I’ve gone on record as being opposed to the use of these products. In my opinion, there is no such thing as a “mechanic in a can.” It’s not likely that you’ll solve anything with the use of stop leak products. In addition, I have concerns about these products causing issues rather than solving them. Think about it: If you have a leaking engine and you put “goop” into it that’s designed to seal things up, do you think it will discriminate between an external leak and one that’s supposed to happen inside your engine? To put a finer point on it, if stop leak is supposed to seal, it’s likely going to cause a buildup inside the engine as well as “seal your leak.” That internal buildup might cause more problems down the road. This is very difficult to prove, but personally, I wouldn’t take the risk. If you have oil leaks, fix the leaks, don’t try and shortcut it.
