the result of relatively minor overheat conditions. Is the water temp also
high? Could be several things or a combination of things. Oil should be
changed at least every 100 hours because carbon build up in the oil reduces its
ability to cool. Radiator could be compromised in some way either internal or
external. Have you checked the coolant level not using the sight glass? The
impeller on the water pump could be worn. You know, considering how expensive
an overheated diesel can be, I would take it to good shop and let the pro's
diagnosis it. Just my two cents worth.

Well I just changed out my oil cooler as it leaked oil into the water and made a
mess including not cooling the engine very well. The oil cooler is a water to
oil unit located just above (attached)to the oil filters. It is replaced as a
unit and is no fun to do as the bolts holding it onto the block are hard to get
at. Additionally the unit is around $400 exchange. I would say if your water
temp is not elevated then the gauge is the first place to look/hope.
