After about 1 month of driving with my BMS OCC, I checked it today. First thing I noticed, the "in" port had a thin layer of oil coating it... the "out" port had ZERO oil coating it... just shows that the catch can is doing a great job catching oil.

I drive my car spiritedly, but definitely don't rag it out all the time... the catch can caught about 1.2-2.0 mm of oil in the bottom of the can... enough that I could see a fluid level as I tilted the can side to side.

But the can is definitely catching the great majority of the blow-by as there was no oil coating the "out" port.

Great job BMS!!
