2004 Cadillac CTSI have oil where the spark plugs go what should I do?


I am going to assume you have the 3.2L or 3.6L engine. Have the valve cover gaskets and o-rings replaced. Not a huge deal if you want to wait awhile before repairing it. Just make sure to keep the engine oil level topped off.

Valve CoverIf this is the 5.7L engine there are no o-rings to replace, just the valve cover gaskets.

 • Do not remove the oil fill tube from the cover unless service is required.
   • If the oil fill tube has been removed from the cover, install a NEW tube during assembly.
