The truck has around 45000 km and engine hours match KM. Truck is parked everyday in a heated shop. It was on a run up from Red deer, just passing through Leduc and started running rough and smoking, then power dropped right off and he limped it into us at 20 K/Hr. After diag, #7 low compression, pull head and piston is grenaded to the point that you can see the second compression ring. The head is also damaged. We found a split injector tip also, barely visible with out aid. Just over time for Ford warrenty and they denied any assistance.
Anyone have an explanation as to what may have caused the concern?
I have heard of water getting into the fuel system and splitting the injectors, but this fuel system is spotless.
