#1 cause of engine damage is dirt getting past the filter. Change them often (or clean the old ones with oil bath)
#2 is contaminated fluids. Typically people "forget" to change the transmission, differential and hydraulic fluids. Water builds up and rust never sleeps. Extreme cases of water freezing and breaking the casting.
Other than that, just keep the grease fittings in use.
I rebuilt a 1960's ford that the previous (idiot) owner started with ether and blew the ring lands off and scored a cylinder. It had well over 10,000 hours and would have been "no bore" except for the scoring.
The old ones typically had heavier blocks, larger bores, longer strokes, operated at lower rpms and less hp / cu in. All those things lead to dramatically long lives when maintained. New ones are lighter, smaller, make more hp / cu in but operate at 2x the rpms. You do the math, a new one running 5000 hours at 3000 rpm is equal to an old one running 10,000 hours at 1500 rpm. That's the biggest thing on why the old stuff lasts longer.
