Parked one evening running OK. Next morning, no start. Cranks fine until oil pressure builds, then acts like one or two consecutive cylinders fire, accompanied by a clanking noise which seems to come from the rear of the engine. No noise until oil pressure comes up. Recent oil cooler, HPOP cover gaskets, standpipes, and dummy plugs. I suspect HPOP.
Any help appreciated. Thank you.
