I would get a new dipstick also. Even if that doesn't turn out to be the source of the leak, it will help eliminate some gunk getting into your dipstick through that hole and ending up in the oil pan. I've had dipsticks stick up several inches out of the tube for no telling how long. Oil didn't blow out of the open dipstick then so I would be surprised if it's blowing out that hole.
Lay some cardboard on the ground under the engine while engine is still warm. Watch for oil leaks and where on the cardboard. If you are leaking a quart of oil per month there is going to be oil everywhere. If it's clean under there it's not leaking a quart a month. If no leaks it could very well be burning that much oil. Are you seeing exhaust smoke? If it's puffing out smoke as you let off the gas, it indicates valve stem seals (which is cheaper than a re-ring job). Provided of course that these modern cars even have valve stem seals or valves for that matter. lol
Don't use bondo, use jb weld.
