360 LA getting oil in #3 cylinder.
Sounds like you have a plan, check out a few things and do what you need to do. When you have time.
Might have got hot and blew a weak spot in a head gasket?
So yeah take care of family, car is gonna be there. And Oh yes the mopars are good investments, they hold their value. A few parts and learning and tinkering, good to go.
Hard to say who had been in that engine before you got it. Improper torque on head gaskets, not enough torque. Maybe they cleaned up the deck (and or head) with a wire wheel on a drill and unknowingly cut a groove from that oil feed to the cylinder, then put on some cheep head gasket that leaks.
You never know with these cars having been through many hands.
Good Luck
