To be honest I think they've used the word "piston" either because they assume you won't understand if they told you what the real problem was, or because they have no idea themselves and they needed something to tell you.

If they're going in with a borescope, though...

I'm presuming they've done a compression check and found one pot way down. In which case, it's either piston (inc rings) or valve.

Diesel MOT's have been known to damage engines when over revved, but blame VOSA not the garage for that.

If the engine gets damaged from being revved high for the MOT then either the governor / rev limiter is set too high or the engine has became fragile with age
