Russ, from what I hear it will cause all your seals to swell(leakers or not)and the good ones will wear faster than normal. But you might stop your leak. Also from what I hear if you add it once you will thereafter have to add it all the time(oil change). Oh you might clog some oil pasages as well. I may be way off base so see what other people have to say. With your low milage you can probably get away with it. When you gonna do the seal by the way?
