An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.

    Had a leak for a month before I got it fixed. It was leaking from the rear of the engine. My mechanic said that it was a 22 cent o ring that goes on these vehicles a lot.
