They got experts in here? Dang! I didn't know...unless you're talkin about Bucket...he seems to know a bunch of stuff. Or maybe Bruce knows..or Rick maybe?
What about Robyn?
I feel like this may be a trick.
It's not gonna change a damn thing if it is.
Looking at a SBC V8 from the front, the crankshaft rotates clockwise. It weighs a bunch and has big assed weights hanging off of it, yes? Yes. Displaces a lot of volume
inside the crankcase and it spins. - It moves a lot of air that must have somewhere to go.
As it spins up the passenger side, those weights are
pushing air. As it spins down the driver side, those weights are
pulling air. Into and out of the engine for example's sake. Read this as
ring seal.
Ring seal contains the horsepower made in the combustion chamber. Keeps it and contaminate (blowby) from entering the wet sump oiling system. This is both the
why and how there is a PCV on one side (driver) and a breather on the other (passenger)
Rather or not that is true, that is how I think of it. Do a simple test for yourself.
Put a pcv in both valve covers , tell US what happens.
Conversely put a breather in both valve covers and tell us what happens.
PCV valves make horsepower because they -
improve ring seal and reduce blowby.. They introduce vacuum into the crankcase improving ring seal. Dry sump oiling makes more power creating more crankcase vacuum than a wet sump.
Ever wondered why some drag racers for example utilize vacuum pumps? They are sold in Jeg's or at Summit...INDY cars operate under negative crankcase pressure in example..there's no breathers - it's all sealed.
Look I don't know much about it but I think it's cool you asked me. Thanks. I'm certainly no expert and any number of those dudes prolly knows better than I. Maybe you'll get some other help later.
