I have the Original Rolls Royce IO360 engine in my Skyhawk XP, it's done 1900 trouble free hours (1300 flown by me) and still has near perfect compression.
Your luck is much better than one I know of. This one aircraft had three totally separate in flight engine failures due to mechanical reasons that could not have been predicted. The last one at night in IMC killed the two occupants.
If I recall correctly there was a different engine fitted between at least one engine failure as an exchange overhaul and at least a bulk strip/overhaul on the other occasion. The failures couldn't be attributed to lack of maintenance
It also had numerous other "minor" engine issues, like sudden low oil pressure requiring an immediate landing.
You couldn't pay me to own one.
Yours must be a fast one, I never saw anything much over 120 in the ones I have flown, in fact they struggled to go much faster than a PA28-161.
