Low oil Pressure at idle
I have a freshly built 20B with a brand new oil pump and internals. When I start the engine, I have great oil pressure readings (30-40 psi). After the engine warms up to operating temp, the oil pressure drops (18-22 psi) at idle. I am a running SPA oil pressure gauge which I am reasonably sure is accurate. I have dual oil coolers only (no mocal oil thermostat). Any ideas? it has plenty of oil and is not leaking. I dont know if I a missing something.
