[6pack] TR6 Engine Failure

[Glenn Franco]

Group
I just tore down a club members 74 TR6 engine rebuilt by the Roadster 
Factory back in 2002.
It appears that the circlip that holds the wrist pin (gudgeon pin) in 
position was not seated properly.
Looks like they did a nice job on the rebuild, but the wrist pin 
hammered the cylinder wall and I need to overbore the cylinder or sleeve it.
Have any of you experienced a failure like this.
The pistons were new A&E and the oil rings were cast iron and of course 
they came out in pieces.
Thanks in advance
