I picked up a '81 bj42 with a 3B diesel and am a little concerned about the oil pressure. I have an aftermarket oil pressure gauge which I feel is accurate and the pressure looks fine running down the road but drops while idling. Is this typical? What kind of numbers should I be looking for.
(using 15w-40 oil and in warm weather).
Also what kind of coolant temps should I expect?
Thanks,
Mac
