On my 89 Pirata I replaced both exhaust manifolds and risers a week ago. I had it out for the first time this past weekend and on startup the manifolds were smoking at the engine ports. I expected some from the paint and what not but it continued to smoke a fair amount anytime I got on it. I obviously used all new gaskets and I'm not sure what exactly is going on. The smoke smells awful and I suppose like burnt paint? Definitely not oil or gas. Just wondering if anyone has ran into this or not? I did read that i should have put a different gasket that blocks the front port on the risers to force water over the riser and I ordered new ones but I still dont see that making smoke at the engine? Any help or suggestions is appreciated.
