Engine Hardware for BMW 3 Series E30 (1984-1991)

Clear BMW chassis

Most engine hardware including head studs, VANOS bolts, and exhaust studs can only be used once. While most of the accessory bolts and miscellaneous hardware can be re-used it is often handy to have a spare bolt or bracket just in case one breaks. Any aluminum bolt, such as those found in the N52 engine MUST be replaced no matter the age or visual condition.

the BMW S14 engine factory rod bolts are a notorious weak link when pushing past the original redline. Inertial forces at high RPM place immense tensile stress on the connecting rods, making heavy-duty hardware an absolute necessity.
