1.9 TDI PD130 small oil leak below intercooler

[michaelab]

My 1.9TDI PD 130 has a small oil leak which drips below the front right corner of the car, where the intercooler is. It's a pretty small leak. Any ideas about the cause?

Is this the turbo leaking oil?

The crankcase fumes are drawn into the intake for the turbo and then blown through the intake system so it's this that you usually see when a leak occurs. Could be the seals on the joint, they are rubber like O rings that harden with age and don't seal as effectively.As the boost level rises and falls in the system the hoses move a small amount in and out and this also causes wear on the O rings.
Could be the start of a split in a hose as well but you would probably notice that.
Check the part number but I believe this is what is used on the 8L 1.9 TDI. Best to change both sides on the intercooler whilst you are there.

Just checked, on the 1.9 TDI 130 the seals are these ones (57.85mm) not the ones linked above.

Have to have the bumper off anyway to fix the headlight adjusters so I will check these.
