Smoking at odd times!!
Smoking at odd times!! Ok so i go rip around town havin fun adn i hit the highway. Go fast for a bit then im comin up on my exit. I am goin pretty fast so i use both the brakes adn the engine to lower my speed. Went from about 100 to 0 but not beating the **** outta the motor adn lettin it drag from 6k in each gear. So when i finally get stopped i rev the engine and a good amt of smoke comes from the exhaust! I am unhappy figuring that i broke something. I get to the next light and rev the engine again seeing how bad the smoke is. Yet there is none. So i go to a parkin lot and have the g/f rev ti some while i stare at the exhaust tips to look for smoke. None. Now im preplexed. I go and try to recreate the incident. Decelerate using the engine and the first time i use the gas at all weather its revving it or pulling away i get wuite a bit of smoke. I tried this a couple times adn realized that i dont even need to accelerate hard at all. I can jsut be puttin around adn then decelerate using the engine and have a smoke show at the end of the exit ramp. YAY. I want to reiterate that i am not using the engine alone to stop adn i am not letting the engine start to decelerate at 5k in every gear. When the revs woudl be about 3500 in that gear i tap the gas to match the revs with teh speed and let the clutch out.
Hope yall can help me out!

Well I can tell you this. If your going to use big words like "preplexed" at least spell it right. 
Just messing with you.
Sounds like you might be getting oil back up the drain tube when you left off the gas. Or it could be the way your PVC is setup. Thats why I asked you how yours was.

That would be my guess. Oil is probably backing up in the drain tube on hard deceleration.

As far as the pcv system it is totally stock. I was talkin to BOOSTNSS, derek, on friday adn he asked me what i did with my pcv system and im like....WTF is that? I had never heard of anyone doin anythign with that before and noone had mentioned it to me. I went and looked on teh side of the TB today and i do see the large hose that is hooked to the side of the TB. What do i have to do to eliminate that? can i jsut disconnect the hose off the TB cap the line ont eh side of the TB adn call it a day? Is there any sort of 1 way alve on that line? Have i been pressurizing the crankcase everytime that i get into the boost? Thanks for hte help guys!

PS i have had this issue for YEARS but since i never had smoke at throttle i never cared. Still no smoke at throttle but Im pushin the car a little harder now so i wanna figure it out. Thanks.

It sounds like a stem seal issue to me. Do you get a puff when you cold start the car as well?
As for the PCV system, you need to sort that out because you are pressurizing the crank case without some sort of check valve setup that prevents boost.

Well why the hell didnt anyone ever tell me that that is how the pcv system works under boost. Prolly using alot more of the turbo then i should be if i am shooting al that pressure into the crankcase. Ill be disconnection the PCV system tonight, capping the TB, and throwin a catch can under the pcv hose. thanks for the help guys!

Made a ton of sense John, I'd bet thats what it is, decelerate hard and the oil backs up for a second and goes into the dp and voila SMOKE SHOW. Turbo sits just above the pan and his line goes from the bottom of the turbo to the front of the pan just under the crank pulley so I can see it backing up a lil.

But like 99SS-T asked about the PVC system is what I like to know to. What should I do to it before I run the car?
Theres one large tube that comes off the TB on the passenger side?
One small one on the TB that goes to the passenger valve cover?
One tube on the back of the passenger valve cover that runs to the drivers side into the PVC valve?
I plan on putting a breather for the oil cap what else should I do to those lines I talked about.

Lol i totally forgot i made this thread. I am gonna cap the end of the metal hose that comes off the side of the TB and goes to the passanger valve cover. I think that should definatly help my smokin problem. I am gonna figure out some sort of catch can for the hose that is comes off the valve cover. I definitly think taht this is a major contributer to my smoke. Will let ya all know later tonight when i finish. Thanks

Well i rerouted the PCV and capped the line off the TB and it substancially cut down on the amt of smoke. There is hardly any adn i really have to try hard to make it do it now. It is liek when i had it pre turbo. There was only a little smoke after deceleration. Thanks for all the help guys!

Glad to hear that you got it taken care of. It was probably pulling oil from your PVC system. Next time I meet up with you, I'll have to check out your setup to see what it looks like.
