Ok...all of a sudden my car is blowing out some nasty smelling white smoke out of the exhaust everytime i get out of the throttle...doesnt do it at idle and doesnt smoke while my foot is on it...i did the obvious checks.....no coolant leaks or contamination...oil level is still full...i'm trying to find someone right now with a compression tester so i can test it for ****s and giggles but as of now i do not know why it is doing that....any ideas or suggestions....and please dont say search....because I did and didnt find anything with good information.

dont be shy people i'm sure someone has a great idea because i am out of them

 

what is your afr when doing these wot pulls? also what fuel do u use?

 

i do not have a wide band to tell you the afr's but its not only under wot...anything about 5lbs i would say and my girl is smoking...def doesnt smell like she is running rich it just smells like ****

 

any other takers?

 

Your going to need to do that compression test to know for sure....Sounds like it might be a headgasket though.

 

yea the compression test will be done tomorrow afternoon that is the earliest i can get my hands on a compression tester...but i was thinking head gasket also but there is no coolant loss at all....zip zero nada

 

Hmm, that's weird is it thick smoke? Is there a sweet smell when you get the throttle after boost?

 

turbo leak or piston rings or put an oil catch can it will help u to fix that thing

 

White smoke - coolant
Gray smoke - oil
Black smoke - gasoline

It sounds like you could be sucking coolant into the engine when you are in a high vacuum condition. Check your coolant for an oil sheen. You may have a blown head gasket,.

 

If it is def white smoke, you'll need to do a compression and a leakdown test to check the head gasket.

 

Yeah. I think is your headgasket going out. Any overheating issues?

 

Yup white smoke means water/coolant. It has to be burning from somewhere so are you sure that you are not losing any? Is it possible that water get in your exhaust somehow?

 

Just my .02 cents but the other day this same thing happened to me when i went to fill up with fuel. company put diesel in the pump instead of the e85 so my car blew out smoke like a champion. Is it possible you got bad fuel?

 

Ok...just finished the compression test and this is what the results are...
Stock Compression pressure should be around 145psi

and my values were
152psi
134psi
153psi
146psi

honestly i think my rings are perfectly fine...even the one cylinder with 134psi that to me should still be good seeing that its a 10psi drop.....the oil level is still full.....the coolant level is still full and there is no oil sheen or contamination what so ever.......i've filled up at 3 different gas stations and still the same thing.......it blows out the smoke on deceleration which would lead me to believe its my valve seals but my oil is still full....i did a oil change and drove over 600miles and its still at the full level........
