H@ME Posted November 14, 2007 Share Posted November 14, 2007 Okay guys i just finished putting the hoses on the can and all i think is well so far, there are pics below for feedback, i think all is well with the installation. Apart from i have one more inlet/outlet at the bottom of the can which can just be seen in one of the pics, should i just block this inlet/outlet? Also is the position ok where it is, i know it is close to the turbo heat shields etc. Think shouldn't cause a fire should it??

R338OY Posted November 14, 2007 Share Posted November 14, 2007 Nice job dude I think where it is should be fine. Is it worth doing? Cheap and easy to install? Or is it depressing?

H@ME Posted November 14, 2007 Share Posted November 14, 2007 It is a very simple mod to do, where u located, i'll do it for you if ur close by, anyhow is it cheap? depends on where u get ur CC from, what brand it is and what it is made out of. installation can be slightly tricky but i'd say it a begginers/medium mod.

R338OY Posted November 14, 2007 Share Posted November 14, 2007 Wanna fly down to Sydney and put one in? hehehe I'd be confident enough to install one. How much for one *average* price? Plus i'd go for the steel hoses (don't like the whole garden hose look on some of the installs).

I'll snap up a photo of my setup on the weekend when i get my car back, its currently getting resprayed can't wait!

Dose Pipe Sutututu Posted November 14, 2007 Share Posted November 14, 2007 if you look at: - Yellow line & T-Piece those lines are sucked into the oil catch can - Blue line & T-Piece are sucked out of the catch can. With this setup when the car is: - Idling the blue line will be sucking from the catch can, which is drawing the fumes from the cam covers. - On boost, the blue line will be closed off by the PCV, and the intake will be drawing air from the catch can which is drawing fumes from the cam covers. 100% plumb back solution..!

Dose Pipe Sutututu Posted November 14, 2007 Share Posted November 14, 2007 Iv read through the thread and im still finding it a bit confusing. Which way is the most efficient way to set up an oil catch can? Most efficient is what I posted up, so on idle & on throttle the oil vapours in the cam cover are passed through the catch can. In a 50% plumb back solution, only on throttle is the vapours passed through the catch can, and on idle the oil vapours will travel into the plenum via the PCV.

Dose Pipe Sutututu Posted November 14, 2007 Share Posted November 14, 2007 Sorry I have a RB20DET, the PCV is actually located on the Plenum, I forgot that the RB25DET have their PCVs located on the cam cover. Solution: get a generic PCV and run it just before the plenum.

R.3.2.G.T.R Posted November 19, 2007 Share Posted November 19, 2007 while we are on the topic, could someone tell me the correct way to hook it up on a RB26.. i was told its almost mandatory to have this on RB26's..

Dose Pipe Sutututu Posted November 27, 2007 Share Posted November 27, 2007 this is how I hooked mine up, but please note its a RB20, i.e. the PCV is actually on the plenum, RB25 guys should go buy an inline PCV from a local spares shop.

Neejay Posted December 28, 2008 Share Posted December 28, 2008 this is how I hooked mine up, but please note its a RB20, i.e. the PCV is actually on the plenum, RB25 guys should go buy an inline PCV from a local spares shop. Is there anything wrong with this setup? So I'd just have to buy ANY inline pcv valve? Sorry, I know it's a year old post, but this is the best way (I think) I've seen a catch can setup. I'm trying not to have to run 2 catch cans, because I want to filter out the pcv valve vapors AND the valve cover vapors.

SirRacer Posted December 28, 2008 Share Posted December 28, 2008 i ripped mine out and replaced it with a blanking plug. the hoses from the rocker covers run into a catch can. ive seen some pretty serious rb drag cars running similar setups so im sure its not 100% essential to have the pcv operational in that manner. If it is, id be keen to hear about it?

gotRICE? Posted March 14, 2009 Share Posted March 14, 2009 is my catch can set up correctly? Yup, but in that setup you can block the PCV off too. I have mine set up like yours but with the PCV blocked off. You cant see it because i painted the PCV bung black. Removed the valve and replaced it with an alloy bung. And of course a bung in the PCV-Intake Mani hose.

Adz2332 Posted June 19, 2014 Share Posted June 19, 2014 Long story short i can run the two pipes off of the rockers to a catch can and then use a fliter on top and thats it? let it vent to the atmosphere and no other lines are needed to be run? Can anyone recommend someone to custom make one and that knows how to baffle properly?
