Figures, less than 2 weeks to DGRR '11, and I find this. It's on my S5 T2, brand new BNR stage 1 turbo rebuild, but with the old stock return pipe. Leak is a tiny one, and apparently due to a corrosion induced pinhole leak where the elbow joins up with the flange, on the turbo side. It's definitly coming from there, and not the gasket or anywhere else.

Questions:

1. Anyone have a good oil return pipe for an S5 T2 they want to sell?

2. What kind of oil pressure & oil flow volume do these oil return lines typically see? This pinhole leak is really tiny; the car has to be running for a long time before a bead of oil even starts to ooze out. In the event I can't fix this before the DGRR trip, I was wondering how much of a risk it would be assuming I carry a plentiful supply of Castrol and check the oil often. DGRR trip will be close to 2K miles round trip, including all the driving in/around the area.
