After 3 weeks if having he PCV catch can in series with PCV and instake with a lot of WOT, bouncung the rev limiter and weather in the 80s this testing has ended with no more then 1/2 teaspoon of oil in the filtered can.

Due to the catch can system reducing volume flow we find it not worth it and took it off.

Same results we saw when we first tested these "Catch Cans" 5 years ago,
