Help, White Smoke!
 

Okay so I searched and didn't come up with anything too helpful. I have white smoke coming from up under the car after I drive it hard. It doesn't leak a drop of anything and it runs and starts great. It looks like it is coming from the middle of the exhaust by the cat. It never comes out of the tail pipes. The smoke will come out from under the door and up by the firewall. I can't really describe the smell but it's not fuel or coolent. I don't think it can be coolent because it's always at the same level. My guess would be something in the exhaust. Maybe a clogged cat? Anyone got any any ides?

Oh yeah it's an 88 vert.

Exhaust leak.

you sound pretty sure about it........I thought it would be something in that area.
