You're not going to get an answer with any validity. Nissan may just be swapping the same engine design back in hoping lightning doesn't strike twice.

Yes!!!!!! I have seen it. This TSB is actually for the 370Z.

Then someone please post the link where I can print out the TSB that has a Nissan header at the top and an internal TSB reference number that my dealership can punch into their computer for lookup.

Not that this matters much, but Nissan has a history of excessive oil consumption even with the V-8's. I bought a new 2002 Infiniti Q45 and it sucked oil like crazy. Seems it turned out to be a common complaint. They finally replaced the engine at 28,000 miles and there was considerable improvement. But as mentioned by others, that is not a real great experience either...it took several trips to get everything sorted out. Fortunately, my 370Z does not seem to have a major oil issue. I've got the fingers crossed.

You know...tho......as long as there are no other serious problems associated with the excessive oil consumption.........I am not going to worry about it.........Just keep the oil level topped off.......an so what........it dosent really cost that much to buy oil.....

cab83_750 · 10-19-2010, 12:01 AM

Do you have smog-check in TN? We are just afraid that oil might be clogging the cats and we would fail the test! I wouldn't even tell you how much 2 cats cost!!!! YIKES!

About $300 on this site in the 'parts for sale' section. Frankly, I'd rather replace cats every 20k miles and a quart of oil every 1k than go through an engine swap at a Nissan dealer. The consumption would have to be REALLY excessive to make me go with an engine swap.

I have more concern for those folks who see every little thing as a problem. Its this kind of reaction that starts to cause the car to come under relentless and unnecessary scrutiny for absolutely no reason...and once this kind of over reactive :BS: starts getting into the car magazine reviews the entire car starts to drop unnecessarily in its value quickly all because of supposition and conjecture.

So how about showing some patience and restraint and quit posting your needless concerns until there is a definite and provable problem identified and a root cause of a real failure instead of all this dust some of you folks keep kicking up about nothing.

if everyone waited, then nobody in the past with the older VQ motors would have complained and a bulletin more than likely would not have been made up. 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.

Glazed cylinder walls, increased emissions, burned out catalytic converters, reduced power, the list goes on. (that's assuming the problem lies in the piston ring sealing/cylinder wall finish)

It's not acceptable at all.

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.
