I did the engine build myself, and can say with 100% certainty that the piston did not get damaged or dropped during the installation. In any case, it would have been pretty difficult to only damage the ring lands below the top ring.

A faulty piston casting is a possibility, and I really had little interest in exploring that avenue, as it is not as if Ford would give me a new piston, given the modified state of my engine, but as with all high silicon (sand) aluminium, strength is unpredictable, as silicon distribution can be a bit uneven. The good thing about this type of damage is that it does not destroy the engine, but only drops compression on the affected cylinder. Doesn't change the fact that engine has to be rebuilt though :no:

Finally, ring gaps were XR6T factory standard, as these pistons and rings came as part of a complete short engine, where I just replaced the con rods before assembling and fitting to my car. All pistons were marked before removing, and fitted back to the exact same bore they came from.

I was running around 300 rwkw and was heading down the strip when this happened, causing a careful limp home......

Hey Ninka,could it have possibly been a faulty piston or it was dropped or mis handled when replacing rods?? Looks like a pretty clean break.
