10 lbs of oil pressure on engine break in..........

Well, im at a frustrating loss as to why i have such low oil pressure at idle, so much so that the lifters are ticking really bad and see that there is not enough oil getting to the pushrods/rockers. When i rev it up it gets to about 30/35 but thats at around 26/2800 rpm, then back to low pressure.

This is a fresh build, .20 over stock pistons, stock crank, slightly loose bearing clearances but not exactly what i would think would translate to this issue. Any insight would be greatly appreciated.

Thanks,

Jake
