Well I know about the faulty oil vapor problem of the 1jz, and there's a couple ways to avoid it, but I'm just going straight to catch can to get it out of the way. First of all, I was wondering if there was any recommended ones (Browsing ebay but they all seem to function the same :ugh2: ), and also wondering if there's any detailed instructions on how to hook it up. I constantly see threads with people hooking up the catch cans wrong and I only want to do it once and I want to do it right.

Sorry for the 2nd thread in a day, well sorta, I mean it is 2 AM... :ugh2: :ugh2:

I have an ebay one, and it works great. I had to modify the sight glass (actually rubber, not glass), but aside from that it works great. I'll post a pic tomorrow.

Same exact one I have. I replaced that clear site glass with rubber hose as it leaked when I'd go in boost, and I replaced the white oil hose with better black rubber hose.

I have a catch can installation question with from your pic there pituala. Do you think it's better to install the can where you did, connecting to the intake manifold, or on the other side of the valve covers, connecting to the intake piping.

I ask this because under vacuum, oil can be sucked into the intake manifold, but under boost (without a pcv valve), oil can be blown into the intake piping.

Edit: Here's a pic of what I did



The bracket I mounted the can to was just sitting there, even had the same thread as the bolts that came with the can.

Well I did it the way you see in my pic because I upgraded to the 2JZ PCV valve as well, so mine doesn't have that problem, and I get absolutely no smoke at all.

before.......

after


so basicly all you do is remove that hose that goes from the intake pipe to the valve cover and replace it with the catch can and lines

ps. special thanks to paint, couldn't have done this without it :ugh2:

That's not how I have mine hooked up. I have my PCV hose going to the catch can, then the return line from the catch can going into the intake manifold where the original PCV hose went. No smoke and no problems at all.
