Spent a full day chasing a phantom knock on a 6.7 Powerstroke

Everyone said it had to be a rod bearing, but it was just a cracked flex plate that you could only see with the transmission dropped. Took me 12 hours to find it. Anyone have a faster way to check for that without pulling the whole unit?

Ever try a borescope through the bell housing inspection hole? Might save you some time next go around. Those cracks hide until they don't.

Been there. Cracked flex plates are sneaky.
