Did they give you the OEM piece to replace the RR OCC?

[soulja620]

You selling it?

You'll need the factory corrugated plastic breather tube that connects between the intake tube sensor/boss to the PCV breather box on the valve cover. If you can't find that hose, you can try to use some 5/8" heater hose with worm clamps. Now that I think of it, it might be closer to 1", so figure in some time for a run to an auto parts store while you're removing the catch can.

Think twice before you get the RR OCC. I'm serious.

Riss Racing OCC does only use 3/8" Hoses. Have that in mind before you're even planning to buy it...
And the placement right over the two glowing hot turbos is just insane.

[Robmaster]

^^ yes, but look at your pics, the solenoid rubber lines also there over the turbos...

OMG...

This engine was designed for the amount of heat that the turbos will produce when they're pushing 6-7 psi.
Not for the extreme heat that will be the result when you raise the boost to 15-20 psi.

IMO it's a big mistake to design an aftermarket OCC that will be placed right over those glowing pieces, when the fact is that most of the potential buyers of an aftermarket OCC probably will have a tune installed...

BTW, this is what will happen when you raise the boost on our poor little N54:

I used to have RR OCC, I've now replaced it with BSH(a lot better quality and parts). RR was leaking and poorly built, no leaks with my BSH.

You bring up a good point.
Mine is on the intake side but I mainly had the flow of the tubing in mind instead of the heat. flow from engine to CC is less restrictive if it's on the intake side.
But the heat idea isn't bad to keep in mind.

Also, I used to have the RR CC as well, but that thing leaked like crazy!

[creaminz]

yup BSH OCC is located in the same spot as RR OCC, ultimate problem with RR occ is...LEAK. OCC location isn't too bad if it isn't leaking IMO.

mine never leaked and actually catches oil
