So I just had a motor built. On first start up it took longer than I liked to build oil pressure. Right when I was about to shut it down the gauge went up to about 70 psi. After about 20/30 minutes of idle time the pressure fell slowly to about 5psi. I had to pull the motor and take it back to the builder. I bought a new oil pump and he put it in, the old pump was on my last motor that blew up. The builder says the motor is ready. I really don’t want to put everything back together to have the same issue. Is there anything else I should have them look at before picking my motor up?
