Re: defining "rebuilt"
I've found there are three kinds of rebuilt engines on boats.
Spray can rebuilds - new paint, maybe belts & hoses. Looks good but that's all.
Freshened engine - new rings & bearings in an un-machined block. valve job and any externals needed - injectors, pumps etc.
Rebuilt or major overhaul. This is what Porfin is currently detailing on his thread. In this case - a proper rebuild - only the major components are recycled, after re-machining them to be within factory new tolerances. All wear items - springs, rings, liners, pumps etc. etc. are replaced with new. High pressure pump and injectors are checked and replaced as required. The engine has to come off it's mounts for this although I've seen it done inside the boat, on the cabin sole when full removal to a shop would require deck surgery.
Only the last level of work qualifies as a "rebuilt" engine - the other two are tidied up or serviced and freshened respectively. Anything other description or representation is deceptive at best and fraud in most cases.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
