When I start up my 85 Iroc smoke pours out the exhaust but then clears. It happens the most when its cold, but alittle on every start. The smoke looks blueish. I was thinking a fuel injector cleaner or an engine flush may get rid of it but, I don't know what is wrong with it.

 

VALVE STEM SEALS.

 

Yep, try some valvoline max life. It's supposed to soften up the seals.

Maxlife aye? I'll try it! Some bonehead stored my IROC for 5 years before I bought it...The low mileage rocks but it sucks when it smokes every damn time I start it!!

And i'm definately not in the mood to change valveseals. haha

Hey thanks, I'll try it out.

 

It wont help. Thats the oil Ive been using for awhile and mine still smokes pretty bad at startup. I swear I think the valve seals fell off lol. I have the seals, valve springs, new plugs, and all the tools to do it except the air compressor but im to lazy..
