Oil leaking from tail pipe

I have a vanagon with a 1.9TD. It is just a few thousand miles old (rebuilt everything)
There is oil leaking out the exhaust and smoke when taking off from a dead stop. When driving, there's no problem.
When I removed the exhaust, oil was leaking from the turbo.
I was told this was a sign that the turbo was beginning to go. I was also told the that the turbo was "turned up too high".
Is this a sign that the turbo is on the way out?
And how does one adjust the the turbo to "turn it down"?
Thanks for your help,

Yes, the bearings in the turbo are worn. You can get the turbo rebuilt. If your wastegate is seized it will cause the turbo to spin too fast and the oil supply will not be able to keep up. Or if you have a manual boost controller the max boost is too high. More likely the wastegate is seized.

So, the turbo is toast or can anything be done to prolong the inevitable (replacement).

It's toast. In fact, you could grenade the engine running a leaking turbo. If enough oil leaks out of the compressor side of the turbo, the engine will start accelerating uncontrollably as it burns it. It's called a run-away and once it happens there is very little you can do to stop it aside from popping the hood and frantically putting your hand over the intake opening as the engine spins out of control in your face.
Then a rod will go through the block and hopefully it won't kill you.

so when you say you rebuilt everything, you mean everything but the turbo??? i think its time you look at buying a new turbo. there were some nice K03 turbo's in the for sale section a while ago listing for about $400. i think thats the going rate for them. they are perfect for a 1.9TD as they spool almost instantly.

The thing that doesn't make sense to me is why it doesn't do it at a higher speed I would think it woud be worse but obviously it is the turbo though

How do you stop a runnaway turbo if lets say you're doing like 65 on the interstate? Do you just apply the brakes and leave it in high gear and hope to slow down enough to stall the engine. I wouldn't know of any other way. I've had them run away from excess crankcase pressure but it never lasted too long. The turbo has a lot of oil to suck though till it gets full

How do you stop a runnaway turbo though if you're doing about 65 on the interstate. Do you just put on the brakes as hard as you can leaving it in high gear to hopefully slow down enough to stall the engine, I wouldn't know what else you could do. I've had runnaways from too much crankcase pressure but it never lasted too long but the turbo has a lot of oil to suck up before it runs out.

That's about all you can do. I sure as hell wouldn't try to block anything with my hand. :shock: Hopefully you don't have an automatic because you won't be able to stall it. :lol:

I wonder how a butterfly in the intake elbow like a hand choke settup would work if it did it while you were driving," just pull the knob" :lol:

No I wouldn't use my hand either, I'd be using it to wipe my ass about that time, doubt if I could reach out there from behind the wheel that far anyway. :lol: Or I could just put the damn thing in neutral, climb over the seat and lay on the back floor and wait for the explosion or the crash, whatever happens first :shock:

Brakes are engineered to be strong enough to stall an engine. SO if this is happening just lock up the brakes as best you can. That's my advice anyways. Maybe do it gradually, try and control the acceleration. Probably need new pads and rotors after that along with many many ... many
other things.
gotta be in gear too don't forget. Scary situation none the less.
on the same topic (sort of) How can you prevent the turbo from not seeing enough oil if you have the boost turned up?
Is that was a 36mm oil pump is for?

Along this same line, how do you know if your turbo is leaking oil on the compression side? (In a car with a long exhaust, unlike a Vanagon) I get some oil back down the intake duct, but since my crankcase vent is tee'd into the intake, I'm guessing it's blowby...
Or maybe more broadly, what's the best way to assess your turbo's health? If it matters, mine is a K14.
