Engine failure after oil change

I had a 318 that had a leak from a cracked oil filter mount. It would only leak while the engine was running so no huge oil spots on the driveway. Motor finnally blew up from frequent low oil conditions. Broken crankshaft and 2 broken main caps and I drove it home like that about a 15 mile drive. Sounded like a jack hammer. I threw in a new crank bearings and a couple of new main caps and it still had the low oil problems. Had to get under the car with the motor running to find the leak from the filter mount.
