PCV system on 383 4bbl
well AJ that is where I thought we might be heading...for Trailbeast, the air from the air cleaner housing to the oil cap via the hose is not filtered air - it just enters the hose from under the air cleaner housing - however in a reverse flow situation, I can see where the air going from the oil filler cap back to the air cleaner housing will end up getting filtered as it gets sucked through air filter into carb. So that makes sense AJ sir. My oil filler cap is vented and allows air to enter though it to the crankcase, creating a flow through to the opposite side and the PCV I suppose. The filter in the oil cap should catch any crap that might 'spew' in a reverse flow scenario in WOT should that happen. The unused nipple on the air cleaner housing just lets some additional air into the carb. I attached a hose to this nipple and ran it to the grille with a funnel on the end to get he benefit of some cold rushing air into the air cleaner albeit a pretty small amount..can't hurt. OK call it HILLBILLY RAM AIR!
