I assume they have a different adjuster for each application? I'm trying to get set up for pushrod oiling, but the adjuster is hollow. I've been playing around with restricting a set of Comp 892 lifters. It was built with the lifters having a .062" hole and that was enough for oil to spray the inner fenders like a hose. I'm down to a .020" hole and it still has too much oil coming thru the adjuster. Not a graden hose spray anymore, but a small,steady stream that still pools up in the cylinder head.
