High Oil Pressure

[wb4oqx]

My YM2200 came with only one guage - for water temp. The oil pressure sender is connected to a warning light that comes on when the pressure is low. The oil pressure is adjustable on many Yanmars, but not sure about this one.

I emailed a GM mechanic friend of mine about the high oil pressure problem and he said the only times he has seen it was from "spun" bearings. I would guess, the opposite of worn bearings causing low pressure, the spun bearing would block an oil port and send more pressure to the sending unit. At any rate, I wouldn't run it, except for cranking with compression release engaged to help trouble shoot.
