my exhaust puts out gray smoke when i rev it, like going in first if i bump the rpms up to 2k to go it see a puff of gray smoke leaking oil?

 

pretty sure gray smoke means your burning oil. gray smoke=ok...black smoke=not ok! so just check your oil but you should be alright!

 

just changed it, doesnt seem ok why would i be burning any

 

might be your rings

 

running rich... stand behind it and get someone to rev it slightly, if it feels as though its burning your eyes, its running rich Believe me, you can smell it!

 

I think you have it backwards . Black smoke is from running rich /carbon . If you look at the tail pipes on almost any SS/SC they will be black . My car will smoke black when i get on it from time to time , it's normal.

 

I think Id rather burn Gas then Oil anyday..
Gas you can fix easily with a tune.
Oil you got Physical Motor issues

 

absolutely , the gray color is something to worry about . Black is normal thou.

 

blown head gasket maybe? are you sure its gray and not white? could be you're getting coolant in the combustion chamber somehow..

 

its not ganna be coal black its not like hes in a desiel truck. im smoke when i get on it at first. nothing wrong with it. it did it stock and after the tune.

 

totally smells like it is running rich, i dont even have to be behind it, a good wind and i can smell it in the drivers seat, would that explain the gray smoke? it doesnt smoke often that i can see just when i quickly bump the rpms so i dunno.

 

sounds like mine

 

so its all good then? i hopee
