pcv setup and breather
how should i be routing my pcv and breather? after i put in the new pcv and routed it to my intake manifold i thought for a second, if it sucks air out of the valve cover the idle will go crazy with a breather on the opposite side. so i should accually route the breather side to the intake manifold too eh? coudl i just bypass this and run a breather on both sides of the valve cover? thx alot
oh and my new pcv dosnt seem to even be a valve its open whether your sucking or blowing... shouldnt it shut if your blowing into it (aka turbo making boost pressure in the intake manifold)

its gonna be squirted. i ended up putting a block off on the pvc valve and then put a breather on the other side and caped my intake manifold taps. i think this will also keep from any odd idle issues that may occur if my valve cover leaks air or somthing. just less issues and less work for me i like to simplify where i can.

The pcv is there to help remove water vapor and other combustion byproducts that make it past the rings. Not running one is asking for longterm damage to your motor. There is a reason Mazda (and every other manufacturer) goes through the trouble of putting them in, as opposed to a couple of vents. Also, the MS couldn't care less if some air "leaks" in at idle, it doesn't meter air the way that the stock ecu does. Finally, if your valve cover leaks air you have bigger problems than idle issues.
Put this valve in the stock location, a small breather on the drivers side of the valvecover and you're done.

definitly run a pcv valve, for the above mentioned reasons. there needs to be a small amount of vaccum and air flow in the block and so the PCV AND the other hose need to be used...another club member had oil smoke issues when he used a "breather" filter. i told him to put the hose back on, and guess what..... no more smoking......

Right, because pressure builds up in the crankcase, and just venting them to atmo. is not always enough to rid the crankcase of pressure...hence plumbing the breather port to a constant source of vacuum.
This also helps the rings seal better which will give make the engine run better in the short-term also. On old drag cars and circle-track cars, they sometimes run vacuum pumps to get even more piston sealing and crankcase vacuum going. They see 2-3% more horsepower when running vacuum pumps (think 30hp on a drag engine).

if you say so. i guess i need to figure outa way to make my valve a 1 way valve... i dont see way they would even call it a valve if its not a 1 way, then its not a valve.
so that right?
