I had my st205 3sgte swapped out about 8 months now..I never drove it over winter and just started driving it again. I notice anytime i drive anywhere or drive it hard, white smoke(smells like burning) is coming out of the hood vent. It seems to be coming out just left of the intake manifold. I don't know what this means. It barely did it when i was driving it last fall here and there and now it does it everytime i take it out. Just a note, whenever i drove it last year, the intercooler would get really hot to the touch and now its actually cold after i drive it. my sensor for it is broke, does this have anything to do with it? Any ideas would be great!
thanks..

Sounds like it may be leaking coolant onto the exhaust. Check all your fluids. Pop the hood with it running and find the source of the smoke

I'm willing to bet your rear coolant hose near the firewall is leaking. I had the same problem.

I had that problem and fixed it. But now it is leaking oil. Is it possible oil is just dripping onto the manifold?
