Hey everyone I have a 1990 GMC Sierra 4x4 5.7 350 V8 I just finished putting new head gaskets and intake manifold gaskets on it. The truck is smoking but only when gas is pressed. It’s a white smoke I don’t think it’s blue. It’s not a head gasket issue due to not loosing coolant plus it has brand new ones. Not loosing any oil either that I can tell by looking at the dip stick. Please if you have any advice or know of what could cause this please help. Thanks!!
