TasGTR Posted June 10, 2003 Share Posted June 10, 2003 Originally posted by DennisRB30 If you get rid of the PCV system your engine will build up harmfull acidic gases which contaminate the oil reducing engine life. I just got rid of my PCV and vented it straight to the Atmosphere. Is this bad? or is it only bad when you block it of completely. I'm finding alot of oil and shite in the intake. Never really known about the PCV, lol. Link to comment https://www.sau.com.au/forums/topic/16733-catch-cans-whats-the-deal/page/4/#findComment-371725 Share on other sites More sharing options...
turbomad Posted June 10, 2003 Share Posted June 10, 2003 You can remove the PCV valve(illegal) or block it so it looks operational, but you must have a catch can to filter out the blowby gas/oil otherwise it will get sucked up into the intake/turbo/intercooler/engine. INASNT have you blocked off the PCV valve or not?

JimX Posted June 10, 2003 Share Posted June 10, 2003 Lwlux, what's VPW? And does that can come with all hoses, brackets, attachments etc or did you have to go and get that all separately?

Ryno Posted June 10, 2003 Share Posted June 10, 2003 Is there any benefit with installing an air/oil separator on a non-turbo car? Link to comment https://www.sau.com.au/forums/topic/16733-catch-cans-whats-the-deal/page/4/#findComment-372716 Share on other sites More sharing options...
JimX Posted June 10, 2003 Share Posted June 10, 2003 Oil in your intake has nothing to do with your turbo, so yes. Link to comment https://www.sau.com.au/forums/topic/16733-catch-cans-whats-the-deal/page/4/#findComment-372725 Share on other sites More sharing options...
lowlux Posted June 10, 2003 Share Posted June 10, 2003 VPW mailorder, there in epping but deliver to your door and yes they come with brackets but there kinda crappy so im making better ones also i had to go buy some hose and some fittings but that cost me like $20, and the catch can was $90 soooo its all good alot cheap than the cusco ones Link to comment https://www.sau.com.au/forums/topic/16733-catch-cans-whats-the-deal/page/4/#findComment-372835 Share on other sites More sharing options...
nissaner Posted June 10, 2003 Share Posted June 10, 2003 i've installed my cusco oil catch can good 9-10months ago, but i am yet to fill 1/2 of the can with oil ... is this normal? everything is connected correct got it checked by my mechanic when i was servicing my car last saturday... i've heard some stories like someone losing more than 1litre of engine oil on the track and stuff... i've been to 3 track days with the catch can installed and i didn't lose that rediculous amount of oil... is anything wrong here?

Steve Posted June 10, 2003 Share Posted June 10, 2003 Purely thoeretical: Catch cans take out the oil from blow by, so if your rings are a bit tired, blow by will increase, pushing more oil into the catch can. Perhaps you just have a really fresh engine?

aybee Posted June 10, 2003 Share Posted June 10, 2003 if you have a big turbo, bov, pod, cooler, etc. do you think it is better to try and bluff them and ask for a warrant? cause your gonna get fncked on either way? what do you think?

Steve Posted June 10, 2003 Share Posted June 10, 2003 nissaner, theoretical part 2: Your catch can is stuffed and doesnt work:) j/k If you take off the oil fill cap when at idle, you will soon know if you are getting much blow by - on cars with poor (compression) rings, you will notice air escaping at a fair rate - thats if the pcv valve isnt blocked:p Link to comment https://www.sau.com.au/forums/topic/16733-catch-cans-whats-the-deal/page/4/#findComment-373155 Share on other sites More sharing options...

T0nyGTSt Posted June 11, 2003 Share Posted June 11, 2003 The cusco comes with clear 'steel wired' hose. Mine went a bit brownish so it is obviously working. T.

armbrusb Posted June 12, 2003 Share Posted June 12, 2003 About catch cans. I bought an AVO unit 'bout a year ago. It has two inlets on the top and one outlet on the side. I use it on my RB20. I have blocked off one of the inlets, connecting the catch-can only to the exhaust-side cover. The exhaust-side cover is connected to the intake-side cover as normal, which is the connected the inlet plenum as normal. The catch-can outlet is connected to the pipe between the AFM and turbo as normal. I still find that I have heaps of oil in my intake pipes. I also noticed that there is never a real build up of oil in the catch can (should there be?). Am I expecting to much (thinking this should leave no oil in my intake)? Should I connect it up differently? I'm asking coz I feel like I've wasted my money - but you guys rekon catch-cans are ok.

T0nyGTSt Posted June 12, 2003 Share Posted June 12, 2003 But get this... the Cusco has a clear tube that shows oil capacity. Mine is speckled with oil. So I think there might be some oil in there...

Belly_up Posted June 12, 2003 Share Posted June 12, 2003 if you've still got the breathers connected to the plenum, then the catch can probably won't do much. You've given the air two paths to take, and going straight into the plenum is much easier than going through the filter in the catch can. So there probably isn't much air going into the catch can, thus the lack of oil. I think if you block off the line going into the plenum things may improve. Also make sure that the catch can actually contains some filtering material. Some of them rely on the assumption that you'll have one of thos cute little k&n's attached to the outlet to do all the filtering. If this is the case with yours, then without the little filter all you are doing is running the blow-by through a can, which won't do much at all.

armbrusb Posted June 12, 2003 Share Posted June 12, 2003 Thanks Belly_up, Once again for the people in the cheap seats - you reckon I should block off the line between the plenum and the intake-side rocker cover (I'd remove the valve and replace it with a brass plug). I should then run one line from each of the rocker covers to the two inlets on the top of the catch can. I should then assess whether the can has filter material in it, if it does, I can plumb back to the inlet piping, if it doesn't I should put a filter in it. Does that sound like what you mean?

Belly_up Posted June 12, 2003 Share Posted June 12, 2003 Yep thats what i'm sayin That avo ad doesn't seem to mention what, if any, filtering material they have inside the catch can. I'd be inclined to give them a call if i were you and ask them. But other than that, it sounds good.
