a little bit confius..a lot of steam flow out from the exhaust,when i start my engine in the morning..my engine just top overhoul and port n polish about last week..the steam only happen in the morning..is it bad or good habbit for my engine??
Perhaps it's just a water vapor caused by a cold temp from the midnight until the morning. Does it still happen after the long run or during a sunny day?
its normal,when u start your car, place your hand at the exhaust outlet, if u feel damp means its vapour...nothing wrong with it. same thing happened to me after major rebuild of engine.
