The camshaft has a critical job that impacts engine performance and efficiency. As the camshaft spins, the cam lobes open and close intake and exhaust valves, which is vital to the engine's operation. If the lobes become worn or damaged, the engine will suffer drastically. It is imperative to replace the camshaft when damaged or when wear occurs to prevent costly repair bills and to ensure the engine is operating smoothly and efficiently.

Stock replacement hydraulic valve lifter for the M52, M54 and S50 S52 engines. These lifter buckets can last 150,000+ miles but then they no longer fit on the valve stem correctly and a ticking or knocking noise can result. If the lifter is no longer seated correctly, it can lead to the valve not opening correctly. Replacement is straight-forward but requires special tools for working with the camshafts.

1995-1998 E36 BMW 323is 323ic 328i 328is 328ic M3
