That can looks like it should work pretty well actually. I have this one Elite Engineering Catch Can. Recommended in Wstar's write up. It catches about a tablespoon of sludgy oil every 1500 miles. It has some stainless steel media stuffed inside the cap to condense the oil out.

I thought a catch can on a N/A Z was a silly idea.. then one day I took the stock manifold off and saw oil literally pour out of it!

Seriously! Not sure you understand the principle. Oil weighs more than air. So gravity allows the oil to fall to the bottom portion of the can while the intake side pulls back in threw the upper chambers. Yes, it's that simple.

Even if you had a simple catch can with the in/ out hoses a inch apart/ across from each other the oil would still fall to the bottom. Simple physics.

I think having some direction arrows on the picture depicting which are the IN/OUT hoses might help aleviate this misconception.


I'm assuming when routing the hoses you place the OUT hose higher than the IN hose, so Air freely flows, but as you say Gravity keeps the Oil in the bottom?

There's a pic somewhere on there site. The bottom hoses are the in hoses and and the out hose are on top. But reguardless with the in/ out hoses where directly across from each other it would still work properly. I used to run a small air compressor filter ( filter was gutted) type on my 350 and it worked flawless. If you know what I'm talking about.

I'd be curious to see where they plan on mounting this in the engine bay... It's crammed enough as it is, foregoing the use of tubing for your TT kit. That's also gonna be an interesting Hose routing job.

I'm going to do mine in front center of the motor. I've moved the rad overflow and also have bought a smaller version.

Looking forward to pics. :tup:

Where did you move the Rad overflow to? I wanna get this plastic obstruction out myself. It's nothing but an eyesore... :shakes head:

Save some Money. Look at this one

Mishimoto Baffled Oil Catch Can, by Mishimoto

Looks pretty too... I dig the Red/Black.

Anyone know of a can that might not be as "cool" but have a better price? I know wstar recommends a corvette one but my concern is with the bracket that comes with it, it'd be hard to mount in our cars (he did a battery relo and put the catch can in the battery box).

Ebay prolly sells the cans/hoses cheap. And you can fab up your own bracket from materials purchased at Home Depot/Lowes.

Thanks!

I think I do since I make my own. Only baffle system that has every worked for me (SS media, two catch cans where one feeds into the other before the manifold, higher exit vs much lower inlets, etc) is a proper baffle system!!!

My exit hoses are so bone dry its scary. I don't think you understand its oil vapor, not oil. And the vacuum the motor produces under WOT is enough to suck the nips off a chic's chest. A normal can will have the vapor oil exit with the air. I've seen it a million times trying to get it to stop.

This works! Thanks Crawford for the idea! :tup:

You make great points. But oil vapors are still oil and its clear from the build up that is drained out when you clean it. Plus there is flat out oil from blow-by.

I don't disagree at all. I'm just saying if you want 100% clear air something betters needed. If you're ok with 70-80-90% filtration go with it. I think I saw you say you had something before like off a air hose? Well my air hose after still has residue in it. So it does work...just not 100%.
