Let’s take a closer look at the technical characteristics of the M62B35 engine. It began to be produced in 1996 and up to 2003 pleased customers in the general market. The cylinder block consisted entirely of aluminum, and as a power system was again driven by an injector. The engine has a V shape and the necessary 8 cylinders for full performance. Each of these cylinders has 4 valves. The stroke of the piston here is usually 78.9 millimeters, while the diameter of the cylinder itself is at 84 millimeters. And all this data is realistic with a compression ratio of 10. The volume of this power unit is 3.5 liters. Its power at 5800 rpm equals 235 horsepower. Torque in the maximum variant shows 320 N*m at 3300 rpm.
The developers recommend to use gasoline not lower than 95 grade. The motor has Euro 2-3 environmental standards. On the highway, the consumption of the device is approximately 9.1 liters per 100 kilometers, on a mixed road it will already increase to 12 liters. And in urban conditions, its value will be 17 liters per 100 kilometers, which can not please the owner of the car. Oil for 1000 kilometers of distance traveled goes about 1000 grams. In the engine it is recommended to use oil 5W-40, 0W-30, 5W-30, 0W-40. At the same time in the unit the volume of oil is equal to about seven and a half liters of oil. It should be changed once every 7-10 thousand kilometers. The operating temperature here reaches approximately 105 degrees Celsius.
In practical conditions, the engine life can exceed even more than 400. And tuning will help to achieve in potential even more than 400 horsepower. This engine can be installed on BMW cars with the index 535i or 735i. These are the characteristics of the M62B35.

Disadvantages
People often notice leaks on these units. Most likely the valve cover gasket needs to be changed. If the coolant bath is leaking, the coolant bath itself should be changed, in extreme case replacing the intake manifold gasket and the pump gasket will help.
Engine knocking. These sounds are constantly encountered when the timing chain is stretched, its useful life is already more than 150 thousand kilometers. The bypass and tensioner strips and the Vanos system have a similar service life.
The car floats at revs. Air is sucked in the intake manifold, which can cause erratic operation. KVKG, air flow meters, throttle valve position sensors may be broken. At the time of tightening the connecting rods and the internal combustion engine has problems.
Even at a sufficient stage of driving the oil consumption will increase significantly. The caps are bad to remove, but they break quite rarely too. And the generator in this case, too, will not be able to work for a long time. Therefore, you need to treat the engine well, pour the right fluids in time and perform technical inspection.

Technologies
After this engine M62B35 forced its predecessors out of the market and into the assembly line, the short stroke crankshaft was in the previous block and remained in the one described above. The cylinders, on the other hand, were reduced in diameter. Nicasil casings were used for a short time, and after a while the main material for this part became alusil. In this model, modern pistons were introduced, while metal ceramic connecting rods remained the same.
The heads on the cylinder block have been improved, the camshafts have been refined. Phase and lift have been given completely new values. Springs, plates and valves remained the same, but the exhaust and intake diameters changed slightly in the right direction.
The cylinder-head cover is now fully magnesium, and the timing chain had only one row. The life of such a part would be between 150 and 200 thousand kilometers. The intake manifold has been improved, and the modern throttle plates and ignition coils are almost the same as before. Only one thing has changed, there is now a thermostat that could be programmed. The latest system from a well known developer helps with all the tasks at hand. Reviews show that the improvement and liner on the M62B35 engine helps to solve a lot of problems and prevent them.
This unit is used on BMW cars, which have the 35i index. In 2001, the smooth replacement of these motors with modern and improved ones began. Further, they completely ousted such engines from the market. Drivers rate this unit as very good.
Modifications
There are virtually no major modifications in this species. The only major change is the TU. Its power at 5400 rpm is 286 horsepower. And here the maximum torque in this case will be equal to 440 N*m at 3600 rpm.
Chip – Tuning
It is possible to increase the power of the BMW M62B35 by using a Vanos. You will need an intake manifold and wide new channels. Distributive shafts will help in sporty exhaust and full tuning of the car. As a result, it turns out about 330-340 horsepower. In urban conditions, the car will feel comfortable.
If you need more than 400 horsepower, you need to use a compressor. There are a huge number of these parts in the general market, which helps to choose the most needed one. The cost of such a service will not be cheap. It is necessary to buy a new kit, a pump from a well-known manufacturer and at a pressure of half a bar you can get more than 400 horsepower. For a turbo it will be unprofitable to redesign the above motor.
