#1 Yes, your vacation trip may end rather abruptly and with little warning.

Broken Valve Springs

Broken or weak valve springs in an engine can cause many different drivability and performance problems. Broken valve springs cause excessive valve noise, compression loss and can cause severe internal engine damage. The actual breaking of the valve springs is not always the most serious consequence. Actions following the breaking cause the most serious damage to the engine. When spring breaks, it may collapse just enough to allow the valve to drop into the cylinder, where the piston may strike it. In addition, the valve stem locks or keepers may release the valve and allow it to drop into the cylinder, causing severe damage to the piston, cylinder head, and other nearby parts.

#2 The Ford 2.7L Turbo 'Nano' failures seems to have an engine build date range as shown here.

The first generation of these engines were also problematic, but worst issue seemed to have been a leaky oil pan. I'd prefer that to a sucked valve.

#5 After 100 years or so of combustion engine design and manufacturing, one would think engine valve problems might have been overcome.

#6 I would expect redline+ over revving to get more torque out of that tiny engine as the cause.
