* I just looked at my installation manual: All 3 of your hoses are installed in their proper locations.
* You need to do the blow-suck test to ensure your PCV Valve is working correctly, and not installed backwards.
* The amount of oil your catch can collects in a few hundred miles is normal for a KB. I am assuming the KB's PCV System flows
a lot more air through it than a stock system. All that extra airflow brings a lot more oil vapor with it, and that is what your catch can is removing. It fills up so fast - that's why I made my easy drain catch can. This thread shows how much mine collects:

* When you are driving the car normally (not in boost) (95% of the time), the PCV system flows fresh air through the crankcase, collecting any blow-by gasses, and re-enters those gasses into the motor via the rear of the Mammoth intake plenum. There is zero blow-by pressure in the crankcase. Zero pressure is going out of your oil filler neck hose. Again, all the time you're not in boost.
. . . . . Only when you go into boost: When you go into boost, the PCV Valve slams shut. That blocks-off the above system. Any blow-by pressure that builds-up trickles out of the motor via the only opening available: Your oil fill neck hose. And yes, that should be a very small trickle of flow. And only for the very short time you're in boost. Not enough cumulative time to soak your air filter. The only way blow-by gasses can be sufficient enough to soak your air filter is if your PCV Valve/system is not working/blocked, or if you have serious motor issues.
* Oil Changes: When you add oil to the motor you have to add it very, very slowly. Painfully slowly. Your Oil Filler Neck mounts to the KB intake manifold. The hole in the KB intake manifold that allows that oil to pass through to the oil pan is very small. You can't see it when you look in the filler neck, but the hole that all the oil has to go through is about 3/16". It is very, very small.
. . . . . Unfortunately, the brass nipple on your oil fill neck that has the hose that goes to your big fresh air intake tube, is mounted very low on the oil fill neck.
. . . . . So, If you (or whoever does your oil changes) add oil to your motor like a normal car, the oil will back-up, go into the brass fitting, through the hose, into your intake tube, and run down to, and drip out, your air filter. This may well be the problem you are experiencing.
. . . . . I use a funnel with a very tiny hole when I add oil. The small size of the funnel hole will not allow me to add more oil than can instantly drain down that tiny 3/16" hole. So, the oil never backs-up in the filler neck, and never goes into the hose. My funnel is also long enough that it enters the bottom of the oil fill neck below the height of the brass hose fitting. All this guarantees me I never get any oil into that hose. It is ridiculous that KB made such a tiny hole for the oil to pass through, and it is really frustrating how slowly you have to add oil, but that's the reality.
. . . . . This thread shows the funnel I use, and how slowly you have to pour it in:
