(now) been flooring it to 7500 rpm every time I drive it. Test drove it from the dealership from mile 20-26, and floored it a lot then...hopefully that didn't do anything...or anyone who drove it before the 20 mile mark.

Sounds like you adhered to the Nissan recommendations to the 'T'.....NOT.

What Nissan recommends is simply in place so somebody doesn't A) smoke the **** out of a non-broken-in organic clutch in the first 500 miles or B) seize a camshaft or other engine component that actually DOES need a short break-in.

CYA for Nissan. That's all it is.

I'm not sure this is true. I checked my oil level again today and, after the car sat for about 5 hours, it was at about 13-14mm below H (3400 miles, no oil change yet). I added exactly one quart and that brought the oil level EXACTLY to the H dot.

what happened to nissan?? Im a fanboy of Nissan but this problem started in 05, 5 years later we have same problem with high rev engines???

Nissan needs a engineering fusion with Mercedes for a V6 VVEL Twin Turbo Direct Injection engine...

a friend who just went through a short block replacement showed me the paperwork on ntb10-090 dated july 30,2010. it is the the service bulletin for 09 to 10 370z for cars with vin built before april 5, 201 jn1az4fh(*)am303670 and jn1az4eh(*)am503778 ... it is pretty much the same as the infiniti tsb...

There's nothing wrong with the design of the VHR, if engines are legitimately burning oil regardless of break-in procedure, the fault lies in quality control. Maybe they forgot to plateau hone some of the cylinders! Whoops!

Who knows? Nissan of course will never admit what went wrong, but I'd like to get a hold of a failed short block to see what the cylinder walls show.

Man but we have 5 years with the same problem...
that's a big problem...

We need to hear from some tribologist' or at least some UOA's analyzed by triboligists and not just the data from labs like BlackStone.

True NNA will never admit failure or quality control on a TSB. A recall is a different story. My dealer did not even have the authority to tear it down. All of the dealers were instructed by NNA to ship the bad long blocks (untouched) back to Nissan in Tenn for inspection. The bro had one of the first replacement engines, when they were still being hand built in Japan.

Note: I am referring to the 06 RevUp long block.

Has anyone been able to confirm if there is a TSB for the 370Z and get hold of the TSB?

If this is true I think a new thread should be opened up by a 370 owner and by someone that is going to be able to take the responsibility to own it and update the first post on an ongoing basis. Because it will get loooong!

It's real, but I can find no detailed specifics, yet.

Edit: My bad, looks like NHTSA has a TSB search engine that is not by claim and INDEED they do list the TSB as SoCal 370Z provided above.

I would like to see a scanned copy of the service order on the short block replaced with the TSB listed.

I just checked with my resource for the official TSB and came up empty. It does not mean it's not out there and valid just that NNA has not posted it yet to my resource.

J. Dub 10-04-2010 11:05 AM

For all those, like me, that had a 350z.... Looks like we bought the same problems we use to have. Can't wait for the 400z. Cause then I'll get to AGAIN consume oil along w/ money in my wallet via purchasing 1 qt top offs.

I think Nissan boarded the failicopter back in 2005 and hasn't gotten off the ride yet.

this problem will be fixed in the 2011 model or will have to wait until Nissan design a new engine??
or is that Nissan have quality control fails each year in the VHR lines...?
