Oil Leak

I HAVE A 1985 F150 351W, IT LEAKS OIL WHEN RUNNING ARE THERE ANY COMMON PLACES FOR THESE TOO LEAK?/ IT'S CLEAN EXT CAB-- NO SENSE GETTING A NEWER VERSION, ALSO ANY PERFORMANCE UPGRADES TO HELP // 110k 4BBL MOTOR/3.55 REAR THANKS

4x4 cam, dual exhaust with an x-pipe. As for oil, check the valve cover gaskets and the rear seal. Might want to get a edelbrock 650 carb.

If you live in the rust belt check your oil pan for rust through. Fords are good for this. My 93 is on its way. Rear spring shackles also rusted through on mine!
