ok well heres my problem. my car has decided that today it wants to smoke. i dont really know why, dont know why it has to be now, but today it happened. now the question is, whats wrong with it?

ok 1st off. Turbo B16 stock bottom, unknown milage. 48/60 T3 log mani, 2.5 inch DP to 3" totally unresticted catback (new yesterday, just built it). the car is tuned on crome pro by xenocron, so im confident in the tune. i run a catchcan (it works, so i dont have to explain how i have it run)

im thinking its my turbo seals. i dont run a restrictor, but my line is -3an so i shouldnt need one correct? it smokes at idle and i THINK on decel, but i cant tell. i know that every time i come to a stop, i get a plume of smoke that comes from the exahaust. im gonna pull the filter tomorrow and check out shaft play and to see if i have any oil in my charge pipes (though i shouldnt, causemy turbo doesnt shoot down, it shoots up)

i did a compression test as soon as i saw the smoke and it was 185 190 185 195, so thats fine. i also had a little smoke coming from my valve cover breather (i run a tube to the ground) and a little oil on the end of the tube. anr my ringlands smoked too?

ALSO the car felt like it was down on power today compared to last night. would the turbo blowing out its seals hurt its efficiency? BUT it was 45 degrees last night and CLEAR and today it was 70 and overcast/humid.

i know this was a long thread, but i need someones help here

i whould say by by seals, just rebuild that **** and get a restrictor valve

thats what im thinking...... grrrr. anyone know a good place to get a set of seals??

BoostedBSeries

anyone else have any suggestions?

Wouldn't be ringlands. Look at your compression. It is more of a D-Series compression check though, but I still would say its not ringlands and the fact you run a catch can to help? Nah, I doubt it.

I have NEVER had a problem with needing a restricter. Each car to it's own I guess. We are all assuming it's BLUE smoke, am I correct?

that ---- happened to me. Shitty gas and a little boost spike caused my stock z6's hg to take a ----. Smoked at idle and when you let off the gas. Eventually it smoked alot. I thought it was the ringlands or something too. At least thats what i told myself so i could build my engine.

-3 AN you dont need a restrictor.

BoostedBSeries

yup, def blue smoke. and i know the compression is a little low, but it still seems within the normal range. im thinking about going out in a few mins to see if there is oil in my charge pipes and check and see how much shaft play the turbo has

when i popped 3pistons in my gsr last yr, my compression was still 185 across.

but it was slower and smoked. leaky seasl in your turbo shouldnt account for lack of performance smoke out of the valve cover hose is not an optimistic sign

BoostedBSeries

yeah i know. im leaning towards broken motor. but i still dont want to rule out something else

I bought that turbo brand new and didnt even have it on my car for 10k. I doubt it would be the turbo with those few miles on it. But check anyway I guess
