Lawless Posted June 13, 2013 Share Posted June 13, 2013 As above really looking into plumbing in a catch can but on a budget do I need a race spec cover or is there a more cost affective way of doing this Quote Link to post Share on other sites
Idrees Posted June 13, 2013 Share Posted June 13, 2013 No, you can use the original PCV pipe to run a catch can. Quote Link to post Share on other sites

StuDoc 72 Posted June 13, 2013 Share Posted June 13, 2013 (edited) I'm sure there will be a few. Rubber hose and catch can. Block off the vac on the inlet mani. Edited June 13, 2013 by StuDoc 72 Quote Link to post Share on other sites

Lawless Posted June 13, 2013 Author Share Posted June 13, 2013 Cheers man if anyone has any pictures ect they could show me would be good Quote Link to post Share on other sites
har-vey Posted June 13, 2013 Share Posted June 13, 2013 Breather > catch canPCV >Catch canCatch can > Inlet manifold i was told it was pvc to catch can catch can to inlet manifold breather to open filter Quote Link to post Share on other sites
StuDoc 72 Posted June 13, 2013 Share Posted June 13, 2013 Both of those ways will work. But the catch can will have 2 ports so youd be aswell using both and saves you buying a breather filter. Quote Link to post Share on other sites
Lawless Posted June 13, 2013 Author Share Posted June 13, 2013 Thanks very helpful saved me some pennies . And now I can get rid of that breather on my rocker and that god damn chirping noise it's making Would be useful too see some pics if anyone has any Sam Quote Link to post Share on other sites
StuDoc 72 Posted June 13, 2013 Share Posted June 13, 2013 Lol dont they only chirp when they are loose? Quote Link to post Share on other sites
Lawless Posted June 13, 2013 Author Share Posted June 13, 2013 Well mines tight as a nuns whispering eye tried two different filters and don't wanna over tighten it and it chirps like a motherfucker So now I no I don't need a race rocker catch cans going inThanks But still any pics at all of this setup would be massively appreciated still new to alot of this Quote Link to post Share on other sites
WallaceGlanza Posted June 13, 2013 Share Posted June 13, 2013 Breather > catch canPCV >Catch canCatch can > Inlet manifold The engine won't be breathing at all with that set up when on boost as the pcv will be closed so nowhere for the excess gases to go. Quote Link to post Share on other sites
Lawless Posted June 13, 2013 Author Share Posted June 13, 2013 The engine won't be breathing at all with that set up when on boost as the pcv will be closed so nowhere for the excess gases to go.So which setup is correct ? Quote Link to post Share on other sites
TurboTobz Posted June 13, 2013 Share Posted June 13, 2013 Long time dispute. Most people say get two pcvs gut the one on the rocker put the new on between the catch can and inlet to prevent the catch can pressurising under boost.I just have breather to catch can to keep things simple.

StuDoc 72 Posted June 13, 2013 Share Posted June 13, 2013 (edited) To be fair the neatest and simplest way is to have no catch can. Leave the PCV to work as it was intended maybe use some coloured hose to make it look nice. And put a breather filter on the rocker.

Chris Green Posted June 13, 2013 Share Posted June 13, 2013 I've had quite a few people advise on what way to set up a catch tank.PCV>Tank>Inlet - This way apparently pressurises the tank rather than doing any good.PCV>Tank>Atmosphere - Apparently this is the best as the engine can breathe.PCV>Tank>Rocker Breather - Apparently this doesn't let the engine breathe. I had mine set up the 1st was and it caused a lot of blue smoke - I don't have connected up at all now. Quote Link to post Share on other sites
TurboTobz Posted June 13, 2013 Share Posted June 13, 2013 Nice black hose on the breather facing the ground. Them filters look tatty! Quote Link to post Share on other sites

Regarding the pressurised catch can when on boost, surely a one-way valve between the catch can and inlet would solve this problem? Either way, I was lead to beleive that:PCV >>> One way valve >>>>>>>>>>>> Catch can >>> Can exhuast to inlet before the turbo with another one way valveRocker breather >>> One way Valve >>> ^^^^^ Was the best method. Surely this way you eliminate any positieve crankcase pressure. Edited June 13, 2013 by Bluebear Quote Link to post Share on other sites
Lawless Posted June 13, 2013 Author Share Posted June 13, 2013 Basically I want my engine to breath better as it keeps blowing crankcase seals and the breather filter chirping on top is doing my fecking nut in So a catch can setup doesn't improve the breathing in any way at all then ?

Like I said filter shouldnt chirp if its fitted right. Quote Link to post Share on other sites
Lawless Posted June 13, 2013 Author Share Posted June 13, 2013 Ok trouble is I've tightened it to the max any further ill be bending over the port on the top :/ Quote Link to post Share on other sites
StuDoc 72 Posted June 13, 2013 Share Posted June 13, 2013 Hmm I dont understand why it would bend. Go on Autosiliconhoses and order a 12mm one and it will fit perfect. there only £5 or sumthing either that or ebay. Quote Link to post Share on other sites

Lawless Posted June 13, 2013 Author Share Posted June 13, 2013 So the overall answer is don't use a catch can then are people running these for a reason then or is it just bling in the bay if they allow the engine to breath no more than the Pcv valve ? Quote Link to post Share on other sites
