The M112 engine has zero lash hydraulic lifters. All you have to do is pull the respective rocker shaft & replace the rocker/roller assembly as long as the tappet surface on the lifter is not damaged. Rocker roller failure is very rare. These things are built like a good racing engine.
You might just have a sticky hydraulic lifter.

thank for the in-put.
only after it warms-up, there is a tapping/clicking noise in front of the motor it is more center of the engine. as i mentioned, it sounds sorta like a rocker not lasehed properly in a older car that had rockers/lighters...
so i am taking it for granted, it is a cam bearing
