white smoke
is coolant the only thing that could cause this?
i torque the manifold down in sequence at the proper torque spec.
i dont believe its the intake leaking, i ve done so many of these.
but what else could it be.
its a full size chevy with 168k miles on it. stock
I would suggest checking the oil and making sure you havent made a milkshake. Really there are only a few things that could have happened,
1. head gasket blown
2. intake gasket bad (either not seated properly or torn)
3. crack in a coolant passage.
Is it better/worse when warm?
Give us more info
