When i rev my car up blue smoke blows out the exhaust what is casing this i just changed my thermostat from a 195 to a 180 can this be causeing this.

 

if its blue, its oil
if its white, its coolant
if its black, it's unburned gasoline

 

it look like white when im driving down the road and have the car in gear and goose it it dont blow anything but if i let off the gas and come to a sudeen stop i see smoke blow by me

 

Get out and try to smell it and tell us if it smells like oil. If it is blue than it is oil. It has nothing to do with your thermostat. Does the smoke go away after you have been driving for awhile? My valve seals or so bad that when I drive it takes about 15 minutes for it to stop smoking.

 

I'd also guess it is your valve seals. I just rebuilt my engine which smoked the same way yours did. When I took the valve springs off the seals (both intake and exhaust) just crumbled in my hand (if there was anything at all left). But, still smell the smoke and tell us what it smells like.

 

my motor has just been was rebulit about two years ago and ive only put about 4000 miles on the motor it just started doing this today

 

is it coming from the tips?

 

yes it's coming out the exhaust tips

 

i asked b/c about two weeks ago i was driving and i noticed alot of somke coming from the back of my car when i was driving but it wasnt coming from the tips. mine was coming from my tranny and it was hitting the exhaust and smoked. mine smokes for a sec when i start it up and i have been told its the valve seals but maybe one of these guys wil know

 

hey guys it me again with the infamous red thing.... anyway im having a similar issue where mine seems to blow some smoke out the exhaust tips. i cant really tell but it seems like either a very dk blue or black tint (most probly a rich condition cuz i dont smell any oil and level isn't dropping) it seems really bad after revving or idling or other random times... it kinda smells rich, and im gonna check it out with the winaldl....

the q is, if thats the problem, how would i lean it up? i tried the iac adjustment in the tech section of the main site but it would barely run w/o stuff plugged in (unless the instructions mean somethin else from what im doin) and rite now i cant do open air cuz after insurance im broke, so whatever you can give me will be appreciated, and i hope this helps you out too, camaro89rs355.

thanx, :hail:
