Feel free to correct me if I'm wrong, but from my understanding, the PCV has little to do with RPM and more to do with vacuum. If you have a LOT of vacuum, at idle or whatever, the metal in there may be sucked clear to the top, and with no vacuum (WOT), it may sit in the bottom.
However, it's just that it "may" do that because the crankcase pressure it's bleeding off will be changing. There may very well be enough crankcase pressure to push it open at WOT, and there may be not enough vacuum to suck it all the way up at idle.
This is just my understanding of it; I may very well be wrong. But based on what you said, to me it sounds more like it seals up fine under low amounts of oil pressure, and as you go up in pressure it starts to leak. Not really sure what would cause that, other than maybe a seal that seals up ok but not perfectly.
My pcv sits sideways. Not up or down ? Should it be pointing up ? The way its made it looks like it should be sideways like it is. But im not sure.
Its like a t fitting pcv. Small vacuum ljne on it goes to a cto i think or maybe the charcial canister ? I csnt remember off hand.. and it lays sideways.. one end nearly directly in the csrb. Thr other hose turns left into the intake.
Ya i blew into the open air oil cap.. it blows free. I breathed into the pcv line in the intake too.. its free. Pcv is super clean it does rattle at idle though. Can even hear it in the cabin.
Yes it can idle at 1000rpm in park for hours.. and never leak. But at 2000rpm. Itll leak.
None of the dang auto parts stores have the fsctory yellow oil breather cap. I was gonna run a line to my edelbrock air cleaner like factory and see what happens. Im just curious is all.
So i gatta order it online.. couldnt find mine in my parts anywhere.
I need to pull and luah my bakencer like people keep telling me... I dunno if its thst though as my bearings were in such good shspe.
I also discovered two upper transmission bellhousing bolts ti the engine are so lose the washer can pivot.. i gatta figure out how to get a socket back there and tighten it
