Rebult turbo pouring oil out of tailpipe

robertyateman · Jun 6, 2014

So i cleaned my intake manifold exhaust manifold and egr and cleaned turbo put it all back together today and when i started it up oil was coming right out of my tailpipe at a pretty fast rate. Not sure if i might have hooked something up wrong but the turbo was in working order and i bought a new vnt. PLease help i need to drive up to work with it in another two days

did you drain your inter cooler??

Was this your own turbocharger that you cleaned? If so, sounds like you tooefed it when you cleaned it.

You have basically 4 choices:

1) buy one from the dealer
2) buy one from a vendor like Boraparts or IDparts and have them overnight it
3) get help from a friend that happens to have one laying around
4) find an amazingly well stocked junk yard and get one from them

Of these, 1 and 4 I'd probably try to stay away from. Good luck with the rest. Pretty much, if you have a turbocharger that leaks that badly, then you need a new unit. It isn't something you can fix yourself.

Sorry...

yes it was drained. I cleaned everything . I took it all of an 01 and mine is a 99.5 so I have my turbo here too. I cleaned it all because my vnt broke on my last one.

CNGVW · Jun 6, 2014

I would pull the turbo boost hose off at the turbo. Check to see if you have any free play ( up and down movement of the shaft) and how much oil is in the compressor side.

A engine with a plugged up intake and turbo not making boost can hide some inter problems.
Like a lot of blow by, so check to see if there is blow by coming out the top breather.
if there is it could be a broken ring or piston problems.

If it is the turbo it could have a bad seal ( they are like little steel rings on the shaft)
or the oil return line is plugged. This will force oil right by the seals.

What did you actually do to clean it? Just the vnt? Or did you take the whole housing apart and pull out the shaft?

robertyateman · Jun 6, 2014

Took the shaft out and everything cleaned with easy off and sanded it.

robertyateman · Jun 6, 2014

Thanks so much cng ill try checking the outlet port and if not ill tear my turbo oiff and check the seal

"took the shaft out"

what did you do wth the shaft seals, and how did you rebalance the rotating assembly on rebuild?

robertyateman · Jun 7, 2014

Didn't really rebuild just cleaned n bought new gaskets n bolts. Stupid me didn't even notice any washers. Bearting in the shaft seemed to have no play so I didn't replace inner rotating shaft

robertyateman · Jun 7, 2014

I took it off my car from underneath thismorning the big metal ring behind the turbin has allot of play for some reason. i need to get my hands on some cutting torqes to get my other turbo apart then im going to switch it in and try that. Hopefully all goes well

robertyateman · Jun 7, 2014

Took apart the other one and were i thought the metal seal was loose its also loose on the other one so im guessing thats how its suppost to be

carbonbl · Jun 7, 2014

Don't take this the wrong way, but sounds like you might be in over your head and should send the turbo to a pro for rebuilding, or get a good used unit that has never been disassembled.

Here's some information about turbos/rebuild kits that might indicate what is going on:

Bummer, sounds like you did something wrong for sure. If you take the shaft out you need to mark up the compressor wheel, nut and the end of the shaft too so you can out them back in the exact same spot to keep the balance.

Metal seal? You mean the big domed looking washer? That's a heat shield thing for the back of the vnt, has to go the right way round or it's loose. The seals are actually like piston rings in a way, they kinda look similar but smaller, there's one at each end.

I should have pics around from when I rebuilt mine but can't find them just now.

robertyateman · Jun 7, 2014

carbonbl I gotter I dont know why you lost hope so fast. I found a rubber seal on the middle part of the shaft thats attached to the two rotors and it had a crack. So i used part of my original turbo and installed it onto the manifold while attached to the car:/ everything seems to be working. Exept i couldnt get two of the bolts into the rear of the turbo im going to have to manufacture some wrenches up.

The only thing left to do is record my turbo with my vagcom, witch i'm unsure of how to do make sure i'm not over boosting.

Thanks for everyones help again you guys got me threw another project lol

Seatman · Jun 7, 2014

What rubber part? There's no rubber inside the turbo other than the gaskets for the housings?

DPM · Jun 8, 2014

perhaps that's the piston ring he's describing?

CNGVW · Jun 8, 2014

I rebuild turbos in house and some times those little parts fall out.
Do not use that turbo if it comes apart it could junk your engine.

You most of lost one of the seals it is like a piston ring but the size 1/8 round.
Just fine a good turbo now.

robertyateman · Jun 8, 2014

Last thing my turbo and maf are staying the same at all rpm the maf is about 420 give or take 50 and the turbo is 1000 give or take 100. Not sure if i just need to adjust my wastegate ??

Seatman · Jun 8, 2014

Doesn't sound like the waste gate is moving at all, you sure it's connected?

CrustyOreo · Jun 9, 2014

Sir please step away from the vehicle.

Kevinski4 · Jun 9, 2014

Your turbo doesn't have a wastegate. Did you actually drive it or just rev it in neutral while watching the data?

Gotta agree, rebuilding turbo's isn't child's play.

Seatman · Jun 10, 2014

It's not childs play but sometimes it takes a bit of a disaster to learn ha ha

But they are pretty simple really, just need to take care and not charge on without any knowledge, also be sure to have things balanced. The main assembly is pretty straight forward though, not a lot of parts involved.

They aren't simple and shouldn't be treated as such, ESPECIALLY a diesel where a failure can result in runaway condition causing engine damage and/or property damage or even killing someone if you can't stop the car.

Turbos are just metal, no magic involved.

Now, computer controlled things, those are magic.

ETA: did you poke a wire through the drain passages? any kind of backup of oil and these things'll leak.

They're VERY simple, I rebuilt mine a while back and it's tuned, never burns a drop of oil (engine oil) boosts spot on, very smooth.

I did say they do need to be balanced and that's the important part, also helps if you put all the parts in the right place when assembling.

But I don't think the fault is with the turbo in this particular instance rather than someone diving in without paying attention and reading up some simple info first. Common human error and one way that we often learn.

I just wanted to let everybody know. This was simple it doesn't take a rocket scientist. It was leaking oil because the seal was ****ed on the turbo probably from me cleaning it. So i put the other turbo back on all cleaned up with a new actuator. I was getting no boost and a steady reading of 400-500 on my maf because my actuator rod wasn't adjusted right. I just re adjusted it and now everything works fine except that my maf is reading higher then the "maf actual" number by about 200 and this is because my egr valve is defective somehow but I don't really care because i am getting proper boost and everything else is running perfect ! So for those that were negative and not helpful you can read between the lines.

Pretty smug for a guy who got lucky in that he screwed up the turbine seal rather than the compressor seal.

not being smug. People that arnt helpful and are negitve shouldn't comment. And I might not have ruined any seal. It could have already been ruined it was off my parts car I thought the turbo was good on. Not sure if it was leaking oil out the turbo because I only had it running forn 15 mins before I parked it.

nice try though.
