just get a compression tester and test it yourself. It's not that hard.

Now from what it sounds like. You're burning oil... and the smoke coming out of the exhaust is actually blue, just a really light shade.

so you're looking at either valve seals or piston rings for the most part. A compression test will tell you which it is.

 

^ Yup, turned out being th rings. $3000 to fix it. Going back to stock!

 

well you're going to have to dissassemble the block to replace the rings anyway. Might as well throw some stronger pistons in while you're at it at least.

sux you have to throw down on that large of a bill. But might as well make the best of it.

edit: on a side note, a brand new engine is gonna cost you 2500...

i just dropped my car off yesterday for the same problems, coolant tank has been re-filled 3-4 times in the past 3 months,

now it idles like it has parkinson's and white smoke plumed out of my exhaust yesterday.
I dropped it off in the overnight / Sunday drop box, hope to hear from the dealer soon.

 

So what was the diagnosis?

 

Bump.


Has this happened to any one else?

 

sorry havent logged in, in a while

Bad head gasket, warranty covered everything 100% including my rental for a week.
had to send the egine head out to be inspected for damage, but it was ok...


i also had stage 2 installed, and they said nothing about it....

 

Isn't white mean a headgasket is shot or the block is clacked so you are evaporating the coolant

 

Hey guys here is a quick update for me...
#4 piston was F**ked and $4200 and 6 om=nths later she is back to normal.

 

Fooking A. WTF you been driving while the car was under the knife?
