I know white smoke usually indicates a bad head gasket (coolant burning), and blue usually indicates oil burning, but my situation is a bit weird.

Usually when I first start my car (sometimes on a cold start, sometimes on a warm start), the light grayish/blue smoke will start coming out of the exhaust for a few seconds then stop. It's a good amount and definatly noticable. Valve seals I'm thinking.

But, I've also noticed AFTER driving the car pretty hard and coming to a stop, the same smoke starts coming out the exhaust. I drive normal through 1st, 2nd, and 3rd and I can see the smoke still coming out but then it stops. I bring it up near redline, bostin' and it doesn't seem to smoke....

So I'm not quite sure what the deal is. It seems to randomly smoke a gray/blueish color that sure does smell like fuel (car is running a bit on the rich side)... but I always thought running rich caused dark smoke.

Any ideas?

Thanks!
