Symptoms & Diagnosis

Warning Signs Your Valve Cover is Failing

  • Oil leaks around the valve cover gasket area. You might see oil pooling on the engine or smell burning oil.
  • Engine misfires. A faulty valve cover can cause oil to leak into the spark plug wells, leading to misfires.
  • Rough idling. Oil leaks can affect engine performance and cause rough idling.
  • Whistling or hissing noises. Cracks in the valve cover can create vacuum leaks, resulting in unusual noises.
  • Check engine light. Various issues related to a failing valve cover can trigger the check engine light.

How to Test if This Part is the Problem

  1. Visual Inspection: Carefully inspect the valve cover for cracks, leaks, or damage. Pay close attention to the gasket area.
  2. Oil Leak Check: Look for oil pooling around the valve cover and spark plug wells.
  3. Pressure Test: A mechanic can perform a pressure test to check for leaks in the valve cover.
  4. Smoke Test: A smoke test can help identify vacuum leaks caused by a cracked valve cover.
  5. Spark Plug Inspection: Remove the spark plugs and check for oil contamination.

Common Failure Causes for This Part

  • Age and wear. Over time, the valve cover can become brittle and crack due to heat and pressure.
