Waldo Posted June 17, 2005 Share Posted June 17, 2005 ok i have done the test with the greddy cans....i have a 1L Genuine greddy catch can in my r32. Its only hooked up to the exhaust rocker cover and the inlet is still connected into the plenum...My catch can is hooked up so it goes back into the inlet......Anyways after the last track day i did..(a fair bit off trashing involved) when i got home i noticed the catch can was around 1/5 full...the pipe that came from the motor to the catch can was just that golden brown oilly colour...but then the hose that went from the can back to the inlet was absolutly spotless....this just tells me a hollow can does its job perfect..you dont need baffles and steel wool! i think from the turbulence of the blow by gas going around inside the can the oil particles will stick together to form bigger particles then fall to the bottom off the can....thus how these cans work... regards luke Link to comment https://www.sau.com.au/forums/topic/40402-greddy-oil-catch-can/page/6/#findComment-1415653 Share on other sites More sharing options...
grandmasterb Posted June 18, 2005 Share Posted June 18, 2005 Just thought id share some recent experiences with everyone.Just bought a Greddy Oil Catch Tank, the new 1L one. Now before buying i was assured it was actually an oil/air separator. Now it arrived today, only for me to unwrap and realise that i just paid good money for a hollow bit of aluminium. There is no baffles etc inside so how is thing supposed to scrub oil from the crank case gases etc etc before being re-circulated back ino my inlet? I could have just made my own you beaut, home grown, oz designed orchy bottle / bong catch can for $5. So be wary the next time someone tells you that the Japanese call their oil/air separators oil catch tanks (ala surge tanks are actually inlet manifolds) Oh well at least its shiny and is better then nothing at all yeo know where your coming form, bought an oil catch tank and it has rust on the piping inlets and the welds hadn't been finished. Ended up making my own which is what i should of done in the first place :uh-huh: Link to comment https://www.sau.com.au/forums/topic/40402-greddy-oil-catch-can/page/6/#findComment-1416502 Share on other sites More sharing options...
geno8r Posted February 15, 2006 Share Posted February 15, 2006 Hey SK. I've done my own diagrams from my own understanding, if you'd like to tell me what’s right & wrong 'advantages - disadvantages' about each diagram that would be great.Owww & please automatically assume that the PCV & so forth are blocked like in your first Zero% plumb back diagram. From my can design i would think i could only use the B. or C. setup. Personally I think i'd like the A. setup but would need a can with valve at top & bottom? If anyone wishes to do diagrams too here is a pic they can use. <{POST_SNAPBACK}> So do i run both lines from both cam covers to the catch can? as my can has a breather on the top SK, My can doesn’t have a breather on top, just two nozzles, can i run both cam cover lines to the can or must i have a breather to release pressure? If so I spose I could run one line to the can & put a filter on the end of the other nozzle, but i dont really want to have an atmos setup & i also dont want oil going into my plenum & so forth, thats why i thought I could run 1 line in & the other line to the sump? <{POST_SNAPBACK}> BUMP on this questions. believe it or not I still haven't installed it yet, but I'm getting my 100K service next week hopefully, so going to get it done then. Does any one run the 'out pipe to sump' set up? Sounds most attractive to me if do-able enough.
