I have a motor that I picked up from my friend. He left the spark plug wires out of the motor and it sorta sat there for a while, so now the motor cranks but it won't turn over. Another friend told me that the piston rings might be dried up and dropping a couple drops of oil into it will fix that. Does that sound reasonable?

 

That is a good idea, many people do that to a motor that has been sitting for a while. You may want to use more than a few drops though.

 

Put ATF in each piston and let it sit for a few hours then try in turn it with a socket on the pulley bolt. to turn the crank. Automatic Transmition Fluid If you didn't know.

 

Okay cool, I'll give that a try. How much would you recommend me putting into each piston? I don't want to put too much, or too little.

 

just enough to surround the outer part of the piston where the rings are so it seeps down their and soaks the rings.
