It has been running good, then two days later clicking sound in valves and oil pressure gauge keeps dropping below 40 into the 20-15 pressure. Is it time for new oil pump or is it serious like the bearings?

It cold be just a bad oil filter for one. Have the engine manually checked for oil pressure first.
