I would look at that #7 lifter. It sort of sounds like it is not bleeding or leaking down properly on each stroke and then at some point the pressure all lets go at once like the lifter is collapsing. Frankly, I'm not sure how you can test a hydraulic lifter. If you take it apart you may see something obvious like some blockage inside or one of the springs is broken or something. With most all of the oil drained out you may find that something is sticking inside the lifter like the plunger piston or I don't know.


Ok never mind, LOL. I didn't see your last post.
