So lets think about this for second...the holes that feed oil to your crank and cam bearings are, for the most part, pressurized oil leaks. You really do not want to goo them closed. How does a stop leak oil additive differentiate between a good leak and a bad one? Just sounds like a bad idea to me. But then I'm no expert that's for sure.
I good stop leak is polite and asks the part if it’s ok to “filler up†before it does it. Lol
