Pair 1200 Xl Engine Damage

[kcimroccm]

I Had (1) Of The 1200's Go Down About A Month Ago. No Compression On The 3rd Cylinder. I Also Had My Other 1200 Go Down Last Week With The Very Same Problem. I Have Removed The Piston From The Cylinder (see Picture) From The Fisrt Engine. My Questions Are, What Could Have Caused This Type Of Damage, And Has Anyone Had Any Problem Changing Oil To Valvoline? Any Information Will Be Appreciated.

That looks like water ingestion, real bad. What were the circumstances of the failure exactly?
