Thanks for these measurements. I ordered a new set of crankcase ventilation hoses because BMW will cover them under extended warranty.

In your setup, did you have just one catch can? The N63 (not TU) that I have has independent CCV lines, each coming out of the crankcases and going into the intakes for the turbos. I'm not sure if I would need 2 catch cans or if I can join them somehow and then send them back to the individual intakes (or maybe just send to one intake.
