Oil pressure in an engine is developed by the bearing clearances....

What civ said.

Skyline, this is all just guessing until the OP actually hooks up a oil pressure gauge and starts diagnosing the problem. But we know the engine wasn't maintained properly. And there are lots of bearing surfaces other than rod bearings.

I'd think twice about that engine flush. It will lower oil pressure, unless the only thing clogged is the oil pump.
