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.

    O ring leaked oil. I don't know as I don't understand car mechanics but it did leak. It was repaired and everything is fine now.
