Homemade Catch Can

The PCV is run from the passenger side valve cover to the plenum. The crankcase breather tube is run from the rear of the drivers side valve cover to the intake pipe on the drivers side turbo.

Pre-boost IMHO, or you will have problems I would think. You would end up pressurizing the engine block, I would think oil and fumes would blow out the path of least resistance, along with your boost. Mine are pre-boost.

I just completed my install. I went to Lowes and got the following since they don't seem to carry the Campbell Hausfield anymore. Thanks to i8acobra for this great DIY mod.
Kobalt filter model#221024
And Kobalt Barb/clamp combo packs model#124224

I didn't manage to find the catchers you guys have used but I did find one, which I installed today. Once I was done, I noticed I could hear a sound coming from the hose area and began looking for any creasing in the hose. Out of curiosity, I touched the little release button on the bottom and it was drawing air INto the catch. I double-checked that the arrow was pointing to the plenum and that the lines were not pinched. My catch has a release valve on the bottom that is held closed by a spring. Pressing the button on the bottom opens the valve and drains the liquid. If the valve is sucking air in, then it is being sucked open due to negative pressure in the can. At this point, I am not going to keep the can on until I can get it right.
What's going on? Why would there be negative pressure in the can and where would that pressure be coming from?

bumping an old thread. I did this over the weekend, removed the entire filter and baffle assembly, this is correct right? Any rate I notice that there is a sucking kind of noise. I've checked all the clamps and they are on tight and the arrows are pointing to the pleneum. Anyone else have a slight noise coming from the catch can?

I was asked how I sealed up the nipple at the bottom of the catch can.....
1 - removed the 'c' clip that holds the barb in the housing
2 - removed spring
3 - replaced barb and 'c' clip
4 - while pushing the barb out with a screwdriver from inside the housing, I placed a vacuum cap on the barb (cut to length)
5 - zip tied it as tight as I could get it because I had no hose claps that small.
Here's a pic of the finished product (sorry it's a camera phone pic):
EDIT: that pic sux, I'll try to get a better one soon.

So I threw one of these on last night, followed the instructions, sealed everything up, clamped the 50psi fuel hoses down, the flow is going toward the manifold. I glued the bottom valve shut, so no air gets in or out.
Started it up. There is a slight hiss on the longer lenght of tubing im guessing from the vacume narrowing the tub, but it still flows. Let it run for a bit and every min or so, there was a click in the engine bay and the idle rpms would drop to about 400. It would still run, but just kind of hicup for a second and ran rough for a moment.
After a 15 min idle the CEL came on. I did the pedal trick, turned it off. It came back on, I turned it off again, connected a big ground wire from the neg batt to the frame and went to bed.
This morning, no CEL, and the car ran fine. The catch can already caught some oil, so i wanna keep it, but i also want the car to run properly.
What do you make of that?

Mine seems to fill up all the way to the top every 3-4 weeks. Anyone else running into such a high consumption. I also have a slight hissing noise but not CEL, anyone else? Is it imperative to seal the botto nipple even if it has a cap?

Finally get to do this after getting the car back.
I picked up the filter @ lowes, it's blue so it matches haha.. it's by Kobalt.
only thing I notice it has a small barb at the bottom with a spring to push it out when its filled I guess, will this leak? should I cap it off? Heres a blurry phone pic:
I see the husky's come with a vac cap on the bottom of theirs. I think the newer ones have this valve that opens and closes it but I wouldn't trust that...
Thanks.
