Hello, I have damaged my XJ600 51J oil pan thread - a real nightmare. So, in order to have the dripping oil pan sorted, I have two options to consider: 1. rebuild the thread or 2. just seal the oil drain hole and use an oil extractor pump in the future. Rebuilding the thread (option 1) would be clearly more expensive and time consuming way, since I would need to remove the whole engine to access the oil pan. The 2nd option would be rather simple, but replacing oil in the future requires therefore more "messing around". What would you suggest?
