Using an old camshaft can pose serious risks to overall engine performance. As camshafts wear out, the valve timing may become inconsistent, causing a noticeable drop in power output and fuel efficiency. Damaged lobes on the camshaft can prevent valves from closing completely, which may lead to compression loss or even engine backfire in severe cases.Furthermore, increased friction between components can accelerate wear on critical parts like lifters and camshaft bearings, potentially resulting in expensive engine repairs. To avoid these problems, regular camshaft inspections and timely maintenance are essential. They help maintain optimal performance and extend the life of your engine.
BMW vehicles that experience exhaust camshaft related faults while driving are usually accompanied by specific warning lights coming on, such as the ABS light and engine malfunction light. In addition, the vehicle performance may be reduced, acceleration may be weak, and in some cases, the engine may even experience unusual noise or vibration. This is usually associated with the camshaft position sensor. The cause of the malfunction may be wear and tear, poor lubrication or timing chain failure. Ignoring these problems can lead to serious engine damage. Timely detection and regular inspection and replacement of BMW camshafts can avoid costly repairs.
