Baz Posted August 21, 2005 Share Posted August 21, 2005 With so many catch cans on sale through the forums these days they seem like a pretty popular upgrade for vehicles but I am yet to be convinced as to what they actually do. What do they actually do? Is there any point in the point of modifying a motor that they become a necessity? Or are people just buying them without a real need for them? I just don't want to go spend money unnecessarily if they the need isn't there for one when I can spend money elsewhere.

Butler Posted August 21, 2005 Share Posted August 21, 2005 Im in the same boat as you man. Are they worth the $150 you have to pay? In quite a few mags they say that they are an "essential" part of drift Link to comment https://www.sau.com.au/forums/topic/84795-catch-cans/#findComment-1535734 Share on other sites More sharing options...
predator Posted August 21, 2005 Share Posted August 21, 2005 They're not essential.. maybe if your fulsik drift car is nearly shagged and about to split a ring.. but you can probably get by without one. I pulled my piping off some of my fmic piping and there is absolutely zero coating in the inside at all, whereas there used to be a little bit, so mine seems to be workng there.

williamsf1 Posted August 21, 2005 Share Posted August 21, 2005 well I find the GTR makes so much "G" loading that the oil tends to want to find its way into the intake via the turbos and intercooler... then leaning your nice A/F mixture ...... till BANG! and I dont like cleaning out all the pipes on a weekly basis! BTW I am looking at running 2 catch cans like the BSM race GT-R that SK is involved with.....

Tommyk Posted August 21, 2005 Share Posted August 21, 2005 Is that for real ? I dont run a catch can in mine, and I arent experiencing any problems Link to comment https://www.sau.com.au/forums/topic/84795-catch-cans/#findComment-1536508 Share on other sites More sharing options...
Silver-Arrowz Posted August 21, 2005 Share Posted August 21, 2005 You'd be surprised how much oil blow-by you get. My old GTR had then engine rebuild but the oil catch can would have a lot of oil/water after 5000k's. The engine wasn't all that tuned too.

SDEWY5 Posted August 21, 2005 Share Posted August 21, 2005 i cannot vouch for them enough...i guess it depends what car though also. For the Skylines you can probably get away without one but better off to have one and not risk fouling plugs and so on. I was at Eastern Creek today and not a drop of oil went into the intake, car performed solidly all day...minus that exhaust gasket...curse that gasket... Ran a Merc out at Oran park few months back and it dumped so much oil into the intake it was actually pouring out through the intake and over the front chrome grille. Also fouled up the plugs to thepoint where the car would barely accelerate at all...

williamsf1 Posted August 21, 2005 Share Posted August 21, 2005 tommyk maybe you are not driving it on the track? and by that I mean around corners.... I now have baffles in the cam covers + a catch tank setup..... however it still needs a little work, so will be adding the barrel type tank near the strut brace to catch the initial vapour.... I don't have the nice plumb back, as I'd like to keep the engine intake clean....and fueled up!

maccattack Posted August 21, 2005 Share Posted August 21, 2005 Have a read of this thread - probably most of your questions answered. http://www.skylinesaustralia.com/forums/in...topic=68174&hl= Link to comment https://www.sau.com.au/forums/topic/84795-catch-cans/#findComment-1536763 Share on other sites More sharing options...
JDMfantasy Posted August 21, 2005 Share Posted August 21, 2005 A catch can is not needed. Instead of paying $100 + for a can, run your hoses to the bottom of the engine bay, and simply have them vent to the air.

CEF11E Posted August 22, 2005 Share Posted August 22, 2005 catch cans are good for engines with 100,000 kms + and high RPM. I had one on my old RB20 and it was nessacery for drift as there was excessive blowby at 6000rpm but for normal road use you dont need one otherwise they would be a factory inclusion Link to comment https://www.sau.com.au/forums/topic/84795-catch-cans/#findComment-1536951 Share on other sites More sharing options...
Beer Baron Posted August 22, 2005 Share Posted August 22, 2005 hmm, i will have to check my intercooler piping again but last time i checked it there was zero and i mean nothing in the way of oil in my intercooler pipes. And it has seen a few track days this year. RB26 i'm talking about. Williams, are you still getting that much blow by after the rebuild?

JDMfantasy Posted August 22, 2005 Share Posted August 22, 2005 No oil comes out of the hoses. They are clear hoses, and theres nothing coming out of them, so no problems there. Also where I live there are no emissions testing or inspections or anything of that type of nature, so you can get away with non-street legal everything B) Link to comment https://www.sau.com.au/forums/topic/84795-catch-cans/#findComment-1537092 Share on other sites More sharing options...

Angry Posted August 22, 2005 Share Posted August 22, 2005 having hoses vent to air will probably cause idle issues as well ....get pulled up and the cops will do you, straight thru your pants.
