Lately I have been noticing that I have white smoke rollin from my exhaust, when I told my buddy he said when we raced he saw black smoke rollin from my exhaust... I have the Rear manifold leak but im wondering if i have a coolant leak, possible blown head gasket? Any idea's welcome.
Thanks
Zach

 

Black smoke is normal.
White smoke that smells like coolant is usually a blown headgasket, however being as you live in MI and its freezing out I would say the white smoke is prob. normal also.

 

Under WOT, black smoke is normal. Our cars run rich to protect the pistons and valves from overheating. The black smoke is just unburnt gas.
