In the top picture of post 2 is that not a crusty copper tube I see breaking thought the lifter bores? Or is it just some crusty crap in the gallery?

If there is no tube in there I have no idea what they were doing.

If you are going to do any oil mods, spend you time and money on the inlet side of the pump. Unless you are turning 8K plus, that stuff after the pump is just busy work.

Work on the inlet side of the pump. That’s were the restriction is, and it’s the best bang for your buck.
