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.

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.

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...

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!

So if your car was built before those last 6 numbers at the end it could be an effected engine??? Cause if so I'm 503734 LOL... But knock on wood I have not had to add alot of oil to the car in between changes and the engine is nice and quiet.

gorillanismo · 10-02-2010, 07:15 PM

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

SoCal 370Z · 10-03-2010, 12:53 PM

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

This is for real.

Vehicle VIN/DATE:
JN1AZ4FH(*)AM303670/05-APR-2010
JN1AZ4EH(*)AM503778/05-APR-2010

Some guidelines on "NO GOOD" engines:

Miles mm from H (dipstick)
1001-1500 >=10mm
1501-2000 >=13
2001-2500 >=16
2501-3000 >=19
3001-3500 >=22

OK. Now, let the self-OC-tests begin.

Info above is what I have. Right, wrong, or indifferent, use it or ignore it. I am not claiming accuracy nor provide guarantees, recommendations, etc. Use at your own risk. Use GOOGLE or check with your dealer!!!!!

ZForce · 10-03-2010, 02:09 PM

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.

gorillanismo · 10-04-2010, 11:27 AM

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...?

PapoZalsa · 10-11-2010, 03:26 PM

I just took my car to the dealer today because with less than 2700 miles since the last oil change the car consumed 1 qt of oil.

Their recomendation was to change the oil every 3 months... Ester Oil.

They say that my car is going on the list of Oil Consumption Problem Program so they can monitor the issue :dunno:.
