The air/oil breather system is in fact an item Whizzer "ripped off" from me, but it is just one of many modifications, upgrades, and improvements they managed to take without credit or compensation. In 99% of the cases they managed to alter each item, I guess in order to "claim" my designs as their own. Sadly each time they altered my design, the results often negated the improvement. The oil vent system is a perfect example, when Debbie at Whizzer USA sent me an email telling me she was going to use my design, but not give me credit, my wife said "no problem, because they will mess it up and it will cease to work anyway", and she was right! I designed the vent system to operate in the upright position, higher than the vent hose, and a wider O.D. chamber, and taller. My design also included a PCV valve that is gravity sensitive mounted in the top of the breather, and doesn't work if not attached to the frame correctly. I noticed in your pictures [thank you for sharing the photos with everyone] the breather system appears to just "hang" from the vent hose, I suggest you attach it in an upright position for 2 reasons, first the motor at idle will have negative crankcase pressure and will in fact let some of the oil drain back into the crankcase, and secondly if they used a PVC valve it won't close because it is a gravity valve. At one time I tested a valve [from a power brake boost system] that was spring loaded, but IT DID NOT WORK, and in fact helped remove additional oil from the motor. If the system fails to work correctly and violates EPA laws, just research this site for information on how to build your own vent system. I originally addressed the pollution issue in late 2002, and hundreds of owners have made their own systems from my designs from parts purchased at the average hardware store, and usually spent less than $10.00 in the process.
Have fun,
