Thread: 300tdi-oil in diaphragm cover on FP

I took the cover off the FP to see what adjustments had been made and found the diaphragm had oil from the turbo on it (see pic). There was no oil lower down/on the other side of the diaphragm. This cover hasnt been off for about 80000km.
I blew through the turbo line and it is unrestricted and no oil blew out - so there isnt a lot in there. Is this a concern? Will the diaphragm degrade from oil contamination - I expect performance will suffer drastically if that happens?


thanks

PS: photo needs to be rotated 90 degrees clockwise - then the front of the car is to the right.

The oil could only come from the compensator feed line from the turbo, but you already knew that.
Guess it is a sort of blow by, that has built up over the years.
I would imagine the rubber diaphragm would be oil resistant due to the environment it is dwelling in.
Check it again in a few weeks and see if it returns.


I've got diesel seeping in on the bottom side, cant wait for that repair.
