can i remove my pcv valve and replace it with a breather filter. they look much cleaner and i could just cap off where the hose entered the throttle body.

 

Sure. Works fine. But someone is bound to post about the 'dangers' of not having a PCV, so you might as well research.

 

i tried to search the topic but my skills are not up to par and i cant find the threads that would include the neccesary info.

 

Yeah, most searches only yield threads which say "DO A SEARCH" anyway. As I said, short answer, no of course not you don't need a PCV. However, you must understand that PCV stands for POSITIVE CRANKCASE VENTILATION. Lamens terms? It sucks all the oil vapors out of the crankcase (which includes blowby). Basically, your oil will probably last longer than if you didn't have it.

Also, sometimes breathers spit. You might have to wipe off your valve covers occasionally.




I wouldn't sweat it. I'd rather run a PCV because it's "active" versus a breather. Yet, I'm using a breather jsut because it looks nice. BOWTIE LOGO!!!

 

breathers work and think about it breathers have been around for some time.
usually though the pvc system is a lot better I would think
it as was stated activly sucks out the vapors.
those vapors include thinks like moisture, blowby, and stuff like that the none goodies that you would like to remove from inside there

also it has another little side effect of better sealing if it the effect is only marginal.

the lower you can get the crank case pressure the better those rings will seat


and this I'm assuming so take with grain of salt but would also think it would reduce windage losses
but again take that last statement with a grain of salt

 

in additon to what has been said & because the PCV system does remove moisture & the unburned fuel that that gets into the crankcase with the blowby, not only does it make the oil last longer, but your motor will last longer too. my vote is to keep it.

 

Keep it, even in the old days cars had a downpipe that went from the valve cover down under the car and as the car was going down the road it would create a small vacuum to help clear the engine of fumes. Racers use a tube connected to a header with a checkvalve to act as a PCV too.
