No Crust Racing Posted November 4, 2015 Share Posted November 4, 2015 My newly acquired car has a vented catch can that is unfiltered and leaks oil from the breather unsurprisingly. At the moment both rockers are plumbed together then into the can, the can has only a single outlet which is going to atmo at the moment. I haven't checked PCV as yet but given what I can see in this pic, I assume blocked. I was going to re-attach the atmo connection back to the turbo intake after confirming/fixing the catch can baffling. That got me reading. - Do cam baffles work? The Hi Octane one's look cheap if they help. Used on conjunction with the previously mentioned can plumbed back to intake and baffled. - Hi octane list a separator and a catch can - with a sump drain which I won't be doing. Are both needed on a street car if you have the cam baffles? - Is something like a GZ Vacuum pump going to better than all of this anyway? - Plan is for your basic -9 setup so not huge power and only on the street as I have a track car so does any of this really matter besides making it legal again (plumbing to intake).

Hadouken Posted November 4, 2015 Share Posted November 4, 2015 Read this if you haven't already. http://www.sau.com.au/forums/topic/345545-oil-catch-canpcv-setups/ Get this catch can http://justjap.com/jjr-autech-type-oil-catch-tank-nissan-rb26dett.html Cam baffles are debatable. If you want to do some more reading look up fatz version 70 gazillion for his catch can setup.

No Crust Racing Posted November 4, 2015 Author Share Posted November 4, 2015 Just Jap in addition to catch can or that and nothing else?

Hadouken Posted November 4, 2015 Share Posted November 4, 2015 Run both if you want. Probably overkill just for a street car. Link to comment https://www.sau.com.au/forums/topic/460780-rb26-catch-cans-baffle-plates-and-vacuum-pumps/#findComment-7631461 Share on other sites More sharing options...
No Crust Racing Posted November 4, 2015 Author Share Posted November 4, 2015 Are those cans baffled? I assume they separate the oil from the air and allow the oil to drain back into the cam covers?

Hadouken Posted November 4, 2015 Share Posted November 4, 2015 Correct and yes it has a tube with holes in it to disrupt flow. Link to comment https://www.sau.com.au/forums/topic/460780-rb26-catch-cans-baffle-plates-and-vacuum-pumps/#findComment-7631464 Share on other sites More sharing options...
No Crust Racing Posted November 4, 2015 Author Share Posted November 4, 2015 Wish it came in black, nothing paint can't fix. Would allow me to ditch current catch can setup and use that space for oil filter relocation. Anything concrete on cam baffles?

KiwiRS4T Posted November 4, 2015 Share Posted November 4, 2015 Anything concrete on cam baffles? From a guy who installed them (not me) they have a small positive effect - not enough to fix major problems. If you don't spend a lot of time at WOT I would just run the catch can outlet to the turbo inlet but if you get an unacceptable of amount of oil in the line add an air/oil seperator in that line.

No Crust Racing Posted November 4, 2015 Author Share Posted November 4, 2015 I'm liking the idea of the just Jap one as it's zero maintenance.

Anything concrete on cam baffles? get it powdercoated .. best thing i did was get all my stuff powdercoated, not very expensive, looks good and 3 x as tough as paint Edited November 4, 2015 by bcozican Link to comment https://www.sau.com.au/forums/topic/460780-rb26-catch-cans-baffle-plates-and-vacuum-pumps/#findComment-7632174 Share on other sites More sharing options...
No Crust Racing Posted November 4, 2015 Author Share Posted November 4, 2015 Not very expensive vs a can of primer and a can of satin black from bunnings?I wouldn't mind having the twin turbo pipe done also. Want the bay to be mostly black/stealth.Wonder what the arc box would look like black.

No, not really. They don't add much. 2. If you don't have a sump drain you have to drain the catch can itself which is annoying. The separator doesn't need draining which makes it easier. 3. Probably but the merits of all this stuff are debatable. 4. The problem comes about with long periods at full throttle and full revs with cornering forces thrown into the mix. Not something you should be doing on the road. A small amount of blow by will carry a small amount of oil out of the breather of the catch can. Which makes a large amount of mess. The alternative is to scavenge it through the turbo suction (This is what Nissan does) which puts it back through the inlet system. You get oil in your inlet this way but it needs to quite a bit to be a problem. At the end of the day if you are happy with the Hi Octane separator I would run that. If it helps I have one at home I no longer want.
