Default LS3 Crankcase vacuum setup


This is my setup. Any problems with going in the front of the engine (behind throttle body)?

APS says to use that block off plug(behind intake), but I broke the plastic wings off it and cant pull it. My buddy's procharger setup has him using a T on the brake booster line. I just went to the front. No catch can as of yet. Any issues you guys see? Thanks...

Firstly, the drawing is terrible...and if it really is as I am seeing it, the entire setup is a problem.

I'll start with one aspect....why is your BOV connected to the valley breather ?

I guess it's too much. But the bov goes to the T which goes to intake not valley

certainly that is not what the drawing shows, so hard to know if anything else is correct ?

Finger is holding the bov line. The line on oil cap is pcv valve line from valley. Bottom of Tee fitting goes to intake.
