    oil leak from back of motor

    hi i have a 79 425 all stock thats leaking oil out the back of the motor. i thought rear main but i have the dust shield on and i get just as much oil drpping off the starter so im thinking its comming from up higher. im replacing the original valve cover gaskets as i wright this so maybe that is it but im just wondering if theres anything back there that could also leak. thanks

    Yes, the oil pressure switch is located on the block in the middle over the bell housing flange. They usually have 3 terminals in those years. One to complete ground for the idiot lamp and 2 for power to the electric choke.
    You need a specialty socket to unscrew the thing if it is the problem.
