 91.5 mm. In this version, the manufacturer provides for economical fuel consumption and Euro-4 environmental standards.

For the conveyor production of 1ZZ-FE engines, management used the facilities of the TMMC plant in Cambridge (Ontario, Canada). Then the manufacturer had two more versions, the first 1ZZ FED was produced at the Shimoyama plant inside Japan. The second modification 1ZZ FBE was assembled in Brazil, used Ethanol E100 biofuel, mounted only on Toyota Corolla for the domestic market of this country.

Specifications 1ZZ FE 1.8 l / 120 - 143 l. With.

The main feature of the Toyota ZZ family of engines is an aluminum cylinder liner inside an aluminum block. The in-line DOHC V16 gas distribution engine is supplemented with a phase distribution fluid coupling on the intake camshaft and a dual and then individual DIS-2 / DIS-4 ignition system, respectively.

For Toyota Vibe, Corolla, Matrix models, a TRD supercharger was available for two years (2003 and 2004). The chain drive is used to increase the resource of the timing drive, pushes back the overhaul by at least 150 thousand mileage. The 1ZZ series has the largest volumes of tent-type combustion chambers.

The absence of hydraulic compensators in the design, on the one hand, reduced the requirements for oil quality, on the other hand, added do-it-yourself adjustment of thermal valve clearances every 30,000 km.

Design features

Japanese and North American developers have incorporated the following design features into the 1ZZ FE engine:

• cylinder head cover - made of an alloy of magnesium and aluminum, mounted on an acrylic gasket;
• cylinder head - inlet channels are vertical, coolant channels are located near the inlet;
• cylinder block - a block of bearing caps is one-piece, some parts are cast in the body;
• piston - with a displacer at the end, no size groups;
• connecting rod - forged from a vanadium alloy;
• crankshaft - 8 counterweights, 5 supports, cast iron;
• Timing - pushers 35 standard sizes instead of washers for adjusting thermal gaps, driven by a multi-row roller chain with an 8 mm link;
• VVTi mechanism - only on the intake camshaft.

The manufacturer has developed a special SLLC Toyota Genuine coolant with a high service life of 80,000 km.

List of engine modifications

In addition to the basic version of the 1ZZ-FE engine, two modifications were created:

• 1ZZ FED - made in Japan (Shimoyama), has a torque of 171 Nm in a high rev range, a power of 140 hp. With.;
• 1ZZ FBE - Brazilian version specifically for biofuel E100 Ethanol.

In addition, the motors differed in performance due to the ECU firmware:

• in 1998, parameters of 171 Nm and 130 hp were used. With.;
• since 2000, forcing up to 136 liters has been made. With.;
• at the same time, a derated power drive of 129 liters was produced. With.;
• since 2003, torque has been clamped to 161 Nm, and power has dropped to 125 hp. With.;
• modernization in 2004 again increased the performance of the internal combustion engine 171 Nm and 140 hp. With.

In the last year of production - 2007, the torque remained the same 170 Nm, and the power decreased to 132 hp. With. For all the years of production, attachments have not been modified.

Pros and cons

The motor bends the valve during a sudden open circuit or link jump. Despite the high thermal conductivity of aluminum, the block is prone to overheating. The geometry of the structure is distorted, jamming of pistons or valves is possible.

On the other hand, the motor is highly resourceful, until the full development of the ShPG block, the crankshaft, timing and other components remain maintainable. The problem with the "oil burner" disappeared after the revision in 2005 of the design of the oil scraper rings.

List of car models in which it was installed

The base atmospheric engine 1ZZ FE was developed for the following Toyota passenger models:

• Wish - five-door minivan;
• Allion - youth sports sedan;
• Isis - seven-seater minivan;
• Corolla CE / S / Le / VE / Fielder / Runx - for the Japanese market;
• Corolla Altis - for the Asian market;
• Opa - crossover / station wagon all-wheel drive;
• Premio - large class D sedan;
• Avensis - sedan, liftback and hatchback;
• Caldina - front-wheel drive station wagon;
• Matrix XR - front-wheel drive hatchback with crossover design;
• RAV4 - all-wheel drive crossover;
• Celica GT - all-wheel drive convertible, liftback and hatchback;
• Vista - hardtop for the Japanese domestic market;
• MR2 - two-seater sports version;
• WiLL VS is a combination of a sports station wagon and a hatchback.

Engine characteristics for cars from two more manufacturers turned out to be suitable:

• Pontiac Vibe - station wagon with hatchback features;
• Chevrolet Prizm is a classic sedan and hatchback.

The 1ZZ FED modification was equipped with Toyota Will VS, Wish, MR2 Spyder, Celica GT and Corolla cars. The Brazilian motor is exclusively on Toyota Corollas and only in this state.

Service schedule 1ZZ FE 1.8 l / 120 - 143 l. With.

For the convenience of the owner, the original manual provides a description of the parameters that the 1ZZ FE engine initially possesses and the frequency of replacement of consumables / parts:

• the developer recommends inspecting the timing belt constantly, changing it at the turn of 90,000 mileage;
• belts that spin attachments must be replaced after 40 - 50 thousand km;
• filling in new antifreeze and engine oil is recommended by experts after 30 and 7.5 thousand km, respectively;
• the crankcase ventilation system is purged after 25,000 runs;
• the air filter cartridge becomes unusable after 1 year / 15,000 km;
• change the fuel filter after 30,000 miles.

Despite the reliable and simple device of the internal combustion engine, the exhaust manifold is operated in extreme temperature conditions, which means that it can burn out after 50-60 thousand km.

Overview of faults and how to fix them

The atmospheric gasoline in-line aluminum engine 1ZZ FE has the following design defects:

Since 2005, the design of oil scraper rings has been improved, therefore, with a high lubricant consumption on engines manufactured before this period, it is enough to change the rings to solve the problem.

Motor tuning options

The developers of the 1ZZ FE engine have a potential of about 50 hp. With. To increase power, atmospheric tuning is used:

• dismantling of the collector;
• installation of direct-flow exhaust and spider;
• use of a camshaft with 10 mm cam lift and 272 phases, for example, Monkey Wrench Racing Stage;

Another option is turbo tuning to get 200 hp. With.:

• use of nozzles 440ss;
• installation of the pump Walbro 255;
• installation of a bypass Blow-Off valve;
• application of the Garrett GT turbine.

When using supercharging, the tuning is completed by flashing the ECU software version, in this case Apexi Power FC. Pressure above 0.5 bar in the turbine is detrimental to the overall service life of the internal combustion engine.

Thus, the 1ZZ-FE motor has a classic atmospheric-type inline-four architecture, but in an aluminum block with duralumin cylinder liners. That is, in fact, a one-time unit provides a maximum of 350,000 km of run, a power of 143 hp. With. and a torque of 171 Nm.

Modern powertrains from Toyota Corporation seem to be quite reliable and of high quality. These are resource engines with a good design, light cylinder blocks, a well-thought-out supercharger system. Both diesel and gasoline engines deserve some attention from the buyer. But in the history of the corporation, not everything was so pure and perfect. You can remember the times when Toyota engines were not the most optimal. Unfortunately, without understanding this situation, many potential owners buy used cars with these failed units and do not know what problems await them in the future. Today we will talk about the ZZ engine line, which appeared in the corporation's lineup in 1998 and took its place under the hood of the most popular models. In the history of the corporation there were several generations, as well as a number of modifications of this unit. But all power plants with the ZZ index turned out to be similar to each other in terms of shortcomings and potential problems in operation.

In the production of the line, specialists set as their goal lightening the engine, reducing its toxic emissions, and reducing fuel consumption. But the developers forgot about the resource and reliability. Therefore, the main problem of ZZ is the durability of the work. Many buyers already by 150,000 km begin to face serious problems and cannot combine their appearance with the overall reliability of the Toyota brand and its equipment. Special problems for buyers from the secondary market, who cannot even accurately assess the real mileage and the need for service. Today we will talk about the characteristics, pros and cons, as well as some specific features of the motors in this line. By the way, in the lineup they were designed to replace the most successful, but outdated series A, which raised the expectations of buyers.

The base engine 1ZZ-FE and its main troubles

The 1ZZ-FE engine was the first to appear in 1998. This is a simple inline four with 16 valves and a 1.8-liter displacement. The power unit received an aluminum cylinder block, an aluminum cylinder head, as well as a timing chain. Forged connecting rods facilitated the design, VVT-i was called to adjust the valve timing. The volume was achieved by a long stroke of the pistons, and this creates certain nuances in operation. The main disadvantages of 1ZZ-FE are as follows:

• the aluminum cylinder block does not allow for major repairs; after a serious breakdown, the power unit will simply have to be sent for recycling and will buy a new one;
• maslozhor - due to the not very successful design of oil scraper rings, this engine constantly requires the addition of oil in the crankcase, and this adds up to a pretty penny for the owner;
• chain stretching and constant noise under the hood, knocking and metallic ringing, which cannot be solved even by replacing the chain tensioner or completely replacing the assembly (it only solves for a while);
• vibration at idle is just a feature of this unit, which is extremely unpleasant for the car owner, you can try replacing the rear motor mount;
• the throttle and idle valve constantly require cleaning, this is an extremely unsuccessful unit for this power unit in the conditions of Russian unpredictable fuel quality.

The basic version of the 1ZZ-FE produced 120 horses, then the power was increased to 140, which is quite good with such a volume. There were several modifications, but they were precisely of a local nature. One version was prepared for biofuels, the second was further facilitated for installation on small cars. The production of this motor continued until 2007, and this is depressing, since so many popular cars received this engine.

Pros and applicability of 1ZZ-FE from Toyota

The engine was installed both on domestic Japanese cars and on vehicles for the whole world. In Russia, the engine was also actively sold on the Corolla. The main Toyota models with this engine under the hood are as follows: Corolla, Avensis, Caldina, Vista, Premio, Celica and Matrix R. There are more than a dozen models for the Japanese domestic market, which also enter Russia through Vladivostok. But the unit has not only solid disadvantages, you can also find a number of advantages:

• lightness of design creates versatility and the ability to use in almost any car, and high power complements this feature of versatility;
• the design is quite simple, so maintenance is often carried out on their own, you need to pour good liquids and not miss the deadlines, it is also worth inspecting the chain;
• there are not so many minor malfunctions, up to its resource of 200,000 km, the power plant does not spoil the mood of the owner, except perhaps showing some details of its character and design specifics;
• fuel consumption on the Corolla in urban conditions reaches 8 liters per 100 km, this is a fairly economical unit that will save a lot of money on gasoline for your budget for its resource;
• the electronics are thought out and assembled well, there are no problems with sensors and automatic systems, the unit is reasonably built and tuned at the factory, no chip tuning is required.

We talk so much about the 1ZZ-FE for the reason that this is the most massive engine in the line. It was he who announced the new design, and all other modifications simply took it as a basis. This is not to say that this is the worst creation in the history of Toyota, the motor has its advantages. But when buying a used one, you never know when you will have to throw this unit into a landfill and look for an alternative to it. Most often they buy the same contract motor and kill it again until the end of the resource.

What other engines are in the ZZ lineup?

The Japanese do not develop a motor for each model separately. They apply one development to dozens of variations and get excellent results. So the 1ZZ-FE engine received several major modifications for use in different situations. All motors of the family have common problems, as well as common advantages. Only the characteristics and scope differ. In total, the Japanese introduced three additional modifications of the unit:

1. 2ZZ-GE. The unit with the same volume was released in 1999 and received from 164 to 260 horsepower. Such indicators were achieved by installing a turbocharger. The piston stroke was reduced, and the cylinder diameter was increased. The compressor had a good effect on power, but it was somewhat reduced without the best resource. They put the unit on Corolla, Celica, Matrix, MR2 and other models.
2. 3ZZ-FE. Reduced in volume version of the engine by 1.6 liters. The reduction occurred by reducing the stroke length of the pistons. Power was reduced to 109 horses. Accordingly, the design of the cylinder head has changed, but all the shortcomings have remained in place. The engine still could not drive more than 200,000 km. Installed this version on Corolla and Avensis.
3. 4ZZ-FE. It is also a naturally aspirated version, which has been further shortened piston stroke and made a displacement of 1.4 liters. Power also dropped to 97 horses. It was not possible to reduce the consumption, and this erased the understanding of the meaning of such a development from Japanese engineers. In addition to the main disadvantages came the weakness of the power unit and the need to turn it to high speeds. We put the motor on Corolla, Auris and RunX.

Each engine had its own line of modifications, but until 2007 they did not correct the main shortcomings. A small resource, a rattling chain and not the most outstanding reliability of the fuel system spoiled the impression of the engine. In 2007, this line was replaced by ZR, in which some of the problems were corrected and the design of the main problem nodes was somewhat changed. It took Toyota 8 years to understand that the most massive engine was far from being the most successful.

Should I buy a Corolla with a ZZ engine?

If today you have decided to take a car with such a power unit under the hood, then it will be a used car. The car is at least 11 years old, since the units were no longer produced in 2007. This means that the average mileage of such cars will be from 150,000 km. Of course, this is not the best solution, since you do not know the history of the car and cannot guess what real mileage it has passed. Most likely, after the purchase, you will need to invest a lot of money in engine repairs. The disadvantages in this case are as follows:

• there are a lot of cars with twisted mileage on the Russian market, resellers and sites are well aware of the problems of ZZ engines, so they do everything possible for sale;
• motors are not always well serviced, oils and filters are cheap, gasoline from the first oncoming refueling, and for this engine, such an operating option is fatal from the very beginning;
• there are contract engines, but their cost in a more or less normal state starts from 70-80 thousand rubles, this is a lot of money, so you should not hope to replace the engine;
• spare parts are incredibly expensive, and in-depth repairs do not make much sense, this motor is not subject to capital, at most you can repair the block head after minor breakdowns;
• complete with the engine, you will also receive problematic attachments, the generator works fine, but the starter is not reliable on all cars, it may need to be repaired or replaced.

As you can see, there are enough problems in used ZZ. Among the shortcomings, you can also find the unpredictability of the resource of used power plants. Even when buying a good contract motor from Japan, you take risks. Therefore, many car owners go out by swapping this unit to another model. For example, they install a more modern ZR or classic 4A. But such manipulations also require large investments.

We offer you to watch a video explaining some of the properties of ZZ engines:

Summing up

It is generally accepted that Toyota engines are among the best in the automotive market. But this does not apply to the ZZ line, which turned out to be the worst among its rivals from other concerns. There are some advantages in this generation, such as efficiency and quite sane environmental safety. But lightweight cylinder blocks and a successful design of electronic systems do not compensate for a very small resource, constant vibration, noise from the circuit and other troubles. So before buying a car with such an engine, you should seriously think about the possible consequences.

Also pay attention to the quality of engine maintenance. If the wrong oil is poured into it, then the lubricant consumption will be incredible, and the resource will be reduced even more. Gasoline should be poured at one gas station and not choose the cheapest options for this. You can pour 98 fuel, but this will not lead to an increase in resource or a significant reduction in consumption. In general, the motor has its advantages, but there are also a number of disadvantages that should be considered when buying. If you are going to buy a used car with this unit, be sure to check its mileage on computer diagnostics. Have you ever come across this ZZ series engine?

Petrol engine 1ZZ-FE with electronic fuel injection (AI-95) has a volume of 1.8 liters, was originally developed for Toyota Corolla. Produced from 1998 to 2007. The modification of the engine has five different models differing in power and torque.

Weak points of the 1ZZ-FE engine

• Cylinder block;
• Cylinder head.

Weak spots more 1ZZ-FE engine in detail…

Cylinder block

The cylinder block, to reduce costs and facilitate production, has an open cooling jacket, respectively, this has led to a decrease in the rigidity of its design.

Cylinder-piston group

At engine 1ZZ-FE, due to a decrease in the diameter and length of the crankshaft journals, their loading and wear increased. The oil must be changed early, otherwise coking of the piston rings is inevitable. The rings are T-shaped, maybe that's why they start knocking earlier.

cylinder head

You can forget about replacing seats, valves due to the disposable design of the head. Adjusting the thermal clearances in the valves will also fail, except at official dealers. Valve adjustment is possible only by precise selection of tappet sizes to ensure clearance. Most car owners, when identifying problems with the head, instead of adjusting the valves at the dealer, sell their car.

Disadvantages of the 1ZZ-FE engine

• Engine with repair problem;
• Increased oil consumption.

Flaws motor 1ZZ-FE in detail…

Engine with repair problem

A little something will happen to the piston and rings at official dealers on warranty cars, they change the block. It's all about the design motor designed for a resource without major repairs. There is no overhaul in the life cycle of an engine. That is, the sleeves do not bore. For this reason, parts with repair dimensions may not be asked from official engine dealers. I did not say that repair is impossible, it can be repaired by replacing it with new parts and assembly units. For example, a crankshaft assembly, a cylinder block with piston assemblies that are sized according to the drawings for newly manufactured engines.

Increased oil consumption

The disadvantage is caused by the design feature of the motor and the quality of domestic gasoline. The reason for the increased consumption is the occurrence of oil scraper rings, dilution of the oil in the crankcase by gasoline.

Choosing a car is never easy. Do not rush to buy a car, first study the performance characteristics of the engine, its features, disadvantages and weaknesses. The first step is to take into account the spent part of the engine resource. For the 1ZZ-FE engine, the built-in uptime of the engine is approximately 200 thousand km, after which the timing chain and rings are changed with new ones (according to reviews), after which the engine runs quietly up to 500 thousand km.

P.S. Dear Toyota owners with 1ZZ-FE engine! I ask you to write about your practical conclusions when operating machines with this engine.
