Moroso makes it. Its a part of a kit:

You can just buy the nipple for $9:

And a check valve that threads onto it:

i got a setup like that i have made for my car. I haven't been able to test it yet but in theory it should work excellant.

I ran a -8 line from the oil fill tube to one port on the catch can than the other port went to the siphon tube i have mounted in the downpipe. I used the above checkvalve but had a -8 fitting welded to it.

I really like the overall idea and fundamentals of how it should work. Although alot of the setups i have seen like this have not ran a cach can i decided to run one just because i don't want all that burnt oil being spewed all over my rear bumper.

Awesome Joff, thanks much, took me a while to find it on moroso's website.... those are the individual part numbers.... I'll have to go and find the kit number and post it up so anyone who wants to see the destructions can look it up. Looks like a really trick piece, might have to rock that in the future.... after you giunea pig it


Good call Zack
How is your can setup? Entrance on the bottom, SS wool packed inside, vent on the top?

Actually a vent on the top would defeat the purpose and allow the system to no longer have a vacuum on it. lol. I'm using a greddy catch can with the two ports on the top, and i left it open on the inside and used one port to pull from the oil filler neck and the other port goes the the exh vent.

The theory works just like it does when it's plumbed into the intake track, it pulls vacuum on one side to help pull the pressure out of the sump. They have been running setups like these for ages on muscle and roundie/round cars. Latley in the last few years it has really caught on in the import scene(big hp supras and surprisingly VW guys). Seems to work very good from the general consensus i've gotten from talking to a few shops around florida.

Vent was the wrong term, that's what I get for posting when exhausted... happened a few times yesterday actually.... vent meaning that's the port that's plumbed into the vac source. I'm planning on setting mine up this way to try to get any oil that flows up the center iron to be pulled back into the sump. The moisture and the vapor can all be pulled away though.

The moroso "kit" is very V8 piston engine specific. IIRC, it comes with the valve cover insert and 2 slash-cut tubes and 2 check-valves -- one for each side of a V8 exhaust. Thats why I only posted the sub-part numbers.

Having just been at SEMA where I picked up lots of catalogs, I noticed Vibrant Performance also has some parts supporting this setup. Theirs has a male -10 AN fitting, threads into an angled O2 Bung (M18x1.5) and is available in either mild steel (Part no 11189) or stainless steel (Part no 1189)

The Vibrant ones are pure sex!!! I will def be ordering some of those next week.

Vibrant is distributed throught Verocious Motorsports, I've done alot of business with them and highly rec them.

Sweet!! Thanks Brian!

No worries there Zach

Here's the linky

I like the idea.... but -10? REALLY?

[rxspeed7]

Yea -10 is a bit overkill, but at that point you could either get a step down fitting or cut it off and weld a new fitting on it. Either way i like the fact it uses a o2 bung and thread to go in the exhaust. Makes it a little bit more serviceable than straight welding the tube in. Plus at $20 you'd be hard pressed to by the parts to fab one your self.

Did you end up going through with this idea?

[TitaniumTT]

It's on the todo list before DGRRXI but yes, I am going to do it. Going to use the Vibrant piece, going to buy it through Verocious, and I'm going to build my own tanks. Waiting till I get my MC installed becuase I'm going to need remote resevoirs and I want to build an MC brace, and since they're all going in the same spot, it's a plan all three at the same time kinda thing.
