Only need one GM valve cover plug. The outlet tube in the other cover gets blocked with a 5/16" rubber tube end.
Don't need the overpriced GM PCV hose when using a catch can, just use 3/8" fuel line.
I have a different # for the OPSU (or OSPU, whatever) - 12562267

The crossover pipe is the coolant steam bleed... it connects the steam vents on each head (at one end of the motor) to a hose which usually goes to the radiator neck (below the overflow tube)... not related to PCV.

^ The LS1 steam vents won't clear under the FAST/LS6 intakes.
OP:
You'll need 4.5" ducting for the NW 102 TB. I've got it now and a section of 4" ducting that I've found that doesn't fit.
Also, add in an LS2 WP so you won't have to grind the **** outta the stocker and play guessing games taking the intake on and off about a half dozen times. (Same w the TB) LS2 WP has the clearance we need.
ThunderRacing has the LS6 valley cover complete with a gasket, PCV Tube and grommets for the knocks also. It comes with bolts, but those bolts obviously won't work for the 102. The 102 comes with the low-pro valley bolts.

^ What engine are you putting this on? I did the Thunder LS6 VC and it works fine with me. No oil numbers yet because the car still isn't running. I did have to clearance the block, but that was understood going into this.

LQ9 block. I'm sure you know this already, but there is an older and newer style LS6 valley cover. I heard Thunder sells the older style (the one with no holes on the bottom of the cover). I can dig up the thread if you need it.

Subscribed. I was under the impression that you could keep the stock LS1 coolant lines that run under the intake. I'm planning an LS6 valley cover and LS6 intake swap on my 2000 Trans Am. Does the above part list apply?
Any pictures of the pcv parts that I can delete permanantly after this swap?
Very helpful thread btw. Thanks
