It's too bad that manufacturers don't put out any specs on Mean Time Between Failures (MTBF) for conrods based on RPM and fuel consumption.

Question(s):

1. Why raise the piston to the compressed position before removing the rear plate?

2. What would cause a crankshaft pin to go out of round?

3. Sustained over revving for how long?

4. What would you consider significant overheating and for how long?

As always, thanks so much for your time and knowledge Alfonso.
