rebuild question 225 ox66

[fastcranking]

I have a 99 225 ox66 that still runs great, but i don't know how many
hours it has on it and with the age of the motor do you guys think it should
have anything done to prevent a major problem or just run it till it blows
someday, the compression right now is 100 on 5 cylinders and 98 on 1.

keep doing what your doing. make sure you treat your gas, have a fuel/water seperator installed, and keep up with tune ups.
