Symptoms Of A Bad Valve Cover
![]() |
![]() |
![]() |
![]() |
|---|---|---|---|
Leaking OilIf the oil is located on the valve cover area or coming from that region, you can assume you have a bad valve cover or gasket. Look around the edge where the gasket seals the cover to the engine. |
Burning Oil SmellThe oil leaking out of the valve cover can drip onto the hot engine parts and the exhaust, leaving you with a terrible smell. When you open the hood, the smell should be overpowering, but you might not see where the oil is burning from immediately. This situation can be dangerous. |
Dashboard LightsIf you haven’t been checking the oil regularly, your first sign that something is wrong might be warning lights on the dashboard. You could get the Oil Warning Light telling you that there’s not enough oil pressure in the system, or it could be the Check Engine Light because of defects from the broken valve cover and gasket. |
Misfiring EngineA misfiring engine can be caused by many factors, such as defective spark plugs or trouble with the fuel system. However, a bad valve cover might also be the culprit. The valve cover could be directly over the engine spark plugs. If there is oil leaking onto the spark plugs, the fluid can make its way into the openings. Oil will prevent the spark plugs from working correctly and cause them to foul. |
