Thanks Longtrman. I'll let you know about your parts offer. The pistons are still connected to the rods and the top of the each piston is clearly marked "front". If I understood your point about rod caps and tangs correctly, this should take care of that problem. Based on the overall condition of this engine I have no plans to overhaul the pistons.Tym , I have a 172-6008D gasket set that has been on the shelf for several years ($30.00), .010 rod insert set ($25.28) .010 main bearing insert set ($41.34). All are Tisco. McCord made the head gasket and Clevite made some of the bearings. You would have to pay UPS freight charges and UPS C.O.D charge in addition if that would help you any.
When you go back together with this engine be sure to put the rod caps on the rods with both tangs together. If you put the cap on backwards it will lock up the engine. I have already found two ford 172 engines that the factory had made the rods wrong. I believe that the I&T manual will tell you to go by either the identifiaction numbers stamped into the rod and cap or the words on the cap but instead look for the tangs on the inserts and put them together. Also if you use the seal sticks that seal the side of the rear main bearing cap install them as stated in I&T. Most of us no longer use the factory seal sticks at all. We use heavy cotton packing string driven tightly into the hole with a slender punch until the hole is full of packed string. Be sure to stagger the ring end gaps. The rings will rotate on the pistons somewhat but start with them staggered. I would like to see you have the crank tested (Magna fluxed or dye tested). When I was young I carried a crank into the engine shop to be tested. The tester picked up the shaft, set it down on the rear end of the shaft on a concrete floor and pronounced it bad. When I insisted he show me, Magna flux showed a crack I couldn't see. He could hear that the shaft didn't ring when it hit the floor.

I am curious about the cotton packing string option though. So, you just pick up some heavy gauge cotton (from automotive supply? craft shop?) and just pack it into the gap, huh? Sounds simple enough.
