I go by rod placement.

If the rod is in the motor = motor good

If the rod is on the floor = motor not good

j/k! LOL

Nobody seems to want to be the first, so I'll start it so others can, if nothing else, criticize me. hehehe

1) Record all your runs and after X runs replace valve springs, after Y runs replace other high stressed items etc. (experience plays the biggest part here)

2)Watch your (corrected) runs to see if you are slowing down. This will tell power production but not fatigue.

3) If you are slowing down, do a leak test to see if cyl pressure loss is the reason.

4) If you scatter a motor, not only find out WHY it broke, but make note of how many runs were on the part that started the chain of events which resulted in a broke engine.
(if I only changed those valve springs at 50 passes instead of 100, it wouldn't of floated the valves which kissed the piston, breaking it and letting the rod destroy the block)
