Folks hoping for some clarity here...
Just installed new cam/lifters etc and noted these pins atop the injectors that are dished, to receive the roller cam rocker ball.

Goofy bit being 3 of the 4 have a bleed hole/oil passage directly in the center of the dished area.
The oddball has no hole...hmmm.
Figured its been pounded/worn shut.
Ordered new unit from dealer.
New unit comes without this hole.
So what the heck?
Are the other three pins with holes somehow faulty? The hole is machined and not from wear. Dealer techs have zero clue.
Anyone experience this?
