Terry,
I must say I'm confused with your statment.
A leak down test as you know; fills the cylinder with air and checks/test where (rings, valves - exhaust or intake) are leaking and by how much that cylinder may be leaking.
It has nothing to do with how the lifter is or is not pumped up.
That is another issue.
IF a lifter is poorly adjusted; a valve could be is held open or not open long enough. It would affect how an engine runs. It would either not allow compression and/or could back fire.
Sorry if I'm not too clear.

Marie and I are blessed to have had a 2nd chance to buy our farm.
Still hoping and more importantly praying to be able to build a garage.
Our 1970 Ultravan #520 has an Olds Toronado 455 in back.
