That sounds like standard big co standard operating procedure..
Honestly I was surprised to see even a part number change. I thought for sure it would have been a revision only change. I'm in product development in transportation and it's totally normally to see a rev only change for an improvement/fix. In most instances customers do not WANT a new part number as it makes purchasing a hassle. Given that the part numbers have changed at least once, maybe twice, and that Infiniti is replacing them almost no questions asked, it really points to what should have been a full on recall. The bean counters said: A)not safety related + B) probability of taking out other equipment like the motor or catching the car on fire is low enough + C) cost of doing replacements on a case my case basis <= cost of a full recall. Hence only a TSB. As bad as it is, they're not stupid enough to change the part number and use the exact same turbo as that can be criminal as it's willfull intent to defraud.@Ddnspider has anyone actually been able to confirm a change to the turbo outside of a part number change?
While I'll agree that part number changes often signify a revision, they often change due to batches as well. Those two could happen at the same time of course but I've never seen anything that suggests actual improvements were made. I would hate to think that the new turbos are different when they're not, and the reason we don't see failures on newer turbos is because, well, they're just new.
I've looked on this site and not found anything. If my google-fu has failed me then that's fine. Do you have any concrete evidence? Hell, I think if take anyone's word for it as long as they've physically compared the old vs new turbskis.
It was most likely already burning oil but the cats were masking it. I imagine this is the case considering they did full downpipes, nothing in the exhaust to burn up/catch the oil.
