What are his thoughts? Did he diagnose the oil pump as the culprit?

Yes he did, after checking all the actuators etc and manually testing oil pump, but completely baffled by situation.

Sounds, to be blockage in the oil drains in block,if oil pump went out,there may have been cooked oil in the ports,therefore blocking the oil from circulating.

2 out of 2 people think this is helpful.

Would this continue after engine hot, would this not rather be the case if engine cold. Please advise remedy to unblock. Thanks so much as we at our wits end with this vehicle !
