Age,lack of oil,coolant entered oil some how....... while it's running pull spark plug wires one at a time until knock goes away on the cylinder you just pulled the wire on. that will tell you the cylinder with the issue. remove oil pan and replace bearings for crank and rods. It's due-able just time consuming but the cheapest.will it solve your issue?????? Motor is the way to go.
