Tonight I raced (on the street) my friend's 84' Camaro with my 87' GN and I totally blew the doors off him. But he told me once I got ahead of him...he saw spurts of white smoke coming out of my exhaust pipes! I was like huh? I was wondering, is that carbon build up from the engine and is this a good thing? Or do I need to take my car into the shop! I heard if you see white smoke...your heads or something have carbon buildup. Please help me with this dillema

Yeah man, that's what I thought it might be! I have new exhaust but haven't put it on yet. I still have my old Hooker system and the ORIGINAL cat and that thing has seem its days. I think it may be clogged and the exhaust may have to go asap. Kinda scared me at first but I keep real good care of my engine and I couldn't figure out why anything would be wrong with it. Thanks again.

Well, technically racing it full out isn't good for the engine with original gaskets and *GASP* 8 head bolts....I've never heard of engine problems from "old lady driving"

You better keep an eye on the condition of your coolant (make sure it stays green and not milky brown) and oil level/colour....You MAY, at worst, have a slightly leaky head gasket or a tiny crack in the head.

A compression/leakdown test will find the culprit if the "white" smoke gradually worsens...if not, count yourself lucky and be careful out there.

When it was said that it was "white" how white was it? Billowy cloud white...thats definate coolant.

Well it wasn't alot of white smoke coming out. It was very little and not very white at all. I haven't changed my coolant in a LONG time but it's still a greenish color. But it really smells nasty=\ You think I should just flush the coolant out and put new coolant in? I know I don't have any cracks on my heads or anything like that. Not to mention no noticeable leaky gaskets and such. The engine runs/looks fine when running. I'm thinkin it's definitely the coolant and my exhaust needs to be changed to my new system soon.
