The BMW M62 engine was released to replace the M60 and was produced from 2001 to 2003. The design is an 8-cylinder piston engine. The gas distribution mechanism in the M62B46 versions is equipped with the VANOS variable valve timing system. The pistons are cut out to the ring area. Sintered rods are highly durable and lightweight. The peculiarity of manufacturing allows you to accurately center the connecting rod body with the bottom cover.

Frequent problems
The main malfunctions of the M62B46 motor are: knocking, rough idling, leaks. The reason for the knock that appears may be an extended timing chain, which has a service life of up to 200 thousand km, as well as a tensioner bar, a chain bar, a tensioner. The resource of the Vanos system is similar to the resource of the chain, and it can fail. It is better not to delay checking and replacing.
When the engine runs unevenly, the cause is air leakage in the manifold, problems with the flow meter and KVKG. The malfunction is caused by dirty throttle valves, faulty throttle position sensors.
If you notice a leak, you need to check the valve cover gasket, coolant bath, pump, outlet manifold gasket.
With increased oil consumption, the valve stem seals must be replaced. It is better to use the oil recommended by the manufacturer. After 200 thousand kilometers, the resource of the engine cushions is outleted. With timely care and replacement of worn out elements, the motor will last a long time.
