Camshafts and lifters play a key role in your engine’s performance by controlling the timing of the intake and exhaust valves. Together, they help regulate the airflow into and out of the engine, ensuring smooth combustion. Over time, these parts can wear down, causing engine misfires, poor performance, or strange noises. Replacing them with genuine BMW parts can restore engine efficiency and prevent further issues. All non-electric BMW vehicles, such as the BMW 3 Series and BMW 7 Series rely on these parts for reliable engine function.

What Do Camshafts and Lifters Do?

Camshafts control the opening and closing of the engine’s valves by rotating in sync with the crankshaft. Lifters, or tappets, push on the camshaft lobes to operate the valves. This coordination allows the engine to intake air and exhaust gases at the right times, keeping the engine running smoothly and efficiently.

Why Do Camshafts and Lifters Fail?

Camshafts and lifters can fail due to improper oil maintenance, excessive heat, or high engine mileage. If the engine oil isn’t changed regularly or becomes contaminated, it can cause the lifters to wear out and the camshaft lobes to deteriorate. When this happens, engine performance drops, and it may become harder to start or run smoothly.

How to Replace Camshafts, Lifters, & Parts

Replacing camshafts and lifters requires removing the timing components and disassembling parts of the engine. It’s a labor-intensive job best left to professionals.
