I just threw a hose off the valve cover and let it vent towards the ground and a hose off of the black box on the back of the block towards the ground and let it vent to

No PRESSURE!

I made mine as simple as possible. This is how I did it. I made my own catch-can using a 3 inch pipe. Disregard the filter on top. I plugged that hole already. I cant stand those "sightglass" method so I use a dipstick from the Junkyard. From idle, I can feel vacuum already. I will actually use the top to hook up a vacuum gauge once I find a cheap boost/vac gauge.

not bad, but you need a pcv valve from the intake to the can to keep boost from entering the can once the turbo starts spooling. I'm no expert, but it looks like you just need to move your pcv valve to that location instead of near the exhaust...

Are you talking to me? The can should never gets pressurized. Nowhere in my set-up that I tapped into the Intake Manifold... unless you are talking about the valve cover... that better not be pressurized....lol. That PCV valve is made of steel tho. I basically copied the Moroso Evacuation kit with parts I have laying around in the garage.

if you run a line from the pcv on the valve cover to a catch can, you can run the next line to a slash in exhaust or slash in pre turbo piping, and there won't EVER be positive pressure, there will always be vacuum. of course, there will be more vacuum in the exhaust than the intake htough. you shouldn't need any check valves that way either, since the flow is always going the same direction: away from the valve cover.

Read all this, looked up a few other setups...Now I just want to ask if this will work..
I have an ODB2 motor, so the valve cover has the pcv valve, not the back of the block...

I take a tube from the normal breather hole on the back of the head, and the normal pcv location, connect them (no pcv yet) then run them through a catch can, then split off into two tubes..one with a pcv going to the IM, one just pointing to the ground. Good?

OR

Stock PCV routing (VC to IM) and add a VC to ground with backwards pcv?

TY, its just a little wierd for me becuase the pcv is on the VC.
