That is not really a tappet. It is the pivot point of the rocker arm on OHC engine. It is hydraulic and does adjust clearance to zero. It does not touch the cam, well unless there is some sort of catastrophic failure. I have seen them called hydraulic lash adjusters, but there are probably other names.

Yep. That's a lash adjuster. Same concept as a hydraulic tappet, just in a different position.

Lash adjuster. If you have a dodge with the 4.7 it clicks for a few min when you start it.Normal is what the dodge guys say

I might replace mine if the tic dosent go away after I replace the bad exhaust gaskets.

That is a hydraulic lash adjuster for a finger follower (end pivot rocker arm) valvetrain. It's the most prevalent valvetrain design in modern automotive engines.

It doesn't have tappets, it has roller followers. The HLA's pictured above take the slack out of the follower assembly.
