    Question on R&D CC Breather Kit Install


    I have searched trying to find the answer to a quick question and haven't been able to hook up with R&D for an answer. I am installing the R&D breather box and was wondering if the 2 new supplied gaskets for the box require any type of sealant. I cleaned the gasket off the two halves and the instructions don't mention anything other than the gaskets. I assume a leak would be bad.

    Also, which hose do I need to check for excess silicone?

    You need to check for silicone in the fitting that bolts to the block. It's the fitting that the grommet on the bottom of the box slides over.

    you will need sealent on the bottom of the crankcase breather were it meets the breather box, just make sure you dont clog it up. 1211 works perfect just let it dry overnight.

    Thanks everyone for the help. I looked at that fitting and it was clean inside although I did see where there is a small piece of metal left from the machining of the CC like others have found. Getting excited to hit the water soon!

    Another question - the R&D catch can has a port that comes with a filter already attached to it. What is the purpose of this port? I thought this was a closed system that sucks vapor out of the crankcase through the negative pressure created through the intake. Won't this port mess things up? Will oil vapors come out into the engine compartment? Just curious - finished my install yesterday along with the intercooler mod.

    Thanks, Randy

    I removed that filter and ran a hose to my HD custom air intake, I didnt like the idea of any gas fumes or oil spray in the hull .........dont know if it would have, just making sure it didnt.........
