i know they are needed to rid the motor of built up pressure, what other ways are there to accomplish the same feat that is cleaner looking? my new motor will need a setup and im trying to make the motor as clean as possible.
on a side note, can you do away with the breather and just run 2 pcv valves or do i have no idea what im talking about
thanks!!

The breather allows fresh air to enter the crankcase to flush out the blowby gasses. That won't happen with two PCV valves.

you have to have one vacuum source, the pvc and one return
what the engine sucks out of the crankcase must be replacedit is not to keep presure from building up in the crnakcase but rather to suck out gases and moisture in which if allowed to collect in the crankcase will contaminate oil and turn to acid due to water moisture content buildup
you need one pvc and one return
good luck
