Blowing Smoke After Idling - Otherwise Known as ?What Do I Order From Jerry??

[Erik]

Again, looking for some help.

Of late, I?ve noticed a couple of times when the car is warm, and sits running for a while, it blows a puff of smoke out of the back. Looks like it?s gotten a bit worse of late, so I did a little investigated today. She did get a good Eye-talian tuneup today, with some ZR-1 appropriate highway speeds. Through all of it, no signs of any smoke. Actually, I?ve been impressed with how little oil it burns overall. So I don?t think there are any major issues inside the engine.

Poked around here a bit, and came up with some references to the fuel somethung gaskets going bad, and letting oil up into the plenum, which then burns off in the first acceleration. Sounds like what I am experiencing. Oh, and mine only does it out of the right exhaust pipe.

Anyone have any thoughts on this? What parts do I need to address it? What else is worth doing while it?s this far apart?

Thanks again, everyone.
