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.

I'm using two catch cans....one on each side. Though you can probably use one oil catch can that has two inlet ports. On the S63, the driverside will probably vent the most gasses. The vent hoses on both intake manifold banks pull gasses from the driverside crankcase.
