    Has anyone else modified the baffle in their steel valve cover?

    I bypassed the oil separator because mild/hard accelerations would fill the airbox with oil, so I put a filter on the rear left corner (left looking at it with the hood up) but that fills with oil too under mild/hard accelerations. It's not from blow-by but oil that pools in the stock baffle slides straight into the "PCV" bung when going forward.

    I have a few ideas to improve the baffling within the valve cover but am looking for inspiration. Not too interested in moving the bung to the top side but if I have to I guess I have to..... But definitely NOT swapping to an EFI HO valve cover, does not fit with air box.

    Of course I'll keep everyone filled in as I go, hoping to come up with a brilliant & permanent solution that I can apply to all my valve covers so they can't spill/sip oil. 20190708_143237.jpg 20190708_204120.jpg

    Let's hope not, that's overkill for my tiny problem. I don't have any blow-by (fresh engine rebuild) so a can isn't necessary, just need to figure out why oil is getting caught in the baffle and not draining back down but is instead flowing into the rather low-mounted bung under acceleration.

    When I did have blow-by and a plugged crankcase pressure equalizer tube this was a serious issue, oil would FILL the air box (overflowing the separator) upon any occasion. Others with the carbed motors have reported similar issues but those with EFI, Turbo, & CFI have much better "PCV"s (actually oil separators) that are mounted higher to completely avoid the overflow-under-acceleration issue and not being carbureted they don't have airboxes that can fill up with oil either.

    I could maybe find a right-hand-angles hose to mount my filter higher vertically instead of horizontally near-flush to the bung....

    its been a loooong time since i had a 1g valve cover off.. wonder if you could drill a hole or 2 on the baffle to promote drainback

    Possibly, it would be spectacular if that's all it needed lol

    I have a few laying around, on the next rainy day I'll drill out the spot welds on a spare one and investigate. Maybe I have to add baffling, maybe I just have to remove some. I'll keep everyone posted, very excited haha
