For diesels, a list would include but would not be limited to:

1. Cold inspection. Any wet liquid on or under oil pan or transmission? If so, ......Double hose clamps on raw water intake lines and exhaust lines.
22. If possible, remove the heat exchanger upstream endcap and verify that there is no debris or impeller vanes blocking water flow. DO NOT do this without owner permission or without a new gasket immediately available.

This is what I can think of for now. I'm sure that there is a mechanic out there who will provide an even more detailed list. I checked Nigel Calder's Diesel book and there is nothing about inspections or survey. Too bad.
First and foremost, hard to start in cold weather...means poor compression. Only way to tell without a compression test, and the most inportant by far of potential problems.
