Silicone Rear Main Seal1968-1988 Ford 429 and 460 Big Block Repairs a Leaking Rear Main Upgrade for Rope Seal Equipped Engines Direct Replacement for a Rubber Main Seal Injection Molded for a Precise Fit Silicone
Getting to the rear main on a 429 or 460 is a pan-off job at best, so it is worth doing once with something that will not harden. Silicone handles the oil temperatures a big block runs at, and as a moulded two piece seal it locates properly in the cap instead of being packed in like rope.
