could it be the hydraulic valve lifters readjusting themselves?

during the first few seconds of startup, if the hydraulic valve lifter reservoirs are not full, they automatically readjust, and before this is done, there is some play with the valve tappets, resulting in the tapping noise.

i believe this is normal.
