smoke

WVSNS& · December 21st, 2005, 02:07 PM

Has any w/a 4.6 dohc experienced smoke at startup as a regular thing?

AtlanticBlue99 · December 21st, 2005, 04:15 PM

blue smoke- ike burning oil or what color smoke coming from where?

99mustang232 · December 21st, 2005, 04:32 PM

probably a sign of warn valve seals, does it smoke on startup then go away... and smoke more the longer it has sat?

99mustang232 · December 21st, 2005, 04:45 PM

Oil smoke after startup from an engine that has been shut off for a while is usually the result of worn valve guides or valve stem seals. When the engine is shut off, the hot oil leaks past the seal or guide and drips down on the piston top. When the engine is started, the oil burns off and creates the smoke for the few seconds of operation

Smokes at start up and quits after about ten seconds from the tailpipes. Smoke is mostly a grey w/a hint of blue but real suttle.

could be just a little bit of minor oil burn off like posted up there^^

Bill · December 21st, 2005, 06:05 PM

maybe its just steam from the condensation in the exhaust system

99mustang232 · December 21st, 2005, 06:25 PM

blue smoke = burning oil

AtlanticBlue99 · December 21st, 2005, 06:30 PM

yea blue smoke= burning oil, a clear haze is just normal for winter time lol. hopefully it isnt anything too serious, your CEL isnt on is it?

WVSNS& · December 21st, 2005, 07:25 PM

No codes yet.Got a steeda oil seperator too.

99mustang232 · December 21st, 2005, 07:32 PM

mine does this too w/80k on the ticker... not much you can do unless you wanna pay for a valve job? im sure you could also do a leakdown test... but this is a common problem not just for mustangs.

Is your Cobra supercharged?

WVSNS& · December 30th, 2005, 07:14 PM

No supercharger. Last year of the na. The valves and heads were done 10k ago and the steeda seperator seems to work well. Still get a bit at start up but not anywhere close to what it was.

it's leaking past the valve guides and seals.

99mustang232 · December 31st, 2005, 04:57 AM

john sounds to me like you need a sweet cam and some reworked heads

Casper98GT · January 2nd, 2006, 04:13 PM

Have a 97 Cobra that did the same thing. Shut it off, and some white smoke would breeze out of the tailpipes. I had a problem with the IMRC's the controler decided it didnt want to work anymore. So i also removed IMRC runners and cleaned them up and worked them back and fourth. Havent seen much smoke anymore. My 98 Gt lets out a small amount nothign like the cobra did though. Also have seen Worn valve guides like others have suggested. And the 32v's do have problems with valve's leaking by. had a 91 Gt that did it for a good minute or so, valve seals were pretty bad in it. lol.
