Engine M60B30 – V-shaped 8-cylinder gasoline engine, the first V8 engine manufactured by BMW in 25 years. To reduce engine weight, an aluminum cylinder block and cylinder head were used, as well as a plastic intake manifold. The cylinder liners are Nikasil metallized. The connecting rods and pistons have also changed with the V8 design. The dry weight of the engine is 203 kg. The M60 engine has 4 valves per cylinder, 2 overhead camshafts, driven by timing chains. Each cylinder has its own ignition coil, fuel delivery and ignition angle are controlled by the Bosch Motronic 3.3 system.

— official information
- Shaking the engine at idle speed. You can fix the problem by adjusting the valve timing. It is also necessary to diagnose compression, lambda probes and check the crankcase gas recirculation valve.
- Increased oil consumption. You can eliminate the malfunction by changing the KVKG, as well as the valve stem seals complete with rings. If the cylinders themselves wear out, either the block or its liner will need to be replaced.
To this we can add that with poor quality gasoline, Nikasil blocks become unreliable. They age quickly, lose compression and undergo accelerated wear. For this reason, it is better to take units manufactured after 1994, equipped with alusil sleeves. Maintenance of the M60B30 motor is slightly more expensive than the M50 version. In addition, the V8 offers improved fuel consumption. For the sake of completeness, it should be added that the engine has a large age and mileage, as well as intensive use in the past. Therefore, age-related problems are added to all the shortcomings.
