But with such a long pipe which is going down from the PCV and up again to OCC will it not condense in the pipe already?
Oil doesn't "flow" per se through the PCV. Its all blow by. Oil Catch can or not the volume of oil that makes it into the PCV is the same regardless of where the can is mounted (high / low). However, misty oil will make it through and you want the cans to collect this oil and vapor. The oil catch can is mounted higher than the PCV and thus the oils that get trapped in the lines will not make it to the cans, the vapor willl. At least not all of the oil and will either get trapped in the lines or back into the crankcase. However, this is now contaminated oil and you don't want it in the crankcase, but rather the catch can. This is obviously my speculation as the system hasn't been tested (I assume).If there is enough oil to "flow" (as a liquid) to the cans then it would seem to me that you'd have a much bigger problem!
Having the tubes higher than the PCV allow any oil that may "condense" (it's not really a vapour, so the wrong word but similar idea) on the tube wall to eventually drip its way back into the system.
The OCC's are simply there to baffle the oil droplets in the airlfow from getting back into the intake and fouling the back side of the valves, depositing them into the can for convenient elimination without altering the original ventilation design of the engine.
I did notice it looked like Rudi had removed his as well. I don't think I can fit the engine cover back on without modification but I take it off when I go to the track so I don't care if I can't use it anymore.I noticed my one hose was getting kinked up so I removed the bottom left engine cover mount. Wont be missing that as it isn't needed. There is another engine harness bracket you can remove. Total weight savings will be a tad over 2lbs.
