 How to fit an oil catch can to a 1JZ-GTE?

Hello,
Just wondering, before I buy an oil catch can so I can install it myself, where the pipes from the engine come from to feed into the catch can and then return again? Does anyone have any detailed pictures i could use?
Thank you.

Do I need 9mm or 15mm hose connections for the Greddy oil catch can to the engine?
Does anyone have any pictures of their setup?

Yeah I would be keen to see this too.
I just bought a catch can but it doesn't say which side is in and which is out 
It looks like this
Anyone know? Is the left one "in" or is the right one "in"? 
Thanks

I'm still not sure which side the catch can should go on, as some people have it on one side, and other people have it on the other. The majority i've seen have been on the left side. I'll take a picture to show you where mine is now by next week.

Oil catch cans can be situated wherever you want in the engine bay, most people just put it whereever they have the most space and easiest runs of hose. There isn't an "in/out" hose situation generally, its just two hoses running (one from each rocker cover) into the top of the can, some of this flash fancy wancy expensive cans have an out at the bottom (or halfway up) where the residing oil can dump itself back into the sump somewhere, but yeah... I wouldn't know about that
Generally speaking (and bearing in mind all I've ever done in the past is cabletied a bottle in the corner of the bay with my hoses going into it) you mount it wherever you want, run your two hoses to it, and empty it when it gets full... if it gets full too quickly then you need to consider how toasted your rings and/or valve seats are

That's not the problem in my case. It's trying to figure out which side of the rocker cover to put it on. Currently it's on the left side, one feeding into the can from the cover,and one feeding from the can to the intake.
Now the other side (inlet manifold side) has a one way valve on it. My can also doesnt allow for 3 or 4 hoses, only two for one side. Should I have the can on the other side, or is it fine where it is, or should it be on both sides. But then how do i account for the pressure releif, is it ok to go back into the left inlet side?

I'm confused, but I'll try... you're saying your relief outlet on the turbo side rocker cover doesn't have a one way valve but the plenum side cover does?
If so, swap the turbo side one for a elbow jointed outlet, run the inlet side one into the turbo side one then out to the catch tank...
Make sense?

I guess that is possible, but would be a bit tricky as the hose sizes are different.
The turbo side doesn't have a one way valve. Only the inlet side does. I guess that would stop the engine from being pressurised. I thought both sides would be connected to each other so you only need to use one side on a catch can.
I guess you could plug up the inlet connected, run a pipe from the inlet cam to the turbo side cam, then in series to the catch tank, then the other side of the catch tank could be plumbed back into the turbo side inlet.

*back from dead*
I have been doing a bit of reading about this lately and there seems to be quite a lot of opinions about the installations.
So assume a non vented catch can is used with and inlet and an outlet like Danish's.
I read that you could t-piece the 2 pipes from the cam covers and run them into the inlet of the catch can and then t-piece the inlet manifold pipe with the pipe near the turbos and run them to the outlet of the catch can.
does this make sense?
would it work properly?

Look for a stock black rubber hose running from the driver's side cam cover to the inlet pipework - can either be the cast alloy Y junction from the air filter or the front turbo inlet depending on which 1JZ you have.
Simply plumb in a sealed oil/air separator inline with this hose - no vents, no valves, no filter etc.

that's it?
on supraforums they were talking about plumbing it into both cam covers. this is incorrect?
I like your idea! nice and easy

Both cam covers are interconnected from the Toyota factory and the pressure is even across both, so I see no benefit in making it any more complex.
The 1JZ Jap kits I looked at are hooked up this way I describe and they have been modding the engine a little longer than us...
I've been running my 1JZ this way for 4 years and have seen no reason to change.
The function of the oil/air separator is pretty simple - separate the oil from the vapour being plumbed back through the turbos, intercooler, throttle body, intake manifold and into the combustion chamber - this method achieves this very effectively and being a sealed system is road legal in NSW.

thanks a lot!
that clears up a lot of confusion for me
just one question, have you noticed your catch can filling up with much stuff? Danish has his setup the same and said that his didn't seem to catch very much. Not sure if that just means his engine is in very good condition though?

It's collected maybe 500-1000 ml in 4 years and 90,000km....
the factory cam covers are very well baffled internally to minimise oil escaping.
oh, and my intake tract is pretty damn clear of oil residue in comparison to before

thanks mate.
will be doing this shortly as I broke the rubber hose when pulling it off. Don't know if it is true or not but some people say that fitting an oil catch can rectify any possible issues between the earlier and later twin turbo 1jz's.

yeah, me too.
I thought that since this bit is broken, there is no harm in testing this "myth" is there
