Oil Catch Cans

[Damo_R34]

Hi guys,

theres alot of info flying around in other areas of the forum, so i wanted a place for people to post up pictures and specs of their oil catch can installation. Please keep this very on topic.

I will be modifying my system soon so ill post up results once complete.

Here is a useful thread to read up on. http://www.skylinesaustralia.com/forums/Ca...ans-t68174.html

Here is SydneyKid's recommended RB25 setups. http://www.skylinesaustralia.com/forums/Ca...html&st=20#

Thanks.

If anyone has any pictures of a RB26 with a oil catch can setup, that'd be awesome.

All I ever see is RB20's and RB25's with oil catch can setups with extreme diagrams and walk throughs.

And pictures:

Theres 3 that ive seen... ones the autech can that sits on top of the rb26 at the rear..

The other is one that sits in front of the battery - Blue32 had one of these

And theres another one which is an oil/air separator (nismo, non vented) that hides underneath the ABS unit...

Maybe andrew can take some pics of his current setup as from the sounds of it, its pretty bulletproof

heres a can for the 50% plumb back option:

3 in/outlets, removable top so you can pack it full of steel wool (in a stocking!)

Thats pretty much what im running at the momment Damo, seems to be doing its job

That looks like a similar design to the one that ISC sells ;

They are the cheaper versions of the greddy oil catch cans.

Hey, i got the same one as that...havent hooked it up yet but where do you connect the hose to at the bottom of the can- like where does it go to

Drifters catch can of choice.

Serious note.. I run 2 as its neater, I'm not a fan of hoses draped over the motor.

One either side of the motor feeding off that sides cam cover.

One sitting in the drivers side engine mount and the other behind the A/C compressor.

Since oiling mods the cans are always empty.

Have you got a pic.....still deciding how i want my setup to look

Yeah pretty much, there just the Greddy "style" cans. We have them on special at the moment for $50.

RB26dett catch can set up.

An engine bay pic would not be useful as it looks like a standard engine bay. You can't see hoses or catch cans.

I'm soon to rip the cams and lifters out again so I'll grab some pics of the bits underneath the manifolds.

If you can visualise...

The passenger cam breather that runs to the inlet pipe has be redirected in to the catch can that resides behind the a/c compressor / under the exh. manifold.

The hose that runs from the drivers side cam cover to the PCV/plenum has been blocked and a T piece positioned in the middle; a hose connects to the bottom T piece connection and runs under the manifold to the engine mount where the catch can is located.

Really depends on how tidy you want the engine bay to look.

Heres a thread for the autech type over the head unit

http://www.skylinesaustralia.com/forums/JJ...nt-t166910.html

It's a sealed catch can and has no breather and so is legal thru regency (they might say otherwise, but the legislation allows oil/air separators that don't have an atmospheric vent

there is another type from nismo ;

http://www.rhdjapan.com/jdm-low/NISMO-Oil-...-Kit-GT-R-55665

Which I imagine does the exact same thing as the ISC can since I can't see an atmo vent anywhere on the it (unless I'm missing something - $800+ AUD vs $50 aud? Crikey.)

I think eventually I'll get the ISC one and the Autech can as well as drilling an oil return from the head and putting in 1.5mm stoppers in the oil channels, and a sump baffle from somewhere. That should be enough for any street car.

lol Joel, you redeemed yourself with that last line

seriously Damo, unless you've done what Joel and others have done in relation to baffles and restrictors, do not try this method.....2 laps around Malalla and they'll be full.

I still believe that the 2 can setup that I described earlier is still the best for no other mods to restrict the oil

[SLAPS]

ROFL!

Definitely agree. Mine has a fair bit of oil pressure over 3500-4000rpm (~90-95psi).

Without the oiling mods the cam covers were filling on the dyno to the point where I could only just see the lobes poking through the top of the oil level, oil was blowing out and filling the catch cans in no time.

After the oiling mods there's only a slight puddle of oil after a hard extended run and no oil in the catch cans.

yeah funny how quick the oil gets up there and how slow it drains back, hence why a popular mod is to relieve the oil returns in the head slightly....suppose everything helps.

Here are a couple of options that will also help oil drain back while the head's off....welsh plug replacement at the rear of the head and fed back into the sump (just to help speed things along).

[mid life crisis]

on our speedway engines "v8" we used to tap a fitting into the back of each head and run a hose from them back into the sump cheap and easy .
