Wet sleeve explained

[Curt Sprenger]

Mike,

Agree on the what-if-avenues. Ron should have posted that information. Maybe I missed it. Sorry if I did miss it.

Before we go down too many what-if avenues on this, Ron told me early

on that the DD shop thinks the compressor coolant lines burst causing

a loss of coolant. The loss of engine coolant resulted in overheating

and ultimate loss of the engine. I am sure Ron will be around to

verify if that was the case or not when he gets some time to check

in. Those compressor coolant lines have been the topic of much recent

discussion and I think it is time to check mine soon!
