no, but not sure what the piston to barrel clearance should be for an LC but that looks to much think it is 0.0020 thou but I am sure an LC expert will come along soon

Its not moving side to side as in worn bore, its either small end or big end movement
The piston is turning if that makes sense

Definitely shouldn't do that, you'll have to whip the cylinders off and investigate further... :-\

Think you may have a problem there!! Small End broken up maybe. Strip it down carefully and have a look.

Make sure you stuff a rag in the case before removing the piston to avoid fragments dropping in the crankcase.

What the hell in for a $ in for a £

Pistons were like peas in a pod, most of the movement was in the small end
but also some play in crank. At least its still on the standard bore
