View Full Version : will this catch can location work?

I bought a Greddy oil catch can that came in yesterday. I went outside today and mounted it up, but couldnt find a place to put it in the usual location, right near the intake filter (still using factory sidemount). So, on my car there is a bracket hanging down in front of the starter on the firewall and it is not being used for anything. So I bolted the catch can to that bracket and ran the hose next to the starter cable and around to the other side of the valve cover.

As for the other bung, I'm about to order an intake pipe from a group buy that comes with a bung for the catch can.

My question - Will this setup be okay or will I need to move the catch can closer to the intake? Also, until I get that intake pipe, I put a breather filter on the other bung on the catch can, will this suffice until then?

it doesnt matter where the catch can is located just as long as it is lower than the valve cover so gravity can do its job.

i put mine right behind the drivers side headlight....took the light off, drilled 2 holes to line up with the holes on the catch tank and put 2 bolts in...works great!!

I'll get one when I can find my digital camera, it's currently MIA, so until then hopefully your imagination will suffice.

Makes sense, just wasn't sure if using too much hose would be bad.

I thought about that too, because, like you and many others, it seems thats the most popular place to bolt down the can, but I still have the factory sidemount, so those two hoses are in the way, plus the intake filter is pretty far up in that corner behind the light. Besides, I saw the bracket with a hole in it under the starter and couldn't resist the ease of installation there.

So should it be okay with that breather filter on the other bung on the catch can itself? at least until I can get that intake pipe with the bung for the catch can on it?

there are so many places variations of where catch can could be located, some i've seen of freshalloy, had it right in front of the valve cover, i've seen one by the firewall passenger side, i've seen with/without breather, there's the horizontal looking catch can, etc etc...

ah, I see. Essentially that's how my hoses are run. One from valve cover to can, then a breather on the other bung.

but then again, i've seen so many more setups when the other hose goes back to the air intake pipe

to tell you the truth...it really dosnt matter where you put it, how long the tube is or any of that, and the tank really serves no purpose unless your racing and running it at some high RPM's, cause all its gonna do is catch the excess oil splatter out of the head, and for regular driving your not gonna get much if any. Well depending on the condition of you engine that is. So just put it where ever you things it looks the best or where it is easily installed.

not completely correct... the oil catch can is also there so that u can pull vac on the crankcase without sucking in oil... or getting is all over the turbo. thats why it has baffles.

if u arent pulling a vacuum on the case - then yes, its just to catch blowby...

the orange car above is very kickass, and he doesnt pull vac through it - prolly partially bc he has no intake pipe (last summer he rocked a 2871R with an ext gate still with no intake pipe - BALLER) he'll prolly raise the bar again with his rhd conversion he did.

so the way mine is setup atm is it still being pulled through with vacuum?

I didn't think the KA had a PCV valve... anyway, SR's do, and that's the whole reason we need catch cans. So yeah, I run heater hose from the PCV valve to the valvecover (covered with thermal foil), from the valve cover to the catch can, which is bolted to the passenger strut tower (only place I had room), and the other hose on the can is on the intake. This way the intake creates a small suction on the catch can, helping evacuate the PCV air to put a little vacuum on the crankcase, and pull any blowby from the valvecover through with it. Have yet to see any appreciable oil in the can though.

you have yours hooked up to the PCV system intake. Shouldn't have anything in it as that's where the air goes into the block. The gases come out the block below the intake manifold, thru the PCV valve and out the T bar into the runners. Only reason you would get blow by is if the PCV failed.

It would be better to install it between the PCV and the T-Bar under the manifold. You can see how nasty the runners get.

The runners don't get nasty if you weld them up and leave the PCV vented to atmosphere.

wow - the sr has a similar thing goin on with th eintake mani - mines clean inside tho :/

punxva - yours is set up properly if its in fact hooked to the intake pipe... i cant see it good.

when hooked to an intake pipe it always pulls vacuum... thats kinda the point - sr's have it stock to preturbo after the maf of course - but with no baffled catch can it gets oil on the turbo.

:ugh: did you look a what I posted with how the pcv system works? The intake is on the intake pipe cause we use a MAF and any air entering needs to be metered.
