The previous owner didn't change the timing belt when we was told so the damage eventually ended with piston slap and the truck needing a new motor.
1) welcome to the forum
2) it's ultra rare to have a catastrophic engine failure with a VQ40
3) there is no timing belt or replacement interval
4) there is a timing chain, which has no replacement interval, though they can make a lot of noise if the tensioner guides wear out
5) IF it has "piston slap", it wouldn't be from the timing chain. Piston slap is a term generally used to describe noise as a result of wear or damage between the pistons and cylinder walls. About the only thing I can remember causing this on a VQ40 is the result of failed catalytic converters.
6) better to diagnose a problem properly than to rely on what someone else said
