i have a built gsr and is blowing white smoke out of the exhaust. when i take the headers off, ports 3 and 4 seems to have coolant in them and is clean with no black carbon residue. where as for ports 1 and 2 seems to be dry w/ minimal amounts of carbon. i recently changed my head gasket and is still smoking. i also notice that my idle is bounicing anywhere from 1000-1500. car doesn't overheat or anything. what could be the problem?


The head gasket is letting coolant get into the cylinders, or the intake manifold gasket is letting coolant through. My guess is the head gasket. You might need to get the head milled.
