Thanks for the suggestions. I have the other 3 mains torqued and the engine turns freely. I plastiguaged all mains without the rope seal, and had .002 clearance. I did tap the seal with a ball-peen hammer to shape the seal, and coated the seal with white grease and oil before installation. I am being told locally that I have no choice but to contunue with the rebuild, and have faith that I can get it started, maybe with a pull. I was hoping I could find a rubber seal or another option. Appreciate any other ideas.
