Hi, welcometomyturbodies. It really depends how much oil is leaking. They always blow a bit of oil through and the pipes for the turbo are normally coated inside with a bit of oil but if it is a lot and your oil level is dropping excessively then it could be a problem. The intercooler can gather oil as it is low down and some may get trapped in it. If it is like a cupfull I would be concerned.:)

You're probably better to wait for someone else to advise on that one as I've never had to do that yet. I like the idea of a challenge of a rebuild but better to wait on other opinions as there are more experienced people than me on here and I would ask them first before I attempted anything.:)

I don't like rebuilt turbos because the quality can often have wide variation. Some are good, some are bad. A rebuilt turbo where they change the entire center section with brand new section from manufacturer is fine since the cast iron housings doesn't wear much. I haven't seen OEM TDI turbos with this option though, only new complete turbos.

How much oil is leaking into the intercooler? If it gets really bad you could have an engine runaway- see here for details: http://www.myturbodiesel.com/1000q/stop-runaway-diesel-engine-how-to.htm . Otherwise if it's minor you may still be able to drive like that. A little bit of engine oil in the intercooler is normal because oil mist settles in the low spots.

Just monitor for now, 10 grams doesn't sound like a lot, is that enough to wipe up with a single paper towel? A little dribble of oil is normal. A cup full is not.

It sounds like your turbo broke quite quick, can you not get a second hand one where you are? Do you feel confident in repairing it yourself? I only ask because they sound quite tricky to fix and you might need some special tools. Maybe if you are going to do it yourself you could take some pictures and show how you did it.:)

No i will not repair my self, i will take out of the car and i will send the turbo at the specialised turbo repair shop. They have High-speed turbo balancing machine, if you want i will take pictures of the removal of the turbo and you will see the damage of the turbo itself.

The aluminium impeller on the compressor it's in bad shape tomorrow im taking the turbine at the turbine shop will see what will happen :ugh removal of the turbo was very easy.
Today i've taken my turbo to the turbo repair shop, whole center section will be replaced and will be ballanced on turbo balancing machine, and the variable geometry will be set on the balancing machine, the engineer who works in the shop tell me my turbo will be like brand new when i put back to the car i will see the results tomorrow. I will post pictures of the repaired turbo, and it cost me 380 euro.

Sounds good, did he say what he thinks may have happened to your turbo?
The oil seals in the turbo were gone, and the oil from the intercoler went into the engine and ignited then happen engine runaway and the turbo was making more than 200 000rpm. That destroyed the turbo.
