Well I thought I might get my engine back together today but as luck would have it the piston rings I got were for something else.
I was busy cleaning my wheels while my buddy, who insisted on helping me today, was going to put the top end of my engine together. He checked the ring end gap, installed the rings, then the piston on the rod. About that time I asked, so what was the end gap and land clearance? He took a big gulp of his beer and says, end gap was .008†so it’s good to go and I didn’t check the side clearance because I've never seen one bad. Wrong answer I said, now don’t put the cylinder on before you check the clearance. He grabs the feeler gauge and says, fine I’ll check it. About a minute later he says, damn, there bad! I thought he was screwing with me until I double checked and sure enough they were way off. The oil ring was .022†and the compression rings were .007â€
That’s why I always double check everything and trust no one. These rings were supposed to be a replacement for OEM P/N 13010-087-023 that I got from a feebay seller with a good reputation. The original CT ring thicknesses are .045†on the compression and .097†on the oil rings. You can see in the pics that the new ones are too thin and, must be for some Chinese clone engine.
