Help! Smoke on decell

Good morning

I have a problem with my 2000 X. It runs fine with the only problem being it will smoke out the tailpipe only when I decellerate. Its a fairly large plume. It seams to be intermeadiate-coming and going- and worse when warm.
MODs: turbo back 5" ex, open intake, edge tuner. It smokes on all tunes including stock

Ideas? It is sucking oil out of the PVC?? Out of the turbo?? Can it??

Stumpped! It wifeys rig and she wants it fixed and I don't want to go to the stealer ship!

PS no codes on my scanner!!!

Thanks for any Help
Shawn

How about just disconnecting the PCV system at the valve cover and see if that solves the problem? If it does, then you know you have a blockage somewhere in that system and you need to find it before you blow seals out of the engine. If it doesn't solve it, then I am not much help to you. It would seem that it could be a turbo problem though.

What color smoke? Is your air filter clean? If it only does this on a tune off the Edge, that may be your problem.

It is possible for the turbo to be leaking oil. Is there oil in the tail pipe? You should be seeing the smoke while accelerating. What color is the smoke.

If the turbo is leaking oil into the intake you should see oil in the pressure side of the pipes and air/air cooler. Also check down pipe for oil.

Thaks again
I now have oil coming out the tail pipe and I will check the inter cooler pipes to see evedence of oil.
how difficult is it to reseal the turbo??
Can I do it? I'm fairly adept at motors and I'm sure I can remove it.
or should I get a newly rebuilt unit since mine has 160K on it??
Thanks

Easy way to verify if the turbo is shot is to remove the intake boot and move the shaft.
It should have almost no movement at all side to side and none in and out.
