Or is your answer 300d starter,good battery, good glow plug system. And that fixes it?
How will this tell you the rings or valves are wore out?
Maybe I missed the point. Please explain.
Thank you.

I think part of the point is that worn, worn out, and useless junk steel are completly different things. Where as there is either right or wrong going by the book. See my account of my last 1.6TD VW, it was worn, posibly worn out, but it still served as daily transportatin just peachy up till the day it was pulled out, including it's last thousand+ mile non stop trip at a solid 3800rpm.
If it had slightly sub par starter, battery or glow plugs, then it might have crossed into the useless junk steel catagory.
I do still like compressoin tests, it's not hard to fix valve related problems, but there's more to it than "well the compressoin is low, junk it".
