Oil on Y Pipe???

[L36Camaro]

I did an oil change a couple weeks ago, and now whenever I drive there is a stain of oil on the Y pipe right in front of the drain plug. Today I drove it hard, and smelled burning oil so I looked under the car and on the Y pipe it was smoking and there was a stain of oil. Is that oil there from when I changed the oil and it’s still burning off, or is it leaking? I’m starting to think it’s leaking. Did I over tighten the drain plug, or is the drain plug too loose? Or am I just worrying about nothing, and it’s just oil that spilled when I did the oil change and it’s burning off? Thanks! [img]smile.gif[/img]

I generally like to wipe around the drian plug and get all the dirt and grime off so if I ever suspect a leak, I can simply look and see.

I had a similar problem......mine is a small leak on the rear main seal....pain in the arss...yours could be different, may be the pan gasket is losing its seal, or your drain plug isnt tight enough or is faulty in which case try a new plug. Happy Hunting. [img]graemlins/barf.gif[/img]

Should I get a new Drain Plug and a little drain plug gasket? I was also thinking of getting some kind of de-greaser and wiping it on the oil pan and y pipe until they’re perfectly clean, then checking them again in a few days to see if there really is a leak. Does that sound like a good idea? Thanks!

yeah, that would be the best thing to do in my opinion. that will only cost a little bit of time and money. take it to a self service car wash and power wash the underside really well after you degrease everything. degreaser works alot easier if the engine and components are warm/hot.

The GM part number for the oil drain plug *gasket* is #14090908. Comes in a package of 5.

It is a steel washer with a neoprene rubber seal molded in.
I highly recommend it, no more leaks.

I would do that before I bought anything.
