I wouldn't have the buddies start tearing the motor apart. There is a lemon law in OH, regardless of the "as is" that you said earlier. You bought it from a dealer, take it back. If you are dead set on looking at it, you can find an oil leak by using atheletes foot powder in the spray can. External leak only of course. Start motor, spray with the foot powder, if it turns purple then that's where your leak is
