withstup: Just because the RB has that problem, doesn't mean the CA will. It's possible that it will, but I wouldn't look there first.
Also, as, he said, you need to look at the tube that runs from the back of the intake side valve cover, to the top of the oil filter mount. That tube is infamous for crusting up with nastiness and causing the problem you're complaining of. The reason being that if it's gunked up, the crankcase gasses don't have any way to get up to the head except through the oil drain passage, which can appear to be the same problem as the RB, but is caused by something totally different.
