Hello PS enthusiasts!
I have a fairly simple question to ask but don't know if it is necessary or not. I am currently rebuilding my 96 7.3L with 257K miles from a failed piston, #5, which came apart in one of the ring grooves w/o breaking any rings. Luckily, I caught it before it scored the cylinder. I have bored the block 0.020 over, replacing all pistons, rings, main and rod bearings, polished the crankshaft, new seals all around, new reman heads from Ford (old ones had bad carbon pits on the exhaust valves), new oil pump (low pressure), and new injectors from Pensacola Diesel. I am not sure whether I need to follow a break-in procedure for the motor or not? Also, what would be a typical break-in procedure if I do need to follow one?
Any help will be greatly appreciated!
