dorifticon Posted August 23, 2010 Share Posted August 23, 2010 Hi all Just wondering what people have done about installing a catch-can in an r32 GTR with an rb30dett. I had an autech-style one (big tubular one) sitting above the cam covers but with the rb30 in there, there is no chance of getting the bonnet shut. I am on a low-boost run-in tune at the moment so hooked up the factory style setup but would need to sort something out before final tune. Any recommendations about what you've used/bought/made yourself, and in particular photos, greatly appreciated. Cheers Andrew Link to comment https://www.sau.com.au/forums/topic/333928-oil-catch-can-oilair-separator-for-rb30dett-in-r32-gtr/ Share on other sites More sharing options...
NYTSKY Posted August 23, 2010 Share Posted August 23, 2010 Grab yourself a set of Mines cam cover baffles. These will greatly reduce the amount of oil vapour coming out. Then you can keep the standard setup.

Its a real catch can not just a shiny empty can.

Myself and a friend of mine put a set of Mines baffles in both of our engines (both making over 400rwkw) and vitually stopped any oil vapor getting to the catch can.

Marko R1 Posted August 24, 2010 Share Posted August 24, 2010 i run a border catch can which i got from rhd japan then modified as directed by rob @ rips. the correct way to run a catch can is to have both cam covers run individual lines to the top of a catch can which should have a filter, then run 2 seperate lines from the catch can (1 at bottom & another at mid point) back to the side of the sump so that it runs back into the sump Link to comment https://www.sau.com.au/forums/topic/333928-oil-catch-can-oilair-separator-for-rb30dett-in-r32-gtr/#findComment-5413967 Share on other sites More sharing options...

BoostdR Posted August 24, 2010 Share Posted August 24, 2010 (edited) You must have a fair bit of blow by then.Myself and a friend of mine put a set of Mines baffles in both of our engines (both making over 400rwkw) and vitually stopped any oil vapor getting to the catch can. Thats what I though, leak down is less than 2% however. I think my issue was more an excess of oil in the head and-or to much Vac return. I am running the 1st breather from the high side of the drivers cam cover now instead of the low side on the passenger cam cover. Same as the Mines R34- dual catch cans (in series) Still returning to the intake. The PCV return has been blocked off. Will post up a pic later if you like. Closed loop system to keep it 'more legal' Edited August 24, 2010 by BoostdR Link to comment https://www.sau.com.au/forums/topic/333928-oil-catch-can-oilair-separator-for-rb30dett-in-r32-gtr/#findComment-5414092 Share on other sites More sharing options...

That's how I understood it too.. My head already has the vent on the back so I will be going 3 hoses to the top of the can (2 cam covers and the vent from the back of the head) then I'll do it how Markos is, vent sump to midway up the can and drain from the bottom.
