It all depends on where the oil leak is located. First find the source, then know your mechanical abilities, repair your self or find a person that has done this repair before to tackle it for you. There is nothing you can add to the crankcase that will stop an oil leak.
First take off the Carborator. Then for a quick stop problem pour pepper into the oil tank, the pepper will expand and plug the leak. Sounds crazy but it works.

use leak stop or something. Where is your oil leak?
I place a large clean piece of cardboard under the car when I park it, then check the board the next morning. This usually works well for any kind of leak.
You can either replace the gasket which is leaking or buy additive for oil. The last works only in cases when leaks are not severe.
There is a seal to seal the pan to the block. This seal goes out mostly do to lack of oil changes. Change oil then add a stop seal leak additive that closes off the leak with no harm to the engine. It works!
