83 Porsche motor oil leak, were to look?

[Ron1825]

I have a 83, 944 that I am going to replace the radiator with the one out of my 84 or a new one, but while I am under the hood I would like to fix the oil leak. Is there a common place (other than front of engine) on these cars that leaks oil so when I steam clean the motor I will have a place to look and things to check?
