There are 3 different versions / combinations of the N55.

Vehicle came to us with a rod knock.
During removal and inspection, found an "early version" N55 that was currently present instead. During tear down confirmed rod bearing failure.
Fun Fact: An attempt was made previously by installing another new set of rod bearings as seen in the pictures.
