Well, I'm happy that I'm boosted now. But there are still a few kinks that I'm having.

Let's start off w/ the turbo..

It's a used T3 w/ Deltagate WG. The turbo "looks" to be in almost perfect condition. It boosts fine and holds boost all the way but when I come to a stop, or even driving at low speeds, I notice smoke coming up from under my hood. When I'm driving 60mph+ I'm assuming the air just blows all the smoke back and when I come to a stop, I notice that the car will smoke.

When I checked to see, I noticed that it was coming from the DP (open DP). My oil feed line is fine. There are no leaks. My return line is fine. I don't think it's too low. I checked coolant and it was fine. I checked the chargepipes, and I didn't notice any oil.

One thing for sure, I can definitely smell the oil burning while I'm driving. Keep in mind, this all happens when I'm not even boosting. I kind of have a feeling it's the oil seal, but I'm not too positive on what all the symtoms are.

Another thing is that I'm using 5/30 oil. Could that be a possible problem?

If you guys have any exerience or knowledge in this matter, it's greatly appreciated.

Thanks in Advance.

 

Check your valve cover breather. Do a pull or whatever you need to do to make it smoke again then actually look under the hood to see where it's coming from. If it is the valve cover breather do a compression check and cross your fingers

 

it's not the breather. Smoke is only coming through one part, which is at the DP..

One thought came to mind is that maybe I have too much oil in the motor and the oil might be too thin as well..

 

Maybe too much oil pressure to the turbo and it's getting past the seals. Maybe try getting a restrictor or check to see if your turbo is blown.

 

I'm gonna change the oil first to see how the car will act. Anoter posibility is that I might have too much oil in the motor (4 quarts) and my oil return flange is a bit lower than what I originally planned it out to be. . could that be a problem?

I failed to mention this, but probably

 

too high oil pressure, backed up return, or bad turbo seals.

 

Thanks Dustin! I HOPE if anything, that it's backed up return line only because I know the flange is a it lower than how I wanted, plus the fact that I believe too much oil is in the motor..

 

Too much oil in the motor is not going to cause this. Oil only gets to the turbo from the feed line, which gets regulated pressure from the oil pump, which is indifferent to oil level unless you are out of oil

 

Sorry.. Let me clearify it again... lol...

What I meant was I think that too much oil is in the pan. And since the return flange is lower than what I had planned, the return line might be restricted..

Could that be a possibility?

 

Well ... the oil level would need to be as high as the bottom of the turbo then... and that's usually pretty high depending on your manifold hehe.

How much oil are you talking about? 4 extra quarts?

 

LOL..

I just changed my oil using Mobil 1 full synthetic.. I used 3.5 quarts of it. It doesn't smoke anymore! woohooO! thanks for the help guys..

 

it's full with only 3.5 quarts?

 

I'm not sure if 4 quarts will be too much. Some people say it is, some disagree.. what are your thoughts?

 

I always put 4 quarts + a "little bit" in B series motors.

Does the dipstick show full when the car is warm with only 3.5 quarts in there?

 

are u still using 5/30?

I think Im having the same problem as you, I may try to do what u did to see if it helps, cause I think either too much pressure goin to my turbo or my flange on my oil pan is too low....

 

I'm having the same symptoms...

 

Man.. OK.. So here's the stupid situation now.

It's still smoking. Odd thing is that it ONLY smokes when I drive it regularly at "cruising" speeds. If I make the motor spool, or drive it in full boost and come to a stop, it won't smoke.

My friend drove it for me yestersday boosting through 3rd gear.. VERY little smoke.. Nothing big at all.. After that, I thought that the car was ok so I took it home on the freeway. As traffic came to a stop, it was still fine until maybe about 5 min into traffic, I was only in 1st and 2nd gear goig really slow. I would step on the throttle lightly but when I'd come to a stop again, the smoke would come out.

I believe my return line is a bit low so I might want to redo it.

Is there a posibility of having a chipped ECU can cause more oil pressure going to the turbo? If so, I think a stock ECU might be handy and even possibly a stock ECU with an oil restrictor...

What do you guys think?

 

ttt

 

If the car is smoking, it's a mechanical problem. The ECU does not control or affect oil pressure. Oil pressure is a result of engine RPM and oil temperature/viscosity alone.

Try an oil restrictor to see if it helps. It should. There is a distinct possibility that the seals in the turbo just aren't in that great of shape.

 

ECU is not your problem. I'm still gonna say it's your oil feed line (need restrictor) or blown seals

 

Ok.. Thanks.. As you guys have helped, it's helped me narrow the problem down to 2 things that could be wrong..

Oil Seal - However...There is no sign of any oil in my charge pipes or around the turbo. It's a possibility, and I hope it isn't, but it's still a possibility.

Oil Return Flange is too low - I'm almost pretty sure this could be the cause. I've been searching H-T all morning for pictures and when compared to mine, a majority of the pictures that I have saved have their flange almost or about an inch higher than where mine is. There is no kink in the return line and it's only going downhill.. but the flange is just too damn low.. just great.

Opinions?

 

you say none in your compressor or charge pipes... but have you taken off your DP?

also something to consider, VW's have there oil return at the bottom of there pan... i dont think that is the issue in your case.. sounds like a seal issue to me.

 

No oil in my pressor or charge pipes..

I'm running an open DP and no signs of oil at all..

 

well if the seals are bad and its leaking into the exhaust hosing alone the oil will burn before it get to the DP so you wont be able to see residue but it will smoke
