Stock (v2) it kicked out 244 to the wheels, dyno dynamics on shoot out mode. These are raw numbers corrected for temp only.

Considering a $1000 in mods got me (rev-up) to 248, that isnt bad for a base line. I am closer to 275 now..but we will have to see. The dyno read 286on the same dyno but the temp prob was off (it was touching something hot in my engine bay so it adjusted way high). I think its about 265-275. I have a free dyno coming to me for the error. Full synthetic running for 2K miles, not a drop yet. So I guess I should be thankful.

hang in there guys...The BBB has your back.

 

Well, I am headed for the BBB route, as well. Just finished my 2nd round of engine oil consumption tests. The first was some 30k miles ago and yielded less than 1 quart/1000 miles. The most recent series of tests starting at 32,2xx miles have shown that my '05 6MT G35 coupe has consumed some 4 quarts in 2,800 miles. I was told, today, that that rate of oil consumption is normal . . . That's a bunch of BS.

I will be filing a claim with the BBB this evening. Thanks for everyones' input in this thread. You folks are the best.

 

I believe that's correct...

 

If the defective engines are losing oil through bad piston rings, wouldn't it stand to reason that the compression will be low on the bad engines, and part of the reason why the new motors feel stronger is because they're not losing compression?

If you lose 4 quarts in 2800 miles, how are you supposed to make it to the next oil change interval?

 

Makes sense to me. I brought my car in for oil consumption test last week and they did a compression test on my car. My compression levels were 130-145 PSI, depending on cylinder. Nissan said they were supposed to call me after speaking to a techincal adviser to see what Nissan needs to do. A week later, no call back. I'm going to call them today. The service guy said the compression is supposed to be in the 170's PSI range, so low compression = oil consumption = black exhaust pipes = ring issue (probably).

Certainly they can't say 4 quarts in 2800 miles is acceptable no matter what.

 

Just got my 2nd oil consumption test for my OEM engine....

It consumed 3 quarts in 600 miles

 

 

I couldn't believe it myself either...

When the service adviser called me over, I asked him how's it looking.

He said, "You're 3 quarts low on oil"

I was like ----->

 

 

Update folks: Good news, my new oil leak was not the same problem. Bad news, I still had an oil leak with the new engine. Problem was a defective oil cooler, and improperly installed "inner" oil pan. The oil consumption test only showed less than a 1/4 of a quart of oil consumed. Most of that was due to the oil leak. I'm actually OK with this b/c as you guys know, the original oil problem showed no signs of leakage (well at least mine did). I checked the oil after I got it back from the dealer, and it's right at the H level. I'll keep monotoring the oil level, and I'll be taking my Z back at 1000 miles for another consumption test.

 

If nissan doesn't buy back my Z, I might just trade it in...I'm really getting tired of these different problems/arguing back and forth.

 

This was the V2?

 

Yep

 

hmm, sounds like good news....keep us posted as you rack up the miles.


...As far as my OEM motor, they want me to drop it off on Monday for compression tests. I hope they don't fock anything up

 

Just finished my oil consumption tests. V2 on order. Dealer even said that this will be a temporary band-aid until the new motor w/ updated piston rings arrive. My OEM motor burned through 2 quarts in just 700 miles. Even the dealerships now know that the V2 is no different. Im starting OC tests on the v2 as soon as the break-in is over.

 

How does the buy-back process work? I pretty much stole my 2005 35th anniversary from a Mercedes Dealer. They sold it to me for 24,995 with only 6000 miles completely flawless. It is still flawless with 20,000 miles now. So would they just pay it off or give me market value?

 

So your dealer claims the V2 does not solve the problem? There are quite a few here, including me, who are showing little to no oil loss with the V2. Granted, in my case, it is too early mileage wise to declare a victory, but where do they get their info/knowledge that the V2 is just a temporary fix?

It is a popular dealer here in so cal. They have done many swaps for OC w/ little success. I as well am confident the "hand-built" engine wont do anything. My car was not an oil consumer until about 12k miles. Im glad to hear your car is not consuming oil but I am less than optimistic

 

If they don't comply, go BBB...that'll get them talking

 

It is not consuming now, but it is way to early to tell, only 2500 miles on the V2. For the sake of argument, assuming you are correct (not doubting your source info, just questioning the validity), you mentioned your dealer said something about a future "permanent fix" . Does this dealer feel another engine will be forthcoming, a V3 for lack of a better name, or some other fix? Please share what they have told you please. Thanks!
