10 year Refresh 65 Valiant

Double check your rod bearing clearances. If the engine only has 14,000 km on it something isn't right. Those bearings look more like 140,000 km. Are the shells showing copper from the connecting rod side or cap? If the rod side is down to the copper it could indicate you have been in detonation or "pinging". Maybe this happened when it was running rich? Good thing you took a look at them.
