Seems that when my engine builder/best friend built my O-290-D, he used iron rings in a non-chromed cylinder.
These have worn remarkably in just about 80 hours - compression was 20/70 in all cylinders, so I pulled them and found ring end gap to be in excess of 0.125 - normal is 0.020 to 0.030. The rings are also quite knife-edged - enough to slice fingers!
Luckily, there was little or no cylinder scuffing, and the pistons are fine.
So - I need a set of chrome rings for my engine, standard or 0.005 over. Any leads will be greatly appreciated.
