Dripping Oil from the Exhaust

[Ruddy]

I have a 2005 Jetta4 1.9tdi AHF engine code with 290 000 km. Had a turbo problem, shaft snapped while driving. I managed to get home,parked the car wasn't leaking oil even when I started it a few days after the incident just wanted the battery not to go flat(didn't drive the car,let idle for about 5mins and switched off).
Then I eventually took off the turbo to access the damage,it was bad the turbo shaft was split in two. I started the car without the manifold started and I hooked back the manifold after I took off some photos off the turbo to find a replacement. Then on two occasions I started the car with the same broken turbo that was when oil started dripping off the exhaust pipe. Managed to find a replacement turbo,bolted it up and still it's dripping oil off the exhaust pipe,it's not smoking not even little smoke to notice. It's revving well enough to confirm the turbo is working,can rev to 3000rpm at idle.
Can somebody point me into the right direction so I can know where exactly my problem could be.

Turbo oil feed line compromised?

When your turbo snapped you ended up dumping oil into the exhaust…. This has happened to me and family fleet twice.
Once you get everything back to you need to find a desolate place or at least not too populated and drive the car like you stole it to burn off the accumulated oil in the exhaust…… this will take about 15-20 minutes with a large cloud coming out exhaust.

Yes I did put a good turbo after, started the engine let it idled for like 10mins without revving and it was all good and dry but after revving it started dripping out oil again till to this day. I'm actually getting confused if it's the excess oil from previous leak or it's leaking into the exhaust reason being the amount of oil dripping out the exhaust it's too much. Not like dropping but pouring out from the exhaust

Would assume it's residual from turbo fail.

 

[csstevej]

What BOB said ….its all residual….. plus you ran it several times which is still pumping oil into the exhaust.

I would be checking the oil level daily.
If it's not going down then I would think it what's stuck in the exhaust somewhere.

when I blew the turbo on my 2001 under warranty the dealer replaced the turbo and the cat and they warned me that I would get oil out the pipe for a while and this was normal.

The lack of smoke to go along with the dripping oil is a little out of the usual, post turbo-fail, but it may be that it's lodged in a cooler part of the exhaust system and your driving routine never gets it hot enough to smoke?

I'd say the most important question is above: is the car using oil as well?

If not, it really is most likely just residual oil from your turbo fail. In my case I had to spend an hour on back roads doing spirited driving (to keep the EGTs up) before all the oil left the exhaust system.

however, it could very well still have stuff clogging it up more than is ideal, as well. better to just knock the cat guts out IMO

I can today confirm that it's not residual oil, topped up oil yesterday started the car and it idled for more than 10mins as I didn't wanna drive it not knowing whether it'll run out of oil while on the highway. Fair enough,revved it yesterday seemed to have stopped leaking a think cloud of smoke came out confirming the exhaust pipe was getting dry. I reversed the car and parked it,next morning started it hoping to run a stretch with it and surprisingly oil started dripping out again,checked the dipstick level had gone down. So,my concern is do I suddenly have worn piston rings or worn valve seals?Before the turbo scenario car was running perfectly fine no smoke or any bits of oil droplets off the exhaust. Can someone please shine the light for me. If allowed I can attach a short clip of the engine running

Where'd you get the turbo?

Other note: A restricted return line will cause this as the return must entirely without restriction. I'm assuming you know the return out of the bottom of the turbo back to the pan is entirely-clear, yes?

 

[Ruddy]

Turbo came off a donor car, previously running. The return line is clear not even kinked.

 

[Vince Waldon]

Double-checking that by "clear" you mean you've unhooked it, draped it into a catch pan, and ran the engine briefly to confirm full oil flow?

I only ask because there's a small possibility the previous turbo shaft cracked in multiple places, and a small chunk could be lodged in the return line, which you wouldn't detect by external visual inspection. And/or something fell in during the turbo install, or was dislodged from the replacement turbo.

Long shot, for sure, but whatever is going on here is already a long shot.

Cleaned everything oil feed line blown out with compressor air. Disconnected the line off the turbo cranked to check if oil is coming through,yes it flowing out normal.

When idling it's ok only drips when I rev,it drips for about 30-60seconds then stops till i rev again

That sure sounds like a collection of oil from the original failure. Watch oil level; the stuff collected in the exhaust piping should get expelled. A run up to temp, and then a ride down the highway in 4th gear should help convince the puddle inside to shrink.

Thank you will get back with a respone with some results when I get back from a drive
