Most often, car enthusiasts, when choosing their first car, pay attention to the quality of the interior, equipment, various additional options, designed to give travel maximum comfort. One of the most important parameters of the reliability and durability of a car - engine life, as a rule, remains unnoticed. The Chevrolet Lacetti engine is different high quality and a long service life, but provided that all vehicle maintenance work is carried out on time.
But, still, what is a motor’s resource? Why is it so important to consider when choosing a car?
What determines the operating time of the power unit?
Various encyclopedias, car reference books they say that motor resource is a term that determines the duration of work power plant until the first overhaul. Resource measures time most efficient work unit. The following factors indicate that the motor resource has completely exhausted itself:
- A sharp increase in indicators;
- There is a significant reduction in car power;
- The appearance of various extraneous sounds while the car is operating;
- Increased engine oil consumption.
All these problems indicate that it is time for a major overhaul. For duration stable operation A car is significantly influenced by the volume of the combustion chamber. The higher the volume, the longer the service life. Last but not least, the condition of the pistons and cylinders must be taken into account. Carbon deposits and dust destroy the rings and wear out the upper part of the cylinders.
The Chevrolet Lacetti was equipped with three different engines: 1.4 liters with 94 hp, 1.6 liters with 106 hp, and 1.8 liters with 121 hp. All three engines are related to Opel power units. They also inherited increased oiling with a mileage of 150 thousand. But in general, all three Chevrolet Lacetti engines are different high-quality assembly and therefore large resource. According to owner reviews Chevrolet Lacetti we can conclude that the 1.8-liter engine runs the longest.
Chevrolet Lacetti power units are sensitive to fuel quality. The first problems may appear after the first 100 thousand have been passed. This often happens due to a breakdown oxygen sensor or malfunctions throttle assembly. The first serious work is carried out after 60 thousand of the distance traveled - the service life of the timing belt drive. When replacing the belt, it is best to install a new pump, since it rarely survives to 100 thousand mileage. And if you take into account the fact that the timing belt needs to be changed periodically, it is easy to conclude that the pump will not survive until the second replacement of the timing belt, therefore, in order to avoid unnecessary hassle, it is best to carry out all the work at once.
Problems with increased consumption fuel can appear at any time, despite the fact that the mileage is short and the resource has not yet been used up. The phenomenon is rare and not widespread, however, cases have been observed when the engine unreasonably increases its “appetite”, and full diagnostics does not detect any problems. Owners of Chevrolet Lacetti also report that on engines 1.4, 1.6, after 80 thousand km, the fuel pump begins to hum. If the pressure sensor fails, interruptions in engine operation may occur. Also in this mileage range, during operation of the 1.8-liter Lacetti engine, extraneous sounds, often associated with the operation of the hydraulic compensator. Often there is a knocking sound in the intake manifold.
How to increase the service life of the motor?
The service life of a Chevrolet Lacetti engine largely depends on the quality of service and operating conditions. Chevrolet Lacetti owners leave various messages about service life power unit. One driver has a resource of 300 thousand km, and the other has 200 thousand km. But there are cases when the Lacetti engine requires major repairs even after 150 thousand km of travel. Why is this happening? What should you do to keep your car on the road for as long as possible?
It is necessary to monitor the oil level. Quality - main criterion. It is the oil that determines how long and trouble-free the “heart” of the car, all components and assemblies as a whole, will work. The oil must be selected taking into account the tolerance specified by the manufacturer in the operating instructions.
It is enough to carry out minor repairs on time, monitor the condition of the spark plugs, and periodically measure engine compression. This is quite enough to ensure that the Chevrolet Lacetti engine lasts as long as possible, having completely exhausted its service life.
Engine Chevrolet Lacetti 1.6 liters with a power of 109 hp. turned out to be the most popular Russian market. The naturally aspirated petrol engine has the factory designation F16D3 and belongs to the E-TEC II family. Structurally, the motor is actually a twin brother Opel engine Z16XE. The same engine can be found on the Opel Astra. Today we will talk in detail about the device and technical specifications of this power unit.

Design of the Lacetti 1.6 liter engine.
Engine Chevrolet Lacetti 1.6 liters, this is an in-line 4-cylinder, 16 valve, naturally aspirated gasoline engine with cast iron block cylinders and a belt in the timing drive. Power system - distributed injection with electronically controlled.
Typical ailments technical problems the motor and its design flaws are well known. Since in our country there are quite a lot of models with this engine. A typical problem is that the EGR valve freezes, requiring immediate flushing. But an even more serious difficulty is associated with hanging valves (usually exhaust valves), due to a miscalculation in the design (the gap between the valve stem and the guide is small). Russian gasoline saturated with resins, which clog the gaps between the valves and their guides. They grab the valves in the guides, sometimes so tightly that the camshaft cams are destroyed! At the same time, the engine control system does not notice the first signs of ignition interruptions and does not notify about this with a signal. Check Engine! But if the engine clearly “troubles” after starting, and after warming up, it barely pulls. This means the problem is in the valves. If the problem is not dealt with, the expensive catalyst gets clogged quite quickly. However, on engines after 2008 this defect was eliminated. The manufacturer's engineers reduced the diameter of the rod and slightly changed the angle of the valve's operating chamfer.
Cylinder head Lacetti 1.6
Chevrolet Lacetti 1.6 cylinder head made of aluminum alloy. There are 4 valves per cylinder, this is a typical DOHC with two camshafts. Special problems the design does not deliver, because the manufacturer provides for the installation of hydraulic compensators, so there is no need to adjust the thermal clearance of the valves. It can be noted quite common problem with perpetually flowing gasket valve cover. Unfortunately, the rather unfortunate design of the valve cover itself leads to this.

Lacetti timing belt drive. The diagram is slightly higher in the picture. The belt is replaced every 60 thousand kilometers. Due to the fact that the pump rotates thanks to the belt, it is changed together with the timing drive, but once every 120 thousand kilometers, that is, every other time. And now main question, what happens if the timing belt on a Chevrolet Lacetti breaks? The answer is clear on the Lacetti 1.6 engine the valves bend! What follows expensive repairs with the replacement of valves, guides, the entire timing drive and other parts.
Engine characteristics of the Chevrolet Lacetti 1.6
- Working volume – 1598 cm3
- Number of cylinders – 4
- Number of valves – 16
- Cylinder diameter – 79 mm
- Piston stroke – 81.5 mm
- Timing drive - belt
- Power hp (kW) – 109 (80) at 5800 rpm. per minute
- Torque – 150 Nm at 4000 rpm. per minute
- Maximum speed – 187 km/h
- Acceleration to the first hundred – 10.7 seconds
- Fuel type – gasoline AI-95
- Fuel consumption in the city – 9.1 liters
- Fuel consumption in mixed cycle– 7.5 liters
- Fuel consumption on the highway - 6 liters
In tandem with the Lacetti 1.6 engine, not only a 5-speed manual transmission was installed, but also a 4-speed automatic transmission. Naturally, with an automatic, the car has higher fuel consumption and accelerates a little worse.
The engine is being modified not for racing but for everyday driving.
Increase in engine capacity to 1900 cm3, modification of the cylinder head, new camshafts, split pulleys, full exhaust on 63 pipes, installed on January 5.1.
And so we have: a Chevrolet L car acetti with an engine capacity of 1600 cm3.
The cylinder block was bored to 81.5 mm. We calculate the engine volume.
81.5 x 81.5 x 3.14: 4 x 88.2 x 4 = 1839557.853 cm3, rounded to 1850 cm3.
Made it a little easier crankshaft. There is a lot of controversy and questions about this, but is it worth it?
From practice I will say that it is worth it. Advantages A little lightweight crankshaft:
Inertial masses are reduced, which negatively affect the fundamental
crankshaft journals, increasing their wear, the engine spins easier and faster.
Cons of relief: Improper or excessive knee relief may impair knee function. idle speed and when high loads the crankshaft may burst.
We install the flywheel from the Daewoo Nexia. It is 5 kilograms lighter than the Lacetti flywheel.
A Sachs clutch will be installed on the engine.
They made lightweight, T-shaped forged pistons. Photos of the weight of the ShPG will be a little later, after some minor adjustments. Let me remind you that the weight of the standard ShPG was 878 grams.
Lightened the piston pins.
Audi piston rings.
The intake channels of the cylinder head were slightly modified and the plane of the head was corrected. Removed
0.05 mm. They did not grind the channels to class 4-5 cleanliness and there is no need to do this.
When moving in the channels, part of the fuel settles on their walls in the form of a thin film and,
if the roughness is very low (polishing), then the fuel continues to move further
into a cylinder. In this case, it will turn out to be redundant, violating the optimal ratio
"gasoline-air" in the mixture charge heading into the combustion chamber.
Accordingly, fuel consumption will increase and exhaust toxicity will worsen.
As a result, it turns out that a lot of effort is wasted, and all the talk about
that “polish the collector - you will get results” lead to results
exactly the opposite.
We adjusted the saddles and increased the internal section by 2mm. The whole thing has been polished.
According to the catalog, we selected larger intake valves by 2 mm.
We installed camshafts, intake 9.8 mm-265 g, exhaust 9.5 mm-262 g.
ECU installation January 5.1. How to install everything correctly is described here
http://rotorman.nm.ru/j5-sport/j5ino.htm We will need to move the reference disk from
cylinder block.
We take the reference disc from the Daewoo Nexia, or Daewoo Lanos, position sensor bracket
crankshaft from Daewoo Lanos.
Module Daewoo ignition Nexia or pelvis.
We installed an intake throttle from a Nexia 1.5, you can also install one from a Nexia 1.6 16V.
We made a transition braid.
Today, January installation is no longer required, which significantly reduces
project cost. The software and hardware complex GMToolsRT is designed to
for diagnostic work on various types ECU and
reprogramming of various control units. If you have an engineering
block, the complex allows you to configure control system calibrations in
real time.
1. Creation of individual, customized firmware for a specific car.
2. Setting up non-standard hardware on engines with
ECU sirius D3-D52, IEFI, MR-140/HV240, Lacetti, Nexia, Lanos, Rezzo, Matiz, Spark, etc. (distribution shafts, receivers with changed diffuser length and volume,
a lot of throttling intake systems, customized exhaust systems on
atmospheric engines. In project turbo settings.
Actually, this is what we have after all the modifications.
Budget of this motor 150,000 rub. The motor was the first, hence the price.
Today it has been reduced by 70,000-100,000 rubles. depending on the configuration.

The Chevrolet 1.4 F14D3 engine is designed for Chevrolet Lacetti cars, Chevrolet Aveo (Chevrolet Aveo). The engine was produced from 2000 to 2008.
Peculiarities. Chevrolet 1.4 F14D3 is modernized version Opel X14XE engine. Many parts of these motors are interchangeable. The engine is equipped with an EGR valve (exhaust gas recirculation system), which allows to reduce the content harmful substances V exhaust gases. The timing drive on the Chevrolet 1.4 is belt driven. When the timing belt breaks, the valve bends. There is no need to adjust the valves; hydraulic compensators are installed here. Malfunctions known from this motors can be the following: hanging valves due to carbon deposits between the valve stem and valve sleeve (the engine troits, stalls, loses power); may clog fuel injectors; the thermostat goes out of order at 50-60 thousand km; A valve cover leak can lead to oil getting into the candle wells, resulting in ignition problems.
In 2008, the engine underwent some changes and was named F14D4. The F14D3 engine has an older brother with a volume of 1.6 liters and a power of 106 hp.
Under normal careful use and timely service using quality oils and fuel, the engine covers 200-250 thousand km without any problems.
