Default Low oil pressure making me go through bearings

Just rebuilt my engine and put an oil pressure gauge on there and when i first started the car up the oil pressure was very high almost to 80psi and it eventually started dropping due to the oil getting thinner so took it for a little two mile drive and the psi was down to 7 can anyone help me out here, I put in new main and rod bearings with the crank turned and new pistons and rings and wrist pins all new seals and the heads torn down and cleaned and also cleaned the snot out of the rest of the motor everywhere i replaced everything except the oil pump but the oil pump seems to be within clearence and the relief valve is not stuck and is funtioning properly. And i forgot to mention everything else the clearences are withing their approporiate range. WHat could this possibly be? An internal leak but there are no signs so I dont really know. Any help is appreciated.
Thanks

2.5L turbo motor?

If so check the oil pick up. There famous for cracking.

Why wouldn't you replace your oil pump? "It seems within spec" isn't a real thing unless it's been actually tested against spec. Just replace the pump. I bet your problems disappear, or you find what the problem is on the way.
