They really are gorgeous, however the only thing I'm wondering about is adding a check line or a PCV valve on the intake port inlet side, I've been reading and it looks like you might need a one-way check valve so that the intake side doesn't get too overloaded with vaccuum. I have no confirmations on that.

But altogether it seems simple, take the hose off the "S" hose from the CCV and attach 3/4" hose to it and run the intake side to one inlet, and then take off the hose and keep the fitting for the VCG and run that hose to the other inlet. Cap the dipstick tube, mount it and call it a day.

If someone could confirm whether we need any check valves if doing this it would probably be very helpful to me, I'd much rather have a serviceable can than a CCV that gets clogged up.

I guess I have two questions with this:

1) Are there any negative repurcussions to venting the intake to the catch can with no check valve in line? (I.E. take both connections at the distribution piece and run them to the one inlet on the catch can)

2) It seems too easy to just run the valve cover to one inlet, and the intake side to the other inlet and let it collect and periodically drain, if it was this easy don't you think it would be a well documented alternative to the CCV and someone like German Auto Solutions would have already came out with one for our cars?

maybe using a catch = more pollution compared to the the oem ccv system. thats all I can think the difference would be.

That would only be more pollution if it was a VTA (vent to atmosphere), but with the ones i've been showing they are closed recirculating systems

I like these catch cans ,what do you think? High Performance Universal Racing Engine OIL Catch Tank CAN Filter | eBay

I like the 42 draft designs ones I linked earlier. They make an economy version for about 130. I would only buy wrinkle black so it doesn't stick out like a sore thumb in the engine bay

I would definately get black no matter what.

what do you guys think about this oil catch can?
