The fact that the problem only exists when hot suggests that the clutch is not totally disengaging, and my experience is that there is usually some very slight 'drag'; it can be caused by dirty splines not allowing the driven plate to float free in the disengaged position. When the gearbox oil is cold there is no crunch because the gears do not turn very easily; when things are hot the free turning gears can crunch. Positive gear lever movement reduces the crunch to a minimum.
