Common Engine Valve Cover Failure Symptoms
- · Aging and Wear: Over time, valve cover gaskets can harden, shrink, or crack, leading to oil leaks and burning oil smells coming from the engine.
- · Improper Installation: Uneven torque or incorrect gasket placement during installation can cause leaks and sealing issues.
- · Material Fatigue: Constant exposure to high engine temperatures can cause plastic or metal covers to warp or crack.
- · Blocked PCV Valve: A clogged PCV system can cause excess crankcase pressure, potentially damaging the valve cover or gasket.
