It's your e Bay fabbed valve covers. The baffle isn't efficient, nor does it block the slosh oil in the most oil-pooling part of the head.

Extending valve cover baffle. Thoughs?
I simply took a piece of tin and pop riveted it to that baffle, in the same shape as my cardboard template. I bent the part on the back side of the baffle upwards. So it blocked the slosh. Oil vapor has to travel halfway up the cover to vent...so actual oil doesn't make it that far. If someone was thinking, all the valve cover company would have to do it put the breather holes on the front.
My brother in law has cheapo chrome ones with both holes on the front. Doesn't huff oil at all.
