Help with catch can install
 

I bought a used catch can, and I don't know where to hook up the lines. Is there any diagrams available to show the placement?

Search is your freind

Do you mean catch tank? Small black charcoal filled canister. Located where your underneath your intake elbow just above your oil filter. Its held on buy the same bottom two bolts that hold on your intake elbow.

if you dont have that type of catch can you can run a line from the filler neck to the catch can then fron the catch can run it to the primary turbo elbow.

I know the search function, didn't find a diagram. Would like a diagram to show exactly where the lines go. I'm just a little unclear on where the placement of the lines go. Thanks for the link Backyardsog, helps a little, but after reading it, it seems to fill up quite fast. Is there a better solution to hooking it up so it doesn't fill up after 20min of driving?

TurboIIrotary thanks, my motor is out of the car and it's been about a year since i pulled the motor, and I'm just about done with the rebuild. I saw the nipple on the oil filler neck. I don't remember how it was originally hooked up. What connected to that nipple on the filler, where did that line go to? Do i install the line that originally goes on that filer nipple to what ever it was hooked up to originally and put a fitting on the vacuum line to tap it and run it to the catch can. I have a single turbo. So you say hook it up to the primary turbo? Where on the turbo? Anywhere from the turbo to IC ? I don't want to drill into the turbo. Maybe the IC pipe.

I'm not sure why this guy is asking how to do it when he posted all the information needed to do it:

I installed mine drivers side right next to the abs brake system. I purchased a mishimoto small can to fit it in there and made a little bracket. This way the can sits higher than the filler neck. I also have a respeed filler neck with baffle in it.

I run 1/4" NPT to 3/8" nipple fitting on the oil filler neck. I run 3/8" hose from the filler neck to the catch can up hill to the can. The other line runs from the catch can down hill to 3/8" inlet into the intake which gives suction. I used this set up with 8MM hose with the stock twins and worked fine, not much oil at all. I went to single turbo and am running the 3/8" hose.

I plugged the other hole in the oil filler neck which used to be where the PCV vale was which ran to the UIM.
