I crank up my truck I hear a tapping noise on the right side took the belts off an the noise still there anybody know where the noise could b comming from

Does the noise go away after 30 seconds or so? If so, piston slap

Could be a spark plug that has backed out and is about to launch any second ripping all the threads of that hole with it

Could be a header leak

Could be. . . .

.... a bad lash adjuster.......

Take a length of heater hose and stick one end at your ear and the other can be moved around to locate where the noise is coming from. Go from there.

If it goes away when warmed up, timing chain tensioner.
