Smoking between shifts

[Goobdog]

My car is smoking in between shifts but only when the turbo is spooled up. If you drive slow and let it not build boost it doesn't smoke, also it doesn't smoke at wot only when I let off the gas to shift. The car doesn't smoke at idle either. Would this be the oil seals in the turbo ?

It sounds like it could be the turbo seals. Pull the LICP and check for oil build up.

I would start searching for a new turbo, your seals are bad, this just happend to me and my computer was down for a week becuase of the hurricane, so i had to find out all out on just blowing my turbo till it couldnt push anymore. I just got a 16g .. ill be waiting for install.

yeah, it's more than definitely your seals gone bad, same thing happened to me back when i bought my car, started runnin too much boost, and the ol t25 didn't last anytime, but right now i'm in Iraq, getting me a pretty big stockpile of parts going, tryin to do everything right the first time! gonna just build my 7bolt with a rs49t, and in the mean time get a 2.3 6bolt built , and either run a gt35rl or full garrett, i already have just about all the supproting mods, just debating between fmics and which tuning program to run, but good luck with ya car

Best buy is an EVO3 16G turbo.

I agree, turbo is goin bye bye.

some black smoke on a car making more then stock power - esp w/o a CAT is normal.

First thing first what color is the smoke? A lot of you are jumping into conclusions rather quickly without all the facts.

Yup it is

My question is this is the BOV recircurlated or vented to the atmosphere. If its vented that might be your problem right there.

 

[Goobdog]

The bov is recirculated of course. This is my other car it has a big 16g not the 14b in my profile. The smoke is white, like I said when I shift AND the turbo is spooled up is when it does it. It doesnt smoke at startup and it doesnt smoke if it doesnt go into boost which is kind of hard to do since it spools up so quick. Also when I took the clamp off the center section to take it out of the exhaust housing there was oil built up on the bottom of the housing.

Edit: Im pretty sure I know what killed it. I was having some problems with detonation ( bad gas ) and it was blowing headgaskets left and right so when it blew the gasket I would be in boost and had to shut the car off immediately.

That would usually cause you to fry your bearing, not blow the turbo seals....
You need to pull the LICP off and look for oil... that will let you know. Otherwise run a compression test to test your valves and rings.

 

[oldman]

If you're sure it's not black smoke and you found oil at the turbine housing (make sure no oil at the inlet), then it probably is the turbo seals.

edit: inlet refers to exhaust turbine housing inlet not the compressor housing.

 

[Goobdog]

The smoke is definately white . I did a compression test and its 185 across ( cold ).

 

[mattspyder]

i have the exact same problem!
but now it smokes at idle. pretty sure its my valve seals. but im 100% sure.
