I know that here is where you connect the hose that goes to the catch can...But I dont have one..so what should I put here instead?

I have seen some engines with a filter installed here, but If I dont put anything can I run Into Problems??

 

just put a filter...

 

connects the intake pipe. Crankcase doesn't really collect much oil...

 

Put a filter or send it back to your intake...Doesn't really collect Oil...but since manufacturer sent it like that...than you might as well send it back to the intake.

 

how can I send it back to the intake??This Was removed I think when my Headers got installed..Maybe I should just put a filter..

 

Looks from your list you have a HKS...i have the same intake...there should be a little nipple right underneath the BOV...that's where it goes...i'll post a pic to show you.

 

Aww I already Removed the HKS intake..Now I have a custom Intake since im MAFless....thanks for your help !any other inputs?

 

What do you mean it was removed? The nipple of the valve cover was removed?

Despite what people say, the breather side DOES infact collect oil. If you were to look inside a stock Evo's IC pipes, you'd see the oily film coating the IC pipes and the gunk in the intake before the turbo as well. Nothing against the people who said the breather doesn't collect oil, but most of the people who say this are the people that run hollow, non-baffled catch cans. Yes, the breather side doesn't spit out a LOT of oil as the PCV does, but overtime, the oil will collect in the intercooler and pipes.

You can just put a filter there, but there are two sideaffects. One, if you have a heavey foot and like to boost alot, you will see more than normal oil on this side, and if you don't keep an eye on this filter and don't change it in time, it can create an oily mess. That and, I'm not sure if this is a HUGE deal, but under part throttle and in vaccum, this creates a vaccum leak introducing non-MAFed air into the intake manifold via PCV valve.

A few things a nobody like me would suggest are two of the best baffled catch cans I've seen. A Sakiou Michi (sp?) catch can, Elite Engineering catch can (both recirculated into the intake) and if you're REAL cheap, as I am, you can run the stock vaccum line like OEM, but place an inline fuel filter in the line. Kind of ghetto and ugly (you can hide it), but it does work. I have to change it about every other oil change as it DOES collect oil and keeps the intake gunk free And they're only $2! I defiantly would recommend a real catch can on the PCV side though. For that I used the Elite Engineering catch can.

Edit: I just read you're MAFless, so running a breather filter shouldn't do you any harm at all. Just keep an eye on it to make sure it doesn't get too oily. It especially helps if you tap the valve cover to accept a larger fitting, that way you can have even better "breathing" than the stock bretaher nipple that's about 1/4" I.D.
