BobDeSoto Posted June 10 Report Posted June 10 OHV V8 sat all winter inside on a concrete floor, no heat. Started it right up this morning. After ten minutes (maybe less) smoke started rolling out the exhaust. As it continued to run (fast idle) the smoke diminished and finally stopped. Temp was at 180 by then. Gotta be valve stems? Quote
Sam Buchanan Posted June 10 Report Posted June 10 (edited) Probably condensation (water) in the muffler being turned to steam as the muffler got hot. As the engine continued to run all the water evaporated and the "smoke" disappeared. Edited June 10 by Sam Buchanan Quote
kencombs Posted June 10 Report Posted June 10 (edited) 1 hour ago, Sniper said: Color of the smoke? Did it smell of burning oil? Key question. Also air temp when this occurred. Color will tell whether it was oil, condensation or??? Edited June 10 by kencombs Quote
Solution Sniper Posted June 10 Solution Report Posted June 10 Depends on the V8, SBC are notorious for the factory style valve guide seals to be junk and do exactly what you are seeing. Quote
