One additional follow-up for the oil consumption test. My test was done by the dealer (sealed dip stick) every 1K miles for 3 rounds. As for Nissan's exact pass/fail volume, I'll have to get that information and be happy to post it as my service guy owes my some pics of the defective seals and the oil blow-by.
I also used to 'customer service/satisfaction' surveys done by corporate to voice my displeasure and the next day they agreed to pick up two-months payments for my time in the shop.
So far I'm happy with the new engine, although on the next oil change/inspection I'd like a retuning. Oil temps are still in the 220-240 degree range after a 25 mile commute (freeway speeds), but no higher.
