cavalier leaking oil real bad when running

Hi, i have a 1996 cavalier 2.2 liter. The car leaks oil real bad when it is running, also the oil level is way overfilled. My question is, do you guys think its leaking oil that bad because it is overfilled, if not what else could it be. Tommorow im gonna drain the oil and put it back to the normal level. Im also going to the junk yard tommorow, so any advice before then i would appreciate. Thanks

Try to determine where it is leaking oil. Look at the front and rear main seal.
Look at the oil pressure sending unit is it leaking. Is it leaking around the head?
Tell us what is leaking and we can help you.
