Thread: Small oil leak, need help

He guys.

I am relatively clueless, so go easy on me.

I have a 2001 Grand Prix GT 3.8. I have a small oil leak, that seems to be originated somewhere just slightly behind the oil filter (towards the middle of the engine)...no more than 4 inches beyond. I'm seeing a few tubes, maybe some wiring just behind there, I think it's coming from a tube. Could anybody tell me what I am looking at!?!


thanks in advance.

Judging by that answer, doesn't sound like a very common place for a leak. The cars currently on blocks in my driveway right now. :P I have already removed the passenger side tire, cleaned the area in and around the oil filter, its not coming from the filter, as I originally thought, as I've had some shotty mechanics not tighten filters properly, but this one is fine. I don't see any drops coming from any higher into the engine then what I previously described. It seems to be coming from a hose (??) just to the inside of the filter, and its dripping down onto the axle shaft, then to the ground. It's small, I lose about a quart of oil, every 3 months or so.

Okay, after further inspection, this is the best I can describe it. Definitely not coming from higher up in the engine, or the filter itself. The part of the engine that the oil filter is mounted on. There's also a wire that plugs into it right behind the filter. Oil is leaking from that "housing" I guess you would call it, and coming out right where that wire connection is.
