    Stop leak is mostly oil itself, but you're wasting your time, it probably won't work.

    all it does is swell the seals,to much in my opinion is any.get the leak fixed properly by a mechanic and then you wont have to worry about it.a leak will turn into several if you keep pumping that crap into your'e engine.

    how much is too much? uhh... any bit of stop leak or any additive that's supposed to stop leaks or fix anything is too much, if it's more than one seal that's leaking check your PCV valve that is a very good indication of a stuck closed PCV valve.
