Weight-saving measures include aluminium chain cases, oil sump, motor mount arms, accessory mounts and a cartridge-style oil filter housing. Other features included a forged steel crankshaft and tubular stainless steel exhaust manifold instead of the more typical cast-iron items.

BMW also fitted hydraulic motor mounts to decrease the inline four's inherent noise, vibration, and harshness compared to the smoother straight-six engines in production at that time.

When installed in the BMW E30, a two-piece oil pan with a removable front sump was fitted to the M In this two-piece arrangement, the upper oil pan casting incorporates the oil pump's supply passage, and is sealed to the crankcase oil filter housing with a paper gasket.

This can cause problems, because thermal cycles and engine vibration tend to loosen the upper pan mounting bolts inside the motor. All versions featured a low-maintenance timing chain with a self-adjusting hydraulic chain tensioner and hydraulic valve tappets. The M42 uses the Bosch Motronic M1. In markets that required emissions controls, the DME also incorporates an oxygen sensor and three-way catalytic converter.

Boring and honing with the cylinder head off will produce a block with round bores when un-assembled, but slightly out of round when assembled. In serious race engine preparation solid torque plates are bolted onto the block at factory torque specs to simulate the cylinder head bolt loads.

Engine Chips

Boring and honing is performed with the torque plate installed to produce a bore that will be more perfectly round when the cylinder head is installed. This produces better ring sealing and longer ring life. All Korman engines, from stock to full race, are machined using a torque plate. Valves and valve seats. Valve seat grinders in common use are not appropriate for BMW cylinder heads.

BMW valve seats are so hard that they spoil the surface of the grinding stones causing rough and imprecise seat surfaces.Recover Lost Password. Password must be at least 8 characters.
