VMF Posted February 12, 2004 Posted February 12, 2004 i noticed recently if i floor the pedal while driving i have grey smoke coming out. whn i floored the pedal while car was parked there was no smoke at all. is this my crankshaft and camshaft seals?
UCF3 Posted February 12, 2004 Posted February 12, 2004 Can't tell you. Need to rip apart your block, and check all the seals.
jschunke Posted February 12, 2004 Posted February 12, 2004 Blue smoke indicates burning oil. White (grey?) smoke indicates excessive fuel not being combusted. So the problem does not appear to be terminal. Either the injectors are dumping too much fuel or there isn't suffiecient spark in one or more cylinders.
VMF Posted February 12, 2004 Author Posted February 12, 2004 hmm insufficient spark.... and how do you test for this? i recently changed all the cables and spark plugs. i used denso cables and denso iridium spark plugs., i changed rotors and caps as well. aslo why dont i get this smoke when i rev engine when the car is not moving?
UCF3 Posted February 12, 2004 Posted February 12, 2004 i was hoping to avoid it:( Hey, it's still cold up there, isn't it? It could be header leak. I've seen cases where that has happened and slightly dark grey smoke has come out during acceleration. This might be something you might want to tackle during Spring. In the meanwhile, you could use some of the additives to seal up some leaks. Time to visit Autozone. :whistles:
VMF Posted February 12, 2004 Author Posted February 12, 2004 You mean heater? heater core? ouch! but i dont get any funny smells in the cabin
SRK Posted February 12, 2004 Posted February 12, 2004 VMF it is completely normal for the exhaust gas at the tailpipe to go slightly grey under full throttle. The WOT switch tells the computer to go slightly rich to improve power, and also to heat the cats to clean them. The result is a grey smoke under full load. From idle just reving the engine won't do this. It also sounds like the car is running properly and that there are no other symptoms. Don't worry about it at all.
VMF Posted February 12, 2004 Author Posted February 12, 2004 ok i'm releived now:) i also didnt notice any oil or coolant consumption whatsoever. so i guess i'm all good:) thank you guys:)
BlackSC4 Posted February 13, 2004 Posted February 13, 2004 yeah that happened to my sc. my friends was all shocked as you were vmf, they suggested it's an exhaust problem. who knows, but its been running like that for a whiel now and theres no problem, so i ruled it out as being normal.
jzz30 Posted February 13, 2004 Posted February 13, 2004 when there is load applied to a motor carbon seems to puff out the exhaust, like when doing a burnout you frequently see it
