I had similar problems with my twins on one engine. Fair oil pressure when higher RPM's but entering a bay and easing back on the throttles. my port engine would drop oil pressure to 15-20 psi . It happened over one season. Had a chat with American diesel, and they suggested the oil pump. Whipped the engine up in the air and changed the pump. Viola! incredible pressure after that. Sounds like pressure is to low anyway, and at min recommended.
