I am replacing my JE's at only 140 hours. Normally would go much longer, but I had a problem with porosity in my Merlin heads and had water seeping into the combustion chambers, turning into steam, and superheating the oil. The engine builder saw some signs of premature metal fatigue in the skirts and recommended replacement.

If 2 are needing replacement, then I agree to do them all. Chances are that you'll need some overbore for the 2 new ones and will need to do them all anyway.
