Reliability, problems and repair of the BMW M5 E39 S62 engine
The new BMW M5 E39, released in 1998 and replacing the M5 E34, has increased in size on all fronts and, to achieve high dynamic performance, the inline six was not enough, especially since the BMW S38 is seriously outdated. It was decided to use an engine with a V8 configuration and the aluminum M62B44 was taken as the basis for the next M-engine, from the existing BMW 540i E39.
The cylinder block was modified: the cylinder diameter was increased from 92 mm to 94 mm, a forged crankshaft was installed with a piston stroke of 89 mm (it was 82.7 mm), the connecting rod length was 141.5 mm, the pistons were modified, for a compression ratio of 11.
Above, on three-layer cylinder head gaskets, are the S62B50 cylinder heads themselves (this is what the M5 E39 engine is called). They are a modified version of the M62B44. Relative to the M62, the S62 has enlarged intake and exhaust ports, uses new valve springs and lightweight valves: inlet 35 mm, exhaust 30.5 mm. The camshafts on the M5 E39 have the following characteristics: phase 252/248, lift 10.3 / 10.2 mm. The variable valve timing system VANOS has been replaced by Double-VANOS (intake and exhaust camshafts). The M5 E39 uses hydraulic lifters and the valves do not require adjustment. Unlike the M62, the S62 uses a double-row timing chain.
The entire intake system has been redesigned: a large intake reservoir has been used, and 8 throttles have been used, one throttle for each cylinder. The diameter of each is 48 mm. Nozzle performance - 257 cc. The exhaust system is modified, with two catalysts. Brains - Siemens MS S52.
All this made it possible to make almost 5 liters from a conventional 4.4 liter engine and increase power from 286 hp. up to 400 hp at 6600 rpm.
The BMW S62 engine was installed on the M5 E39 and on the rare Z8 roadster.
The release of the motor was discontinued in 2003, along with the end of production of the M5 in the back of the E39, but after 2 years the new M5 E60 appeared, with an even more powerful S85B50.
Problems and disadvantages of BMW S62 engines
The main diseases of the BMW M5 E39 engines are the same as those of the M62B44. The differences lie in the smaller resource of the S62B50, due to the maximum cylinder diameter (there is a burnout of the cylinder head gasket) and the active operation of the car. In addition, the M5 E39 consumes oil in decent quantities, do not save on it and change it more often than expected (7000-10000 km is optimal). Also keep an eye on the condition of the cooling system and pour in high-quality 98 gasoline, then your S62 will drive as smoothly as possible for an old car.
BMW M5 E39 engine tuning
S62 Atmo
You can increase the power of the BMW M5 E39 without using supercharging by buying a sports exhaust system without catalysts, with 4-2-1 manifolds, cold intake and making chip tuning. These small conversions will allow you to remove about 430 hp. You can improve the result with more efficient camshafts (272/272, lift 11.3/11.3), cylinder head porting with channel boring and valves increased by 1 mm. With the appropriate tuning of the brain, the power of the S62 will increase to 480+ hp. You can also install a 52 mm throttle, pistons for a compression ratio of 12.5 and the maximum possible camshafts, but you can forget about comfortable operation.
S62 Compressor
As an alternative to a revving aspirator, you can install a compressor and immediately get a lot of power. There are a lot of ready-made compressor kits for the BMW M5 E39, you need to buy one of them and put the motor on stock. The popular ESS VT1 compressor kit blows 0.4 bar and delivers 560 hp. and 625 Nm. There are also more powerful kits (0.7 bar), but their cost is 2 times higher than ESS.
BMW M5 E39 is a car that is a prominent representative of the fifth series of the manufacturer. The very first generation was introduced almost 35 years ago by the model
Story
The manufacturer has made the maximum amount of effort to ensure that his new product becomes successful, bought and can easily compete with other popular models in the automotive market. At that time, the best technologies were embodied in the BMW M5 E39. And they, I must say, are still relevant in the automotive industry. A few years after the premiere, the concern released a four-cylinder engine, which was installed under the hood of an improved car - 520 E39. A little later, the 525 E39 modification was released, which developed excellent power.
Technical equipment
The characteristic of the BMW M5 E39 makes it clear that this car is almost perfect. The volume of its engine is 4941 cubic meters. see, power, measured in horsepower, reaches 400. Torque is also pleasing, its figure is 500/3800 rpm. Thanks to such indicators, up to a hundred, the car accelerates in a little more than five seconds. located longitudinally, in front. Also worth noting is the distributed fuel injection. By the way, the volume of the tank is 70 liters. About 21 liters of gasoline are consumed per 100 kilometers within the city, if we take into account the movement on the highway, this figure decreases by almost 2.5 times - an average of 9.8 liters is consumed. In the combined cycle, a “hundred” takes about 14 liters. This is what distinguishes the first modification of the BMW M5 E39. Technical characteristics as a whole can satisfy even a very demanding driver. The only negative that can confuse is the considerable fuel consumption within the city. However, do not forget that each car has its drawbacks.
Driving comfort
German cars have always been famous for their ease of driving. A person sitting behind the wheel of a BMW M5 E39 feels maximum comfort and the absolute absence of any inconvenience. By the way, this model is the first of a number of cars in which an aluminum suspension was used. It is she who provides excellent handling and high strength. In addition, comfort is greatly affected by how well the seats are made. In this regard, the German manufacturer has also succeeded, since even several hours spent behind the wheel without a break will not affect the condition of the back of the driver or passenger. Behind, it should be noted, it is also very comfortable to be: there is enough space to comfortably accommodate three adults.
Equipment features
BMW M5 E39 is a car with its own characteristics, and they should be discussed. So, for example, a completely unique gas distribution system is installed in the updated engines. The manufacturer also provided for automatic heating of the steering wheel, mirrors and seats, and the possibility of debugging the position of the seats. It is worth noting that you do not need to configure these functions manually. For example, the heated exterior mirrors turn on automatically if the outside temperature is low enough. There are airbags, and the belts (in the event of an accident) adjust themselves according to the tightness of the fit to the body. The suspension is equipped with special springs, which are “compressed” by one and a half centimeters. It also has pretty powerful shock absorbers. And finally, all seats have adjustable lateral support, which allows you to adjust absolutely any position. So in terms of comfort, this car is really good. However, as in many other things.
Perfection
Tuning the BMW M5 E39 is an activity for people who constantly want to improve their “iron horse”. I would like to say that this car has almost everything, so improvements as such are not necessary. But still, if there is a desire to improve something, then several tuning options can be considered. For example, some people want to give their car a more elegant look and change the bumper. For these purposes, the M5 look version would be a good option. Such a bumper costs about 7,000 rubles. Many decide to replace the suspension. Some advise to take a closer look at a company called Weitec. Depending on whether the owner wants to raise or lower his car a little, he will be selected the required size. If you want to make your car more aggressive, you can install an air intake. And finally, a few words about optics. It is also quite often installed, and xenon lamps are the most common option. Looks really solid.
At the end of this story, one cannot but say a few words about the price of the car. Today in Russia it is quite difficult to find this particular car. However, some offer to buy a used car, and I must say, many of them are in excellent condition. The price is not so big for a car with such indicators - about 600 thousand rubles.
When developing the BMW e39, it was immediately supposed to install a V8 engine with 286 hp, given that in those years only hypercars had so many horses, there was simply no need for a more powerful engine, for a car whose mass exceeded 1800 kg, in general sport is contraindicated.
But other manufacturers have noticed that business sedans with huge and powerful engines are in demand. And even marketers realized that by selling sports versions of ordinary sedans, simpler models also start to sell better, and especially all kinds of accessories that distinguish the charged version from the usual one. For example: body kits, nameplates, steering wheels, trim elements, etc.
And then the engineers were still given the green light to develop a sports engine based on the V8, which they so wanted to do for the previous one.
The motor turned out to be noble, 400 hp. And in 1998, the new BMW M5 E39 went into production. Although she was still going by hand. For 5 years of production, almost 20,500 pieces were manufactured.
The BMW M5 E39 was produced only in the sedan body, the station wagon was abandoned, releasing only one prototype.
The heart of the M5 was the S62B50. It was built on the basis but with a very large number of improvements, ranging from the installation of a Vanos valve timing system, individual throttles and ending with a different injection setting. Acceleration to hundreds took 5.3 seconds, and the maximum speed was limited to 250 km / h, but if you remove the limiter, the car will accelerate to 301 km / h. Anyone could remove the limiter, subject to passing BMW driving courses.
There was only one gearbox, 6-speed mechanics, a very clear device, all the shifts were like a rifle bolt.
The suspension is basically the same as the 540i, but the arms are thicker, the springs and dampers are stiffer, and the ride height has been reduced by 23mm.
The brake discs were huge: 13.6 and 12.9 inches. They were quite enough even for the track.
In 2001, the E39 underwent a restyling, during which “angel eyes”, front and rear parking sensors appeared in the optics. The cabin has a large screen on-board media system and an improved audio system.
P.S.
A few years ago I had a chance to ride a BMW E39. Let me tell you something that really surprised me. Let's start with the suspension, the collective farmers say that it is very stiff, but it seemed to me just perfect, we were driving on a not very good road and it was very elastic, moderately hard, while I drove along that section of the road in other cars and they the suspension was already pierced, but on the M5 everything was perfect. At the same time, although the suspension is low, due to the smaller travel, you can drive on rather bad roads without fear of getting caught on the bottom or bumper. With curbs, of course, the problem is, they are all higher than the front spoiler ... and p.e. almost all M5's are cracked.
Motor, at that time I had an E34 525i, and I thought that the M5 would have a very riding motor, which would barely pull on the bottoms and a loud high sound, but it turned out that the M5 had a gurgling, low, American sound and a very large traction on the bottoms, such that in the city you can turn on 5th or 6th gear and drive without problems. Those. you can go anywhere very calmly, but if you stomp the gas pedal, then the acceleration will be just wild, even the rear passengers need to buckle up, because. they are just thrown around the cabin.
Gearbox ... this is a masterpiece, I have not seen more precise switching. But when starting off, you can stall) The clutch is tight and you can accidentally release it strongly.
The BMW M5 E39 was the only car in which I almost got sick, then I also had discomfort in my Adam's apple, as if it had moved)))
And what surprised me in general was the fuel consumption, in the gas to the floor / brake to the floor mode, the M5 consumes no more than 19 liters of 98th gasoline. I expected 30-40 liters).
On many bodies BMW M5 E39 has become a dream come true for me. And I would not want to buy it, I want it to remain an ideal for me, all of a sudden, with a long operation, I will find many shortcomings and be disappointed ...
In the minds of BMW fans, M 5 occupies a very special place. And no matter what generation of this German super sedan we are talking about, M5- it is always something violent, but only when the owner himself wants it. Combine wild temper and comfort, M5 always turned out much better than the "troika" with the prefix M.
M5in the backE39became the third "five" denoted by the letterM.This comfortable car was produced from 1998 to 2004. As you can see simply by the years of production, Emka outlived the usual one by almost two years.E39.The thirty-ninth M5 replaced, according to many, the even more legendary Emka in the backand at the time, the vehicle in question was the fastest production sedan in the world.
Buy BMW M5 E39 possible for 20 000$. Even considering today's dollar exchange rate, this is a very low price for such a powerful, comfortable, stable at high speeds and excellent handling car.
About appearance:
Take a look at the photoM5 E39.It may seem to you that the same car 
you saw it quite recently, but most likely, if you don’t live in Moscow, or some other large metropolis, you didn’t come across an Emka at all, but an ordinary “five” in an M-body kit decorated with a nameplate - M. And in general, if every BMW adorned with the “M” logo is mistaken for an “Emka”, while the EM-Fifth can be perceived almost every second “five”.
Its exhaust will help you recognize the real EM5 - pay attention to the four separate exhaust pipes. 
Also, passing by the "suspect" you can pay attention to its brake discs: the EM-Fifth has them noticeably larger than the regular Five - 354mm in front and 328 in the back - if we are talking about the M5.
Emotional bumpers, door sills, seats and steering wheel - all this is not uncommon on ordinary Thirty-Ninths. Therefore, it is not worth making a conclusion about whether Emka is in front of you or not based on these body elements. In the end, the main advantage of the M5 is hidden 
under her hood, but more on that ina little lower.
If the front width of the 18th tires is 245mm, then the rear is already 275mm. The drag coefficient of the Thirty-Ninth Emka is - 0.31.
A few words about the salon:
With regards to the salon, or rather its equipment. I would like to say that in comparison with the usual Thirty-Ninth, the steering gear ratio has decreased from 17.9:1, before 14.7: 1.
SpecificationsBMW M5 E39
Here it is, the main asset of the BMW M5 E39 - its eight-cylinder engineS62. 
It is worth noting here that it was in the 39th body that the eight-cylinder EM5 first appeared.
Engine S62equipped with eight throttle intakes and with a volume of 4.9 liters, it produces 394 hp of maximum power and 500 N. M of thrust at 3,800 rpm. It is worth adding that the compression ratio in the motorS62 equals - 11: 1.
With a gear ratio of the main pair - 3.15:1,
as well as a six-speed manual gearboxGetrag Type D, 
which was borrowed from the 540th model, Emka takes off from the spot to the first hundred in 5.3s. The maximum speed was limited to 250, but if the limiter is removed, then the EM5 will continue to pick up speed until it reaches 301 km per hour.
Of course, the declared fuel consumption of 14 liters in the combined cycle is simply a smile, as in general, and 21-one liters in urban mode. It is clear that with a recessed gas pedal, the consumption of a beast passing a quarter of a mile in just 14.10 seconds will not be small.
