You have to be exceedingly rough to damage a PW123 from an overtorque.
Maintenance required is:
Over 145.6% for 20sec or 127.9% for greater than 20sec, a boroscope of the engine is required.
Over 202% for 20sec down to 145% for 300sec (
) requires replacement of the Reduction Gear Box.
Unless there is damage found during a boroscope there ain't no reason to remove the engine.
And to get it to that stage you have to really give it the onions and then forget about it for quite a while - considering you guys notice one when it burps a bit - can you really imagine not noticing one running at 140%+ for 20 or more secs?
