That reminds me of when I was a boy. My dad had a Viva van, and the engine was knackered, so we took the complete engine for a re bore and crankshaft re grind.
It came back as a box of bits like that. It was "fun" putting it back together, having not taken it apart ourselves, but we did it, and the van ran for another 2 years before the tin worm finished it off.
Told to me by my daughter - so it must be true! :-
Friend of hers manages a car-hire depot. Bloke picked-up a brand-new small Renault on Friday night, brought it back Monday morning, said t'ra to staff and walked away.
Mechanic servicing the car later that morning found an old crap engine under the bonnet in place of the new shiny one.
"The bloke" had given a false address and driving licence details................
++++!My least appreciated phrase to encounter in the old Haynes manuals was that "reassembly is simply the reversal of the disassembly process". Like Hell.
