I'm still trying to hunt down a noise in my engine (quiet at startup, progressively louder as engine warms). I removed the op sending unit today and hooked up a mechanical gauge. It read 75 at startup and stayed there for about 5 minutes, then slowly worked its way down to 52 at 1000 rpm. These are the same readings my electrical gauge gets in the cab. Its a fairly stock engine. Is it a red flag?
