When to worry about engine noises?

Lots of good suggestions here... you guys really have me thinking about the oil selection



I see that on the web page. There's also a pamphlet that came along with the engine that listed Rotella as one of the acceptable oils. No way in hell would I pick this diesel oil on my own!

Doesn't explain the low oil psi though.
40lbs idle and 65lbs At freeway speed is what I expect.
Noise. Change oil and then see IF the noise is still lingering or gone away.
I wonder what the bearing clearances are in that puppy. If you get the motor real hot 'some people do and don't even know it' ...like a misreading gauge or sender...the oil pressure will drop as the oil viscosity drops to water .
