White is normally water being burned, usually from a bad head gasket. Bob

+1 on a possible headgasket issue. only way to fix it is to pull the head(s).

As Bob and others have said, it is 99.99994% likely you have a blown head gaskets. I would avoid driving it until the problem can be diagnosed and fixed.

Lightbulb maybe..

do a bit of investigating??
Compression test?
Plug read?
Cooling system pressure test?
Coolant loss?
As others have mentioned, keep driving it, if it is a gasket, and you can count on a rebuild, when the antifreeze ****** up your brgs, etc...

working on pulling the heads, noticed some oil in the valve covers, everything looks normal so far, should there be any oil in the valves and valve cover. Should I do a valve job while I got the heads off and a pvc conversion to the ls6 valley cover. Just looking for some insight to fixing this problem. What do you guys think of the patriot stage II heads?

I thought when you blow a headgasket the smoke actually looks like steam and you have a coolant smell. Also, I have always thought you would have coolant in your oil.

I remember having white smoke coming from my exhaust from my supra. Replaced the valve seats and the problem went away. I see people pre oil restrictors blowing white smoke out of the exhaust at idle.

White is normally steam, and you don't always see coolant in the oil. There is a different in color between steam and oil, the oil will be a bluish color. Bob
