Re: 3.0L rebuild or no
I would'nt just rebuild the engine without first knowing what is actually wrong with it, firstly white smoke is usually caused by water getting into the combustion chambers and burning off, you say that this only happens at start up?? if so then you may have a cracked head if it had over heated enough, and once the engine gets warm the thermal expansion in the head structure seals up the crack. Did you get the manifold checked for leakage?? Who replaced the head gasket?? did they check for straightness or cracks?? What was the initial reason for the overheating issue?? Outdrive pump?? circulating pump?? thermostat?? Lots of questions to answer then maybe we can help you a little more. Good luck.
