Nissan has a history of oil consumption on these VQ engines, it's a fully legit concern IMO. If there was no track record, maybe not. It's not conjecture, and people with this issue should complain about it. If people do not complain, nothing ever gets fixed, how else would nissan know there's an issue to begin with? NO engine should consume that much oil during it's normal operation short of a rotary perhaps. Break in or no break in. The end.

However, now that a TSB has been issued by Nissan, there's no harm in owners waiting until the 10K or 20K mile point to ensure that the oil consumption issue hasn't taken care of itself. Most owners will have put 20K miles on their cars well within the 4 year/50K mile powertrain warranty period. IMHO it'd be foolish to pursue a short/long block replacement too early in the engine's lifecycle if the problem would've taken care of itself in time. Besides, there's some anecdotal evidence from folks on the this forum that early oil consumption in the VQ37VHR settles down after 10K miles or so.

I think it's prudent to wait. That's what I plan to do. Now that the TSB's out, there's no reason not to.

It doesn't like your PDF. Is this just a ordinary PDF?

Edit: It appears as though there is some kind of file security (FileOpen) on this file.

Yep, there is security as I caught it at the firewall...when it hit it.

...and hopefully my dealer will have swapped 50 long blocks before they ever attempt mine.

From what I understand, dealers are now instructed to do Short Blocks. I never asked what it would take for the dealers to do long blocks.

Far greater chance of an assembly screw up or contamination with a short block swap. Be afraid. The Nissan techs are not engine builders and may not follow all the industry assembly procedures. If your engine fails demand a long block.

i take great offense to this statement...i am a nissan tech, tomorrow i will be performing the oil consumption bulletin on an o6 350z... i follow all guidelines and torque specs that nissan has provided in the service manual... as for nissan and the short block instead of a long block.. the bulletin specifically states if the vehicle fails oil consumption test it gets a short block and full gasket set, and honestly i think the only way to get a long block would be to complain to nissan directly, the dealer really doesn't have any say, because there is a specific billetin for the problem...
WarmAndSCSI sorry for the delay with getting the bulletin pdf uploaded.. was swamped today with two pathy timing chain tensioners... lol to add to another long day 350z short block lol i love my job...

It wasn't meant to be offensive, just a statement. I'm sure you are a very good tech but for engine assembly I would would prefer an engine builder, i.e. someone that does it day in and day out, not once a month or more.
