nitrous system looks great, but you have your amw catch can hooked up wrong, it is suppsoed to go after the pcv valve and to the intake, not in the line going to the top of the TB. Just so you know.
Just noticed how the catch can was installed. That is a different approach to the PCV blowing oil issue. Generally, you see the can after the PCV tube. Has this been helping to keep the oil from being sucked into the intake manifold?
here is how i set mine up:

I think both PCV lines need a catch can on cars with
any blowby. Here's why - at WOT both makeup (TB)
and uptake (manifold) ports are at nearly zero vacuum
and only differ by the TB pressure drop. Meanwhile the
crankcase is positive pressure. So both lines will flow
oily mist out to the intake. The makeup line is even
unchecked (unlike the PCV uptake) so has more flow
potential.
When I got the truck core to port for my TB, it had a
solid snail track from the makeup port down the throat.
I put a fuel filter in this line but haven't caught anything.
I rarely get to WOT in daily driving though, and my motor
uses zero oil between changes; it's tight. Really both lines
want an oil trap, if you want to trap all of the oil.
