Engine BMW M60B40

The M60B40 engine is the first V-8 engine produced by BMW in over 25 years. BMW engineers began the development of the unit back in 1984, but the motor was first introduced only in 1992. To reduce the weight of the unit, the cylinder block and cylinder head are made of aluminum, and the intake manifold is made of plastic.

Frequent problems

The most common problems of the BMW M60B40 engine: increased oil consumption, shaking at idle.

Engine BMW M60B40If you notice an increased oil consumption, you should check the condition of the KVKG and the valve stem seals, which must be replaced if necessary. If cylinder wear is detected, a liner is required, or a complete replacement of the block. Due to the low quality of the fuel, nickel aluminum blocks are subject to rapid wear, as a result of which the compression drops.

If the car shakes at idle, you will need to adjust the phases in the valve timing system. The reason may be in the crankcase gas recirculation valve and the violation of the integrity of the lambda probe.

Timely diagnostics and replacement of worn parts will preserve functionality and extend the service life of the BMW M60B40 engine.
