300tdi Dumping Oil out of exhaust.

Just come to a friends to look at there 300tdi that's loosing oil.

Now while looking for leaks around the engine, some one told me to come round the back and long and behold a pool of oil from the exhaust. This only took a few minutes with the 2 high revs.

Now I was thinking head gasket, but then I'm seeing posts on turbos, rings ect so it's proved to much info im confused lol.

With it dumping so much oil so fast I wonder if that might narrow the problem down.

I've included pics to illustrate the amount.

Any help would be appreciated.

Thanks

Not an expert but as an idea...

Check the oil return pipe from the turbo to the engine, could be blocked causing the turbo to suck the oil into the exhaust system?

Probably leaking from the turbo bearing on the drive side of the turbo - if it was leaking on the compressor side your engine would runaway

Tip: remove the turbo outlet hose (elbow) from the turbo and feel how much freeplay you have in the turbo bearing (side to side movement) on a good turbo it won't move

If it's worn as above you can buy a kit on eBay , the internal gunbins of the turbo new for around£180

Forgot to add: if when you remove the turbo outlet hose (elbow) from the turbo there is a fair bit of fresh oil in there - don't use the car/run the engine til the turbo has been sorted out!!

Cheers guys appreciated , well I'm nipping back round this afternoon after work, and I've told them not to drive it. I'll give the turbo the once over. I've seen some second hand turbos for cheaper or is it better to just recon the existing unit

You can get a good secondhand turbo on a manifold so its easy to change them over, replacing the turbo cassette is a bit more difficult......

That's up to you if your good with spanners and c clips your be fine better than an unknown postal job if not then the latter will be fine as there usually checked to save wasting people time good luck

Right here's what the situation the oil pipe from the turbo to the intercooler (elbow pipe) feeling inside the hole I can't feel anything but the inside of the pipe had a large bulge nearly blocking the pipe itself (guess that's due to age) but if I remove the air in on the turbo and wiggle the little fan it shakes more than a Hawaiian hoola girl, I take it that's what shouldn't move?

Nope - looks like it needs replacing mate!!
It should spin round but you should not be able to pul in/out or move it side/side

turbine will move a bit as shaft sits in a bush and is supported by oil pressure when engines running ,yours probably sounds too much

Be aware that if the engine starts to feed itself from oil in the turbo that the engine will runaway - the only way to stop it is to stall it - before it wrecks the engine!!!

Don't use the car or run the engine until its been replaced!!

Yes, it shouldn't move much at all.

If you replace the innards you should really get it balanced by a proper turbo place. I'd just buy a second hand turbo!

One area of confusion about balancing is component versus assembly balance. Turbocharger rotating groups are made up of several component parts that are assembled to make up the rotating assembly. Of these components, only the turbine and compressor wheels are component balanced. Balancing of these components is critical, and must be done prior to assembly. The axial thrust spacers and compressor locknut are not balanced, and the mechanical fit of these components are subject to machining tolerance limits. When these pieces are mated a certain amount of “stackup” unbalance is introduced into the completed turbo.

Thanks guys, she's all fixed and back on the road today. Yet to let the owner (auntie) take her out. There is oil and smoke still but it's not dropping when checking from the dipstick, so it has to be the left over in the exhaust.

Thanks guys once again!
