I just did the upper end. Took rods & pistons out and checked rod throws on the crank they were standard, didn't do anything to mains since the oil pressure was 35psi at idle. There was no wear on the bore. I have seen other engines with a wear lip you could hook your fingernail on but this engine had no wear at all. I honed the cylinders good, cleaned the pistons, installed rings then slipped pistons in cylinder.
I only have one very small water leak at the top of the water pump where the sensor for the temperature guage goes, just a little tightening.
