Since GTM TT kits don't have anywhere to connect that PCV line (inlet on top of valve cover) to the intake, what have others done?

I am going to take pics now of how it is installed and post them in next 30 min.
What? We most certainly do. It's on page 66 and 75 of the instruction manual. Each bank is supposed to connect to the supplied fittings on each respective turbo inlet pipe.

Here is where the tube crosses over to driver side and towards catch can.



Here is driver side PCV inlet (fresh air).



From there the two lines are tee'd off and connect to the oil catch can (the outlet of the oil catch can).





The PCV outlets are not connected to the oil catch can and are still going from front of manifold back to the back of the manifold (vacuum).




The catch can is doing nothing. Am I wrong?
It's hard to tell from these pictures because I can't see what (if anything) is connected to the left outlet of the catch can. If one was trying to "tee" the PCV lines together, I wouldn't route the passenger side line like picture shows.

In our Supercharger Installation manual, we tee the PCV lines together and page 71 & 72 shows how we did that. Much tidier than what you've got going on there with the zip tie to the upper radiator hose.

Anyway, I would check the turbo inlet pipes to make sure the 3/8" NPT to 5/8" barb fittings are installed. If neither pipe has it, then you need to pull one or both off, drill & tap the pipe, install a fitting and route the PCV line to the pipe. Make sure that the PCV line isn't going get caught up in any moving components or rub on any sharp edges/components in the engine bay.

Here are the links to the instruction manuals I referenced in this post:
