Hi all, I am new here and looking for some knowledgeable Healey co-enthousiasts. I need help on the rebuilt of my BJ7 engine. Does anyone know what are the tolerances on the cylinder size (originally 83,34mm?). The gap in the piston rings is too large (.55 mm) so I wonder if I need to enlarge the bore or just replace the piston rings. Thanks in advance for your help! Walter
