Sounds like way too much oil to the top end !!
Took the words out of my fingers.
possibly. it's an Indymaxx block & they dont have huge holes for oil to return from the valley. I have opened them up & contoured the openings to improve drainage. Before we ran a chute we would see maybe 10-15cc's of oil in the puke can breather. So i can't change the block anymore than i have & we don't have a lack of oil problem at the pick up, so i'm looking into an air/oil seperator to fit before the pump. anyone got one of them?
