Well this is what happened to my 240 to necessitate a new motor.

The mileage is near 300k on Scar, but that motor sounds smooth! When we picked it up, it had been sitting for quite some time and just fired off.
I'm pretty excited that I'll be dorking around in the 240 within a few weeks. I'm going to reseal the motor, new clutch, etc.
Pics of the swap will follow
