I've diseceted a .937 lifter just to see exactly how they oil and whats goin on inside, this is an older lifter I had sitting around, I took it out because it was going away, pretty obvious why too. I destroyed the lifter as they are not rebuildable but I knew that would happen going in. The amount of machine work in one of these is unreal, they get $115 for one lifter, made by LSM.
Here is the a pic of the guts, I'll add more as I get more time tonight and over the weekend, I found it sort of interesting.
The piece with the cup in it is aluminum and its actually a manifold for diverteing oil to all sorts of different places, 6 places actually. The way the oil gets to the axle is pretty cool, Ill post more pics and stuff later.
