I tried searching for this but I really couldn't find a good way to describe it. The problem his my car smokes a light blue ONLY after I turn the car off and then turn right back on around ten minutes later. Kinda of a steady flow, engine is idleing fine, no sputtering, just a light stream of smoke out the tail pipe. What do you guys think this could be? Car has 91,000 miles and the comp. test showed 200, 180, 205, 190. Please help, kinda annoying. TIA

crap in the catalytic convertor, if you havent changed it yet it might be a good idea

valve guides could be leaking but it also could be the cat...

sounds like either a bad ring or a bad valve guide on the piston with 180 compression, i think all cyliders should be within 5-10% of each other when doing compression, if not i believe you might have problems, just my 2 cents, but it could be your cat too

Thanks guys, I believe I will try to look at the cat tomorrow. Other then that I guess it is back into the engine. . .
