R3W7 Assembly
Here's the end result...I tapped the lifter galley for 9/16-18 then made an 'oiler' that threads in. It has a 1/4" blind hole down the middle, and a .028" hole that comes in from the side to spray oil out onto the cam gear bearing. There's no great way to 'clock' this so I fitted it such that the spray hole is in the right position when the oiler is tightened in the hole, then the shoulder of the cam plate prevents it from backing out more than about 1/32 turn. No matter where it ends up on clocking, it will spray on the bearing. I drilled the spray hole at a slight angle so it sprays back into the bearing rather than hitting the cam gear itself.
I made it this way (one piece) so there are no parts that could come loose....if this piece ever makes its way out, I have bigger problems to worry about lol.
