Installing an oil catch can
 
I've decided I'm going to install a catch on my WJ. Question is, how do you install it?

I'm presuming it will basically replace the PCV valve i.e. it attaches to the oil filler tube and oil line. I'm also guessing I'd have to fab some kind of mount for it too.

Also, are there any reasons I shouldn't install one?

Thanks in advance :thumbsup:

On the SRT, it doesn't replace the PCV valve. It actually installs in place of the stock hose connected to it on the intake manifold. So you go from HOSE->PCV to HOSE-CatchCan-HOSE->PCV.

hope that helps.

Yeah, I think I follow what you're saying. Sounds straight forward enough.

Thanks :D

Can you do this for the 99 4.0l wj or is it 4.7 up...

I'm sure I read somewhere that you could do it on a 4.0, but I'll double check it first

But I did find this....

I have no idea if this works. But when I first saw it I was like :confused: a soup can?!?

Yeah I meant a product made for the 4.0l and a write-up on where to hook it up...not a ghetto soup can haha...

Sorry man, it was all I could find. Nothing wrong with a bit of hobo chique:lol:.

I've seen universal catch cans before, so I'm fairly sure you should be able to install one on pretty much any engine.

A Catch can is a must for any vehicle IMO.

I'm beginning to think the same. After doing some reading on this, I've decided it's definately the way to go.

on my 2001 5.9L durango, I installed a FRAM clear plastic fuel filter as a "catch can", the G2 model I think. Its cheap ($5?), disposable and you can see when its time to replace it and no special mounting required, just install it in the line after the PCV fitting, takes about 15 minutes for first time install, 5 minutes after that to replace the filter once a year and looks completely stock. :)

I used this setup for years without any problems.

What exactly does a catch can do?

it filters out the oil from the oil vapour coming out of the pcv valve. that way only air goes into the intake manifold. the oil would normally end up in your intake manifold and make a mess of the intake and valves.
