Oil in turbo air pipe

rayrayt6 · Post by **rayrayt6** » 20 Mar 2011, 18:16

I have a 2000 s80 t6. I noticed a oil leak leaving drips on the ground. My oil cap also seems to leak a little but no drips. I went to take the air pipes off the top of the engine and the one that goes to the drivers side turbo(on us cars) has a little oil in it. Why would that be there? Is it the pcv system and is there a walkthrough on fixing it?

I checked to see if there was pressure at the oil cap and fill tube and there was not so now I dont know what it could be. Any help would be great.

I have the same problem, but more extreme than what you are describing.

The turbo side of the air hose is absolutely caked (from around the PTC on back) with what I can only describe as petroleum-based gunk, as is the impeller inlet itself. I can only assume that the impeller blades are grossed up, too. I'm assuming that it's some sort of problem with the PCV system, but I too would appreciate any sort of advice.

Some oil in the air tube is common, especially for cars this old. The turbo compressor seal is not perfect.
Joe, you may have a PCV problem also. Start by cleaning inside and out and observe how quickly oil accumulates.

Would you recommend using a solvent like carb cleaner, or is this a job best tackled with shop rags?

Brake cleaner is good and also cheap.
Since there is a lot of cleaning to do, I'd use a bucket of mineral spirits and a rag and rinse the rag as I went along.
Check the PCV system.

I am questioning if it is the pcv system because as I said there doesnt seem to be any pressure pushing the oil out. Is there another place I should be looking for a pretty bad oil leak?

i got my car into the shop today and they told me it was the turbo return line o ring. The mechanic was complaining about how he was going to do the repair. Might have to remove the cat to get to it and quoted me somewhere around 4 hrs. to complete the job. I am having a hard time justifying the 4 hrs. in labor for a 12 dollar o ring. Is there anyone on here who has done these on a S80 T6? I know it will be a pain in the butt. Do you think your average do it yourselfer could do this?

I understand it can be done by a DIYer but a real pain. Especially the driver's side one. I believe they have both been done on my 1999 but I still have a small leak and I believe it is actually coming from the little flanged joint which is the other end of the return line where is attaches to the turbo. The 'o'ring, which you are referring to, is on the end which goes into the engine block. I don't think I would tackle it unless I had an auto hoist. No room in there for large hands. Not a maintenance friendly design in my opinion. Wish they would make the design engineers do some this maintenance to see what a pain it is....
