The M60B40 served as the model for the small V8 M60B30, which had a cylinder block with a short-stroke cast crankshaft (stroke 67.6 mm as opposed to 80 mm for the M60B40) and a cylinder diameter of 84 mm instead of 89 mm. Pistons and connecting rods were replaced, respectively.
Cylinder heads from a 4-liter engine, with exhaust valves reduced to 28.5 mm (previously 30.5 mm) and intake valves reduced to 32 mm (previously 35 mm). Standard BMW M60B30 camshafts have phase 246/242 and rise 9.7/9.4 mm.
The M60B30 still has a plastic intake manifold, a double-row timing chain, and individual ignition coils, but it has a smaller throttle diameter of 70 mm than the M60B40. Engine management system Bosch Motronic 3.3.
Other modifications of M60: M60B40.

Disadvantages of the M60B30 engine
A nikasil coating, which is terrified of sulfur in fuel, was in use until 1994;
Changing the valve timing frequently reduces engine vibrations at idle;
The crankcase ventilation system or the valve stem seals are the cause of the oil burner;
Checking the oil pump screws is advised because they could come loose and fall into the sump.
The owners discarded factory catalysts because they were a limited resource.
