First you should get a oil pump pressure test to see if pump has correct pressure. Is that the reason you put in a new oil pump engine was tapping or just started tapping after new pump install ?

the engine hydrolock ,and blow the oil out the oil pressure sencer replaced intake gasket head gasket oil pump was binding but no oil getting to the top.

Just got your answer. Try this I know it works because I seen and heard it work . Try adding some (Lucas Engine Oil Stabilizer ) to your oil. If you change your oil just leave out one quart of oil then add the Lucas. With in 45 minutes to an hour of letting your vehicle idle the tap will go away. I believe its safe to say I will guarantee the tap will stop as long as its not your oil pump.
