SPINJIM 1,986 #1 Posted June 3, 2024 I'm rebuilding a K91 engine, and would like to replace the oil seals for the crank shaft, both output and bearing plate sides. I checked the old threads for info, but those references were all out of date and discontinued. Anyone have new sources or numbers for those seals. I'd love to have a NAPA equivalent, because I can get that in a day or two. Thanks for any help. Jim Share this post Link to post Share on other sites
