The valve cover might not seem like a high-priority part, but it protects your engine’s top-end components and maintains oil control. Over time, even a well-made cover can crack, leak, or warp—especially under high mileage or heavy use.

Best Reasons to Replace Your Valve Cover

1. Oil Leaks Around the Top of the Engine

If you notice oil seeping from the top of your engine, it’s often a sign your Subaru Outback valve cover or gasket is no longer sealing correctly.

2. Burning Oil Smell From Under the Hood

Leaking oil dripping onto hot engine parts creates smoke and smell—both of which usually trace back to a failing Subaru valve cover.

3. Misfires or Oil on Spark Plugs

Oil leaking into the spark plug wells can cause poor combustion or misfiring, which means it may be time to replace the valve cover and install new spark plugs.

4. Visible Cracks or Warping

Physical damage to the valve cover—like warping or hairline cracks—can result in performance loss and should be addressed with an OEM replacement.

Preventive Maintenance During Major Engine Work

If you’re already replacing gaskets, seals, or ignition components, it’s often worth swapping out an old Subaru valve cover to avoid future issues.
