Is there a known brand/part number for a 455 timing cover crank seal (not the rope seal) that can be sourced locally or do we still have to order them from TA?
From Memory, 450446 https://www.amazon.com/National-Oil-Seals-450446-Seal/dp/B001OD7HF8 If you are replacing a rope seal in a stock cover, you need to do some mods to the timing cover before you can use the neoprene seal. https://v8buick.com/index.php?threads/front-neoprene-seal-install.308861/#post-2566926
I purchased a front seal from Autozone recently for about $13 and they delivered it for free. https://www.autozone.com/internal-e...63/226821_0_0?searchText=Duralast Seal 710163
