Sorry I didn't get back on this sooner and apparently nobody jumped on this question, I forgot all about this thread. I do not know if the motor has to be replaced for that. I'm thinking if you're talking about the gasket that seals the pan to the skirt of the block than you might be able to jack the engine up and drop the pan, put ceran wrap over the top of the pan so no junk falls in it when you scrape the skirt of the block clean to put the new gasket on. BUT I do not know what kind of clearance is between the pan bottom and the K frame that the engine sits on. You can just get under there and figure out that issue yourself, if you think you can at least drop the pan 4-6" from the bottom of the block with or without the engine being lifted up, GO FOR IT!:thumleft:
