HOW TO: DIY catch can

[gfrg88]

Sticky damnit!!!!

[import racer]

So when I do mine I think I'm just gonna run hose from valve cover to catch can and hose from pcv valve to catch can with a breather on top.

Still confused on the black box Plumbing and shit...

why?

[gfrg88]

Cause Ive never paid at5ntuon to it lol.. doesn't one line go back to oil pan?

[Tdurr]

Yea, one line goes to the oil pain, it's the drain back for the stock "catch-box" u can remove it and run a line from the block to an aftermarket catch can and plug off the return on the oil pan if u want.

Thats what I understood from looking this up when I was originally setting up my turbo stuff.

[vteckiller]

Why not just use a power steering resevore? or what ever its called... its already got a hole in the bottom. and two on the sides.. and a lid for the filter.. and its already got a built on bracket.. and.. its free.. comes with the car.. LOL? work yes or no?

So plug the return line. gotcha. that's where I was lost.

Sorry Gio. I havent felt like posting much lately. Tim got you lined out pretty good.

Bump for a possible how to.

Jerry i just redid my catch can setup using the same Designed(same one i had on my boosted a20). Only thing i did was took off the Bottom drain and added a 10AN fitting. but i cut it down alittle so oil can return to my pan. Look at my pic at my build thread. Ill have to post a pic of it redone.

[89T]

I'll take a look at it.

Bump

this has to be one of the most simple but effective can iv seen. Great job!! there will be one of these on my hatch and just may make it to the sedan.

Question.

Onn a can with 3 openings, can I run the two bottom openings to the valve cover and pcv valve.

Woth the top opening to the air intake tube for vacuum? With a filler in the can such as scotch padding to grab oil.


Seems like aan easy way to hook it up while still keeping oil out of the intake.

[89T]

Sure, that sounds like it will work. Although the pcv should see vacuum all the time. Anyone want to chime in on the pcv.

Well it was the intake or the existing pcv vac port for both. Either one should work.

[89T]

for some reason it seems like your response changed. Either way, I would take the vacuum off of the cai. There is no reason to pull a vacuum on the crank case at idle. Besides if you were to just pull vacuum off of the pcv port without a pcv in place it will act like a huge vacuum leak.

[CzEcHy]

Lol UIm going to make an ms paint view of what I mean.

Pcv valve would still be in place fyi, catch can is just a filter between pcv/crankcase and intake manifold. Everyything else stays the same
