Failed oil consumption test

Well, to properly check every single camshaft/eccentric shaft journal, cap, etc for roundness and wear would take some serious labor. The OP should at least force them to do a thorough inspection of every component in the engine. And that plus proper reassembly (and associated risk) is probably just as expensive due to labor costs as getting a new long block or whole crate engine put in.

Nissan has to reimburse the dealer for labor and parts costs, so they'll probably go with the option least likely to produce a repeat incident. Which that is, who knows.

If it were me, I'd replace the shortblock and be OK with it, but I don't even trust the dealer to change my oil, yet alone the lower end of my motor. That's my concern more so than whether the replacement lower end fixes the issue.
