dunno if it help but on the un damaged pistons does there look to be any marks where the valves have hit the pistons? If so could they have set up the timing wrong (or pulleys were loose?) then as the valves hit the pistons one gives up first and drops in, hence causing the issue. Was the car ticky at ALL when you got it back, or was everything fine???
Yep all the tops of the pistons have marks from the vavles. Had a tapping/clicking noise aswell when I got the car back the 2nd time, told them and they went for a test drive with me and said its the exhaust... And to come back on Monday
I never hit the limiter aswell.
