Dreaded Effing lifter tap......

[Blackcar]

No. When the lifter is collapsed the distance the pushrod travels is less, there will be no valve to piston contact.
I did a lot of research when my lifter collapsed.
It is the geometry of the pushrods and placement of rocker arms above the valves. They do no push strait up and down like an old small block but instead have a pronounced angle that works 'fine' until a lifer collapses. The gap created from the collapsed lifter causes the pushrod to bend in very short order.
