I would think this puts you in a strong position as almost certainly the dealer should get compensation from the rebuilder, and thus has less to lose by compensating you.

infrasilver said:I think the reason for the catastrophe is clear regarding the clip but why it took so long for it to fail is a mystery, I could understand 50-200 miles before it went walkabout but not sure why it would last a few thousand miles unless the clip simply failed or was misaligned but still held in somewhat, there isn't really that much sideways pressure on the clip.
infrasilver said:I have fitted new clips and also re-used clips as there is no strain on them at all when installing and could be fitted a ton of times before any fatigue would occur. I just think the clip was misaligned on install and has took this long to shift.

Two reasons. 1) It had been "run in" for several thousand miles with a low rev limit which would limit load on the wrist pin and 2) This bank had cast iron liners fitted which when faced with a hardened steel wrist pin will last way longer than a coated ally bore especially when you consider the pin is below the oil scraper ring so this area has good lubrication. It can take a surprisingly long time for a pin in an iron bore to wear it to the point that it picks up.

It's more likely whoever removed them the first time over compressed them in doing so which slightly reduced their overall diameter. This diameter is critical in their ability to lock the wrist pin in place. For such a cheap component that has such a catastrophic failure mode it's best practice to consider them single use.
infrasilver said:I'm not disagreeing with you as I can see this has happened, the gudgeon pin (I'm in the UK) has sat there going up and down with the bore holding it in place, I get. I'm not sure if you know the whole gudgeon pin actually fully clears and goes about 2-3mm lower than the skirt of the bore at its lowest point, it hasn't picked up on the bore but gone below it and this is why I'm confused it lasted so long and had not caught the bottom of the bore earlier especially after all of those miles.
The only thing I think it could be that the speed at the bottom of it's stroke is so fast it doesn't allow the gudgeon to shift over any before once again sitting against the bore wall, maybe it had chipped away at the bottom of the bore, bit by bit until one day it just caught and that was the end.

I once asked a dealer this as he proudly explained the terms of the complimentary warranty and invited me to upgrade to 6 months. He just looked at me blankly!

For our own protection, can you find out who did the rebuild (so we can all avoid!!!)?
scarletboarder said:The dealer who sold it to me on 05/08/16 was the one who had the rebuild done. The son then used the car for the time in between. The car is back with the garage that did the rebuild and I await their report. I haven't contacted the dealer yet. Phil.
