Crankcase Evac Pump

I'd try another breather on the other side..if you have a push in breather with the 1/2 hole in the bottom get rid of it. then weld a couple of 1 1/4 tubes in your valve covers and get a couple of push over breathers,I'm pretty sure that will relieve most or almost all of your problems..
I'm even pretty confidant that after 50 to 100 miles of street driving that the ring seal will improve..
