I hate to say this but a tapping sound usually means there is a rocker (or rockers) that are not adjusted properly. Hopefully there is no damage to rockers, springs, or valves. Make a close visual inspection for anything that looks 'NOT like the others'. The manual gives the proceedure and may also require that the engine be at a certain temperature before starting the adjustment, since heat causes expansion. Try again and follow the manual EXACTLY. Practice makes perfect and you will get better at hearing what the engine is 'saying' to you. Adjustments will change as the engine goes from cold to operating temperature. The tapping could mean there is a gap larger than specified for optimal performance. In the old days some engines' valves were adjusted while running! This way you felt and listened for the tapping to stop when it was right- (not recommended for your engine). Just ask Grandpa about working on old farm tractors. I , please post with the outcome- for others to learn.
You can adjust tapping valves by adjusting the lifters.
Ticking in an engine generally refers to the valves. If ticking is apparent on a 1994 Chevy Lumina tighten the valves to factory specifications.

Collapsed hydraulic valve lifter? Rocker arm (valves) need adjusting?
Valves tapping?
Tapping valves is a noise made by too much clearance between the valve lifter and the valve. Modern engines have hydraulic lifters. If you have too little oil pressure or run the engine low on oil, the lifters will make noise. The lifter can also wear out.
You can calibrate your seat 12 Caterpillar diesel engine by adjusting the fuel valves. You will also need to adjust the fuel injectors.
