So when the skirt came apart you don't feel that it damaged any major components in the engine? Is the skirt visible at any point in the rotation of the crank where the remaining skirts could be inspected or are they as likely to fail now as this one?
If I hone out the cylinders assuming they are not scored or out of round should I replace all the pistons or do you think that the others would be fine? Obviously I can pull the bearings and look for scuffs on the crank. If I remember correctly the bearing material is softer that the crank so that it does not score the crank and so it is possible to have some wear on the engine without damaging the crank. Is that correct? I have a set of Mituyo Micrometers and can check the journals of the crank to see if they are still within range.
However if the block is damaged will the 1985 block interchange that is my only question because if the block is damaged and it will not interchange then we will have to delay this project indefinitely due to funding.
