Alright so i'm posting this up for my brother, this is the first time he's ever made a vent/catch can (For the car we are building together). This will be for the two -12 lines out of the valve cover. Here are a few pictures of the catch can. The first couple is just it tacked up with the top being cadboard for fitment. and the rest are it welded without the top welded yet...

I'm trying to figure out what we should do for baffling. This WILL NOT recirculate to the oil pan and will be emptied. I got a couple ideas how I want to do it, but wanted to see if anyone had any recommendations that will work well. Thanks

 

nice!! very nice...

cant tell you anything about baffling though

 

haha thanks for the compliment man

 

I just welded in some aluminum plates that divert the gasses down as soon as they get in the can, then into a cube that has steel wool. Helps separate the oil and then let the fumes vent out the top.

is it just me or does that alu. look crazy thick?

 

i run an open vent catch can, that drains, with no internal baffling and ive never had any oil problems on the dyno or street...


since you are going manual drain, add some baffling over the air exits and maybe one laterally to stop it sloshing

i would put the filters higher as well if you can as well


curious why you dont want to recirulate?

 

pretty nice. that aluminum is pretty thick. lol

 

Yea the aluminum is a little thicker than usually used, for some reason it's looks REALLY thick in the pictures but it's not bad at all in person.

And for the guy wondering about recirculation I didn't want to drain to the pan with steel wool in it and also only have two return slots on the moroso pan. One is for Turbo return, other is going to be oil temp. I would drain back if it was something that would see the street a lot more often, but it will mainly stay at the track, and we have a quick & easy solution to drain it.

 

Stainless steel wool.

 

looks good tho.

maybe add more filters, why not you have space

old racers rule is have twice as much area for the vent as you have tube running to the catch can

Be careful with any sort of steel wool. If a small piece breaks off, you can risk having it sucked into your engine depending on how you plumb up your lines.

You can use chain link

 

I actually used stainless steel windoe screen... Same stuff I used for most turbo "filter"...lol Works well, fine enough to cling oil and won't break into pieces like steel wool.

 

looks good

 

Steel wool will do the job, I agree with your notion of not running steel wool in a can that is plumbed back into the oil pan.

 

the concept behind the baffling, other than deflection, is to add internal surface area thus allowing the oil vapor condense more readily. when i fab catch cans i usually use laps of preferated 0.040 alum. ive always been afraid to use steel wool
