Re: 156 lost power
It may be intact but not moving ... often the belt looses teeth so it gets to the gears on the crank and stops. unfortunately as the pistons keep going, the valves take the brunt and get damaged. It's the "loss of power" comment that make me think it might be the belts.
If the starter sounds quicker than usual, it may mean it's still trying to turn the engine over, but because the valves are bent, there isn't any compression so it spins more easily.
Otherwise if the starter is spinning at very high speed, the gear on the end that engages with the flywheel may have got stuck.
