Especially interested in seeing how/where you have it plumbed on the engine.

I don't have any pics, but I orig used the LS6 valley cover PCV system.
I have a 4150 intake, 90 deg adapter to a 90mm TB-I plumbed the PCV hose into the 90 deg adapter. During last winter I rebuilt the engine, found oil in the lines to the surge valve, and wastegate-the engine was sucking oil thru the PCV system-I added a small oil/water sep. and ck valve to the system, and was getting oil in the oil/water sep-i plumbed the PCV system back into the valve cover (it thru the computer off at idle due to diff vac.) now I am not getting oil in the sep.-the ck valve stops boost blowing back in the engine. I looked at the MM system, just not in the budget now.

I just run a single -12AN hose off the passenger side valve cover to a can. Seems to work.

Two right side valve covers with billet -10 to filler cap adpaters. Works great! 10an from each cover to a Moroso can filled with coarse steel wool.

Is this all you're running? What did you do with the ports on the tb?

They're all capped. No PCV, no leaks, no problems.

Isn't the point of a catch can to have a draw from vacuum to help evacuate the crank case? Or does positive pressure in the intake under boost create problems? Check valve?

if you drive your car on the street the only one to get is the mighty mouse setup imo. the open breather cans had nasty fumes at least on my car that was not fun.

I've got a cowl induction hood on my Nova, so maybe that's why I have no fume issues.

2 -12's off the valve covers here, simple and nothing fancy. I tried to keep my breather up towards the front to help dissipate any vapors/smells

i made my own.















I have use manifold vacuum to draw vapors through it from the driver's valve cover. there is a filter/breather on the pass valve cover. it has a pcv/check valve so it closes under boost. any blowby during boost either vents from the breather during boost or gets sucked though the separator when i let off the thottle.
