Yours looks a little different than supergoat's from the pics - and the one I ordered looks like sg's also. Hope it has a drain.

Yah mine's different than supergoats, I tried finding it on Ebay again and it wasn't coming up (this was last week). Not sure if whoever used to sell it stopped or what.

Yes, mine has a drain, and the little tube on the side to show the oil level.

Took the accordian pipe off the REVi intake today, and confirmed there was a small pool of oil condensation gathered in the accordian.

That's all I needed to see. A Catch Can is in my immediate future.

Thanks all for bringing this issue to the forum's attention.

But I think everyone needs this mod--e bay sure has bargins.

is your mount higher than the stock intake vacumm thingy on the intake or higher than the oil one? Doesnt the catch can need to be lower than those or does it matter?

It shouldn't matter. The oil gets separated during the sudden change of the flow direction.

Hey Olddragger,

Sometimes I just like to build stuff and this looks like something I could do. Does this look like what you put together?

yea basically. I made mine with a flat top style cap on 2 inch pvc pipe and placed both my fittings on top with a hose going down to the bottom(where there is steel wool to help collect) on the fitting from the engine oil tube. I then mounted mine on the front part of my revi intake (engine side) using one of the bolts holes on the intake that was suppose to hold the bracket for the engine cover(i dont have one) painted it up black and you can hardy tell it is there. Ran my hoses in descreet manner. Has a drainage valve on bottom and it is easy to reach. Easy to do--good luck man

I knew i should have just made this myself...


I just got my rear Greddy can (the new version). First its gigantic (the can is 7" x 4" plus add almost another 2-3" to mount in on the width dimention) and at first glance will not fit anywhere in a stock engine bay. Also its just a hollow can just like the e-bay knock offs.

Not sure if i'm going to return it, sell it, or chop it up and reweld to make it smaller -shrug-

Hate to hear that -- guess I'll choose a different route.

Been thinking about just adding a small filter at the oil inlet tube & blank off the intake tube like another poster did.

The oil in the K & N filter is the after effects of the oil filler vent tube being routed from the factory to the intake manifold.

The 2nd pic shows an in-line filter, which should help. I also was thinking of using that type of filter, but just letting it vent to the atmosphere instead of back into the intake.

Cool Show you my can......

Mine -


Mounted from inside the airbox, after a little relocation of some stuff.


No drain, has some steel wool inside to function as a demister pad.

Works well, amount collected in the last year is around 5 ounces.

i should be receiving my catch can soon but, i have a question!!
would it be a good idea to add an inline filter in the line that goes out of the catch can back to the intake? that way the oil condensation can be collected in the can & the air leaving the can would be filtered before getting in the throttle body.
or... maybe i'm missing something in thinking that the air exiting the can would not be clean air...

Its up to you but it is not needed. Everything is separated in the catch can during the sudden change of the flow direction.
