Hey everyone.Just a question on my 98 s320.I just did the head gasket because it was leaking oil.Now its about a month later & notice another leak.It seems to come & go & is located behind the air pump, pass side.Isnt the oil level sensor located in that area?My pan is a one piece design.how do I get it out of there?Can I jack the engine or does it need to come out?Thanks a bunch.
