OK, That's done.
The oil analysis is subject to interpretation, and since the oil wasn't warm or freshly churned up when the sample was taken, and there is no baseline history of the oil analysis, there is some room for leeway......
However....
With a viscosity of 13, I've got a feeling that the engine was overheated many times, or the oil that was used was whatever junk the PO could find at the Dollar Store for 59¢/quart.
The Iron levels are within acceptable tolerances, however, I would be concerned about piston scuffing with the use of the wrong oil. Iron could also be caused by rust in the cooling system from running too low a level of antifreeze.
Copper Content is a bit high in my opinion, considering the condition of the rest of the engine, meaning bearings or injector tubes are worn or leaking. This could also indicate the radiator is flaking from the inside, (unlikely).
Chromium is acceptable, at least within the parameters of how the sample was obtained, but I would only expect worn rings, not broken ones.
Now the biggie.... Coolant in the oil.
We've all pretty much guessed that the O-rings in the head are shot, but with the other readings, it looks like it's entirely possible that the engine has one or two cracked heads. Owwwie! That's gonna hurt. there could also be a leaking oil cooler in the mix, but not likely.
Now... Bottom line...
It looks like the engine could benefit from a minor overhaul and general freshening up, along with putting the original fan back together so that it cools correctly.
I have one head gasket set, need another at the very least.
I have a blower seal kit to replace the bad ones in your blower, (Another Problem not related to the overheat).
I have an extra oil cooler element and housing that is in good shape.
I also have lots and lots of other gaskets to stop some of the leaks that DD's are famous for, along with other misc. spare parts.
What may be the show stopper is the need for a pair of heads, I don't have any.
I would also look into a set of rod and main bearings... I have a couple of sets, but don't know if they are the right over/undersize for your engine.
So far, we've had 2 donations to the
Get Doug and Family back on the Road Fund, one for $50 and an other for $100. The one for $100 was withdrawn with no explanation.
If I bring the bus down here, it's going to be a long slow trip, to try to keep from doing any more damage than has already been done.
Let me know what you would like to do.
