i dont run a catch can i only use a breather filter on the stock VC vent and it is ok but id like to add another vent next to the stock one with another filter on it.. but the stock location uses baffles to stop the oil dont it? what should i do if i add another ? or am i forced to use a catch can then? sohc motor

 

take 50$ and buy a catch can...

filters are not good on just ends, they are restricting air flow and putting unnecessary backpressure on your motor.

 

ok.. how does that add pressure? the filter has very lil resistance? i had a catch can but it built up alot of condensation so i didnt like it.. anyone know the answer to the first question?
