4Pot Posted June 10, 2009 Share Posted June 10, 2009 Ok, my car (R33 GT-R) sees quite a bit of track time, and I've noted that the majority of RB26's run an oil catch tank. It is a hideously ugly solution IMHO. Now the options I face are : - Do nothing. - Install cam cover baffles. - Install the hideous oil catch tank thing. Just like to get an idea of your experience with the above three options and any others that I don't even know about Cheers Jack Link to comment https://www.sau.com.au/forums/topic/274191-dealing-with-blowby/ Share on other sites More sharing options...
joeyjoejoejuniorshabadoo Posted June 10, 2009 Share Posted June 10, 2009 why is it ugly? you can easily make it look good Link to comment https://www.sau.com.au/forums/topic/274191-dealing-with-blowby/#findComment-4648884 Share on other sites More sharing options...
Benzino33 Posted June 10, 2009 Share Posted June 10, 2009 Frrk what it looks like, if it benefits your car and you need it, get it. you can paint it, hide it or get some cool braided lines/tubing to make it look better. I used to have blowby wrecking my life, got it all cleaned out by a mech, he said i should get a catch can to fix my probl;em ( my car kept stalling). I decided to do nothing, but coz i dnt take my car to the track or run boost, dnt think i really need one. car runs fine without one. I'd say get one if it sees the track a lot Link to comment https://www.sau.com.au/forums/topic/274191-dealing-with-blowby/#findComment-4648898 Share on other sites More sharing options...
NickR33 Posted June 10, 2009 Share Posted June 10, 2009 you should see the Racepace catch tank in my car, work of art! better yet have a look at the ones RIPS in NZ do... drool seriously though you need to run one... I destroyed a brand new HKS turbo in the old GTSt because I wasn't running a catch tank... some blowby got injected back into the intake pipe (that's where the stock breather is plumbed back into) and took out a few compressor blades if your going to go to all the trouble of cam cover baffles then why not just hook up a catch tank? cheap insurance... but then again I reckon just do nothing and hope all will be okay... afterall 26's are bulletproof at the track and cheap to rebuild..................................

bozodos Posted June 11, 2009 Share Posted June 11, 2009 Just outta interest, I have a catch can hooked up to my engine and it vents to atmo, I'm not pressurising any part of the system by not having it recirculate am i?

GTRsean Posted June 11, 2009 Share Posted June 11, 2009 Nope, to atmosphere is ok... I actually run a/m cam baffles, oil/air separator and a catch can, and it's plumbed into intake. It really does stop blowby a fair bit. High revs + high boost = lotsa blowby ish..... lol.

Chrisrotary Posted June 18, 2009 Share Posted June 18, 2009 Yeah so a lot race organizations want you to install one and vent to atmosphere coz if your motor poos itself chances are oil will being pumped almost directly into your intake through your engine and then out of the exhaust creating massive smoke clouds and an oil soaked race track a hazard for everyone. Venting to atmosphere will be less road legal (EPA issues) and could make normal daily driving less desirable due to oily burning toxic fumes getting into the cabin hence atmosphere and more pollution (EPA). But maybe a race track requirement to vent to atmosphere. The purpose of venting the motor in the first place is to alleviate crack case pressure caused by blow by. every engine has blow by. back in the early days of motoring every engine was vented to atmosphere usually without a catch can. then roads were getting slippery the environment was being thought about etc etc. without venting the oil seals will leak. and you'll have oil leaks from ass hole to breakfast time. Technically a hose from vent hole to a coke bottle is a catch can and suffice if the motor is rooted and blowing heaps of smoke. been there done that lol.

bozodos Posted June 18, 2009 Share Posted June 18, 2009 I had a "performance mechanic" try and tell me the other week that I was pressurising the system due to having an atmo catch can and that it was the reason my intake plenum bolts were loose and had a greasy buildup around the gasket :S but yeah had already heard otherwise that venting the system to atmo was fine apart from the legalities of it.
