Hey new to the forum here. I just purchased a 63 ford 4000 and was making a loud scratching noise and the starter flew off. Noise went away and ran great. Loaded it up and unloaded, popped clutch and fired right up and ran awesome. Pull the starter out and found it chucked #4 rod out of the block. I have heard these old 4 cylinder diesels used to have issues with #4 and just delete it, remove piston, and push rods and plug oil passage on crank. Only reason I ask is because it ran awesome on 3 cylinders. Or are these worth putting the work in to it to rebuild the motor? I've got roughly $1000 in it
