This causes oil to blow by the rings and into the combustion chamber hence blowby and why you see soot in the tail pipes.

The lower plenum collector is different compared to the non revup, hence thats where the hp comes from and drop in tq as well compared to the non revup. Valve duration timing is another one.

There was someting like 3 times the loss of oil in millimeters on the dip when driving hard.
I can't do this b/c my second V2 is not complely broke in but I might test the hypothisis since it is repeatable.

I feel it's a part quality issue still in addition. Have pictures of an oem revup with only 1600mi on it and had serious OC issues. The piston ring landings were discovered broken during disassembly. Will have to re-down load pictures from my source, being they are small and detail is hard to see, but in a nutshell...I conclude that VQ failure to be due to a defective internal part.

I agree with what you're saying. I'm reiterating what this annonymous Nissan Tech who refused to ome forward on the other site for fear of his job. He said it is a heat distribution problem in cylinder walls which can be linked to the different heads in the rev up. I think he said these heads help boost the hp although there are as u pointed out other changed parts that boost hp.
They might as well give us all '07s since they're wasting money on these multiple V2s

But yea, oil consumption seems to happen when actually reving the engine at its desired power band lol. Im glad my issues with oil have been solved or else i really wouldve considered a nismo Z.

^ Yes agree about ppl stating breaking news and then only to not respond when confirmation is asked or follow-up. Had a member on Driver state about Infiniti IS working on a V3...blah blah...I asked for more details, never has and hasn't to date updated. I do understand the confidentiality thing as I have similar info I've agreed not to disclose publicly by request of a professional scientist for my issue with my VQ.
Here's those pictures of a OEM revup with 1600mi torn down. Owner said forget Nissan and did non-Nissan build. He reported 8 months later, no OC issues.
Food for thought. Wish we could see a V2 torn down.
^ Aftermarket on left for build; oem on right at 1600 miles
All the landings were cracked or broken.

ok guys so i have 800 miles on first engine replace the v2 engine, checked the oild today i'm almost down 1/2 on the dipstick. by 1,000 i will be at half way on the dipstick. v2 for me = failure.
call the dealer told them what was happening they told me to wait let the engine break in for 3-5 thousand miles and that if i wanted to bring the car in they would put more oil in.
dont know what to do now. this sucks man, wanted to trade in for an 08 but i will loss money

My 06 G35 is consuming oil, and it's clearly worse when I rev the car more.

surrendered my vehicle today. They had a third party do the inspection. So could have parted out the brembos! The guy had no clue. Anyone with questions feel free to email me at:

Nissan needs to own up to this as a failure - soon - or there will continue to be unhappy campers suing them worldwide.

I took my car in today to a Nissan dealer to get the results on my 1-k oil consumption test. The results show that my engine is not burning oil. I was disappointed because I thought for sure I had the OC problem. For those of you who are not familiar with my case, one morning my car had an outrageously loud knocking noise (it sounded almost like a blown engine). Since it wasn't drivable I had it towed to the closest dealer. They said they "fixed" it just by adding oil. They put me then on 1-k OC test.
What pissed me off now is they're saying that my engine is fine, it's not burning oil (he dismissed the fact that I had my car towed at my first visit because the ****ing engine was knocking hard). Now, I should be patient and wait for the crappy engine to break again. And I know driving it really "hard" guarantees oil burning.
I'm building my case now. I guess multiple visits to the dealer will work in my favor.

NNA accepted buyback of my car at the sales price. No lawyer in the middle. Here's how the procedure works.
Call NNA and ask for buyback due to the V2 or V1 consumes verified by dealer OC test. They have 30 days to call you back regarding the offer. Just that easy. But get this - when they call you back the first offer they ask you is to accept $4,500 and sign an agreement you won't ask Nissan to buyback. Once I declined this offer he immediately offered complete buyback. He makes it sound as if Nissans response to your buyback request is only to offer the $4,500. Then once you decline it they put another offer up to buy it back. They know you have them by law and they have to be responsive within the 30 days! but they manupulate you in deceptive way to try and get you to think their only offer is $4,500. Doesn't suprise me - do they think we are stupid in Japan or what. the arrogance of corporate Nissan!

ZPimp,
Congratulations! Got a couple of questions.
1. Did you buy the car new or used?
2. Did they charge you anything for the miles you used the car? It sounds like they didn't. According to the California Lemon Law, they can charge you for the miles before you first report the OC issue to them as a fraction of 120000 miles. If they aren't charging for this, that is a big plus!
I don't want to use the Nissan approved arbitration because it is much worse than the California Lemon Law. If NNA is at least using the lemon law rules, then that is better. If they are offering full purchase price back, that is BEST.
Nissan Arbitration = price paid - (miles @arbitration/100000 miles)*price paid
California Lemon Law = price paid - (miles@first time issue reported/120000 miles)*price paid
One thing I can guarantee is that a car isn't worth $0 at 100000 miles
The more I learn, the more it appears Nissan knows the rev-up V1 and V2 are a gamble (at best) not to OC.

Does anyone know if this Buy Back procedure works for Canadians?
Honestly I'm happy with the $4500. That will pay for m engine build that they can't do.
But I can't even get that out of them.

. but hey its burning oils all ready. they said along with what the dealer said to wait till the engine break in.how many engines did you have replaced before you called them to get a buy back also how many miles did you have when you call them?
