ballooned oil filter

ok so I just picked up a 66 dart with a 273 auto column shift, it's been sitting since 1987. so I dumped the oil, new filter, hooked a hose to fuel pump and went for broke and see if it would start, low and behold it started. ran ok for sitting so long. anyway the oil filter ballooned up and leaks at the oil filter gasket. I see one of 2 things. 1 the 90 degree adapter bolt was over tightened pinched oils supply holes in the bolt and slowed oil flow to the point it backs up, 2 the crank bearing that is associated with oil supply spun and blocked off oil supply. anybody ever have a ballooned oil filter before.
