OIL LEAK! pipe near turbo or diverter valve??

[Snoopy]

I ment to say then refit cap  within a few seconds.

If the revs don't drop (sounds like its going to stall)  then recover it has a breathing pressure issue on the crankcase ventilation system. Either the PCV valve, fine oil separator or the oil separator in the sump are not working properly. (see my very early posts about how the system works)
Im guessing they just renewed both pipes i talked about earlier. The one from the small oil separator and the air intake pipe but not the fine oil separator itself as thats an expensive part.

Snoopy, I think your exactly right, the cause of the problem has not been sorted so the seal has failed again, will have a good chat with the technician on Monday,

thanks for the advice, atleast I can go armed with some good info.

Well round 2 starts at the dealers tomorrow, to see if they can solve the leak this time, and find the route of the problem instead of just changing some pipes.

[Snoopy]

good luck.

Well i told them to keep it until it was properly fixed so heard nothing back today from the dealers. I showed the technition the problem, different guy this time, was the one who changed my water pump.

I mentioned all the info off this forum so we shall see.

Snoopy , i tried the oil cap off test. The engine nearly stalled then just ran rough for a few secs before i replaced the cap.

Interesting! I had the oil leak as well and the dealer replaced the main intake pipe. When i tried the oil cap test, my car just ran normally with the cap off! I wonder what this means!

Im not sure, seems abit 50/50 as to how it runs. Well i will see what they replace this time.

read my earlier links to the Mk5 forum.

Hi Snoopy. I read your link to the mk5 forum. The setup on the mk6 GTI engine is different so i'm not sure it applies. The author also says that "if the car carrys on running normally then the PCV valve is knackered (or so the saying goes)". I've looked elsewhere on the net and can't find anything similar for the mk6 (quite a few pages on the mk5 pcv though). I do agree though, that just replacing the intake pipe might be covering up the sympton and the oil is just being burnt by the engine. When i showed the VW technician that the engine ran normally with the cap off he wasn't surprised but i know that doesn't mean much!

I had a call from my VW dealer today about my car, they were raising something with VW to investigate, sure they did this last time it was in for the same thing. So god knows what they will do this time, when the guy called me he asked if the car was chipped, never has been, although i was about to get it done until the oil leak reappeared, something he had to ask before he raised the case with VW UK he said.

So i am now driving around in a 1.2 Polo, makes you appreciate how good the GTI is, when something isn't leaking that is.
