i believe the ending of A means its not v2...and that its a v1, as the only v2s we know of are for the G and Z and they in in Z or 6....this was discussed earlier...like a few pages before you (zeeforce joined this thread, fyi =) )

Part# 10102-AC7MA is the part # of the original engine. Any dealer still installing that is wasting his and his customer's time because it will not solve the problem.
Part# 10102-AC7MZ is the V2. I'm 100% sure about this because I was at my new dealer 10 days ago and specifically asked for the original engine part number. I then asked him to look up 10102-AC7MZ (which I obtained from this thread) and when he did there was no part description but a special instruction to call a designated person at Nissan Canada.
Last Monday my dealer called and said they had a new engine for me so I went over to look at it and to my pleasant surprise it was the 10102-AC7MZ which was clearly labeled all over the box.
BTW I'd been getting jerked around for the last year about this problem but as soon as I contacted the Better Business Bureau (I didn't even know they were also in Canada) the situation was resolved in 6 days therefore I strongly suggest everyone everyone go the BBB route.
My install is on Oct. 1 and I will post the results ASAP.

I took it to Nissan and they said my oil filter was seeping oil (I had changed the oil myself before) so they changed my oil with dino 5W30. After 1000 miles, the oil was on H. I have been checking myself and now after ~3000 more miles (4000 total), it is at low.
I am taking the car in tomorrow for oil consumption again, and am bringing synthetic oil for them to use for the oil change, as it seems to exasperate the problem for most people.
I believe my oil filter before was not leaking because I had painted my garage floor before this, and there was no oil where I park my 350Z. My tail pipes are black and have been ever since I paid attention to this.
I guess the question is, will they take 1 quart in 3000 miles with dino oil seriously at all, or say it is normal. I believe it is not acceptable for a highway cruiser, which I do not race. What is the minimum burning that Nissan replaced the engine?
Any suggestions would be greatly appreciated. Thanks.
PS Despite my sig below, the only mod I made to this car was to install leather seats from another 350Z. Everything else is stock.

Compression is rated at 10.3 to 1. I am not sure what that means compared to the test results, but maybe it is 10.3 atmospheres or bars. If so, that is ~150 PSI. Cylinder 5 is 130, which seems low compared to the others, so maybe this is the issue.
Nissan tech will report it to an adviser tomorrow and let me know the results. My car is an 06 with 17K miles.
If anybody knows more what these numbers mean, and if they are OK, I would appreciate it.
Nismospeed4life, thanks for the info on oil consumption.

Thanks for the confirmation on the part #, I can sleep tonight.
Good luck with the install and let us know so we can add you to the list of testing.

Yeh, good info on the oil, I am still bouncing back and forth between the oil and this thread. Lots of reading.

im looking @ buying a 06 350 if i buy it and it has this problem will the dealer fix it.....its only got 11k on it
thanks

--------What i know about motors that is ok.. you can go +- 10 psi
hope this helps

Just some info on revup v1.
My V1 has about 9600 miles on it currently. I broke it in according to the manual. In addition - I changed the oil @ the first 100 miles, then again @ 500, then again @ 1500, and now at 3000 mile intervals.
I have been watching the oil consumption closely since I got it. My observations are as follows:
* Using 5w/30 Castol GTX it consumed @ 1/3 - 1/2 qt per 1000 miles.
* Using 10w/30 Castol GTX it consumed @ 1/4 - 1/3 qt per 1000 miles.
My consumption hasn't really gotten better or worse (within each weight of oil).
* I am switching to Castrol GTX dino 10w/40 this weekend to see how my revup v1 likes that. I'm hoping a heavier weight oil will slow the consumption down even more... But it's still BS that we'd have to do that.
(I use Castrol GTX dino oil, because it is very highly rated in the Oil Sticky for our VQ engines)
Aside from oil consumption; I was getting a lot of ping when the engine was under load from 2000 - 3000 rpm and ambient temps were above 90F. I am UTEC tuned with full bolt-ons and the interesting thing is that my UTEC never picked this ping up in my knock logs (and I have the knock parameters set very sensitve), but I could still hear it.
Ambient temps play a big role in how these engines run. So I kicked the timing back a degree and added a little more fuel in that rpm/ load range. Ping is almost entirely gone now.
I have my tune 'global parameters' set to advance timing and subtract fuel when ambients are below 90F. Still no ping.
I have a feeling an oil cooler or after market radiator would take care of the 90F/Ping problem. Then I wouldn't have to 'de-tune' @ 2000-3000 rpm when the temps are above 90F.
I would normally be concerned and upset with the BS of the revups using this much oil (because you know the compression is lower as a result of the blowby)... But I was planning to do head work / cams / stroker kit in a few months anyway... So I guess I won't sweat it. But if I had planned to keep the car stock, I'd be p1ssed.
Anyway, just thought I'd share for what it's worth...

Compression test readings should be +/- 10%. Therefore 145 and 130 seem close. However, Im not sure what the readings should be, but I believe they have been posted here a page or two back. I believe it should be closer to 150 or more. Therefore the 130 and 135 readings likely represent bad results and you should fight for a new engine as the rings and or chambers are likely damaged.

Is the car you're looking at an automatic or manual? If it is an auto, you don't have a rev-up motor, and this issue is prevalent on the rev-up only.
I'm not sold on the 130/137 being OK, as it is 20/13 PSI below 150 PSI. 130 PSI is approx 8.5 to 1 compression. That can't be good for sure. The fact is they did a compression test on the first "verified" 1 quart burning on the motor. I suspect it was done because of my nice black tailpipes, which is indicative of ring issues.

Just got back from the Infiniti dealership, they said that my 5AT consumed 2 quarts with the first 1000 mile test. They want me to go back in another 1000 miles. I'm not sure that the point of another 1000 mile test is for.

What's V2?
I've been trying to figure out what V2 engine is, and I still haven't got it figured out. Guess I'm slow...
Can someone explain what V2 enigine is, how they are different from the older one (V1?), and what 350z models/year came with the engine?

I just wanted to thank everyone here. I've done 2 Consumption test already and Nissan Corp. still hasn't done anything. I talked to Corp. Nissan Rep. and they just said to wait for the fix. Finally I just had enough of it and went to the BBB and after a week they have already contacted Nissan Corp. and they are replacing my engine + 100,000 extended warranty.
As of now I'm losing 1qt every 1,000 miles. They have placed an order for an engine & I specifically requested the V2.
