Yes, look in the "Diesel Engine and Drivetrain" section.

if i have him run a compression test again is there a preferred method?? wet/dry?? how long or little to have the engine sit before testing??
Test dry first, then pour 1/4 teaspoon motor oil in each cylinder, retest "wet," compare. GET THE NUMBERS FOR EACH CYLINDER FOR EACH TEST.
If the engine has been sitting several months or years (looks like may be your case?) the piston rings can dry out and not seal well until oil is introduced to help them seal again. Results in (dry test) low compression.

i hope that is not too blasphemous of me to admit to here on this forum
but i am eager to learn!!
We will try to help as much as possible. WARNING: Major time and effort investment!

Yes that is the correct expectation, glad you recognize that!

General Observation: You mention your mechanics. Do they have plenty of experience on these D24 engines? Or (2nd best) on VW diesel engines from the 70s-early 90s? Otherwise, we can almost guarantee they will destroy the engine, lacking the necessary (and getting harder to source) special tools, and equally necessary special knowledge. Sadly, have seen it happen too many times.
