DIY catch can discussion

[kamineko]

found some old pics of my attempt.

basically some tubular al. all dressed up and drilled/tapped. no, i don't have a lathe.. i have hacksaw, files and some sandpaper. it took me forever.

vapour output taken from the crank breather / manifold valve junction and fed into top of can. return comes from the side of can above the filter and goes to preturbo intake. err ill draw a pic at some point

oil/muck/water release from bottom of can

thats how i've done it anyhow. works fine, when i remember to empty it!! i would probably make it longer next time

ooh nice - bought me one offa TM recently for $65

nothing internal to capture/filter vapour yet, but did come with plumbing and fittings

yet to be installed

Here's mine, got rid of the PCV valve, big hose straight off the crank case vent and the other two run to each of the head breathers, not worried about losing metered air as i'm about to ditch my AFM when I switch to possum link.

Got the catch can from Sinco customs, I think it was around the $100 mark, and its 1 litre so its track legal

So do you just wack a bolt in instead of the valve?

[Stoffa]

I would have, but couldn't find the right size at home so I just put a piece of hose on the end and clamped a bolt inside it

Hey do you have any more pics of the manufactureing??? I'm interested...

[KwS]

how effective are catch cans anyway? would it be worth me putting one on my car?

[kamineko]

i'll look for some more pics, and effective, u can decide when u see the crud they fill up with :-X not as much a problem with newer engines i suppose, less blowby etc

Mine is relatively effective. There was oil pooling before the turbo (90* intake pointing up on 1st gen legacy's), and now without cleaning it, both it and the intercooler only have the slightest film on them. I also noticed a slightly more km on each oil change (1-200 km more before tappet noise started). But that particular side effect could have been caused by anything.

My PCV is still connected, I just fed the can with the line that goes in before the turbo.
