The other issue which is much more serious and probably the main cause is poor quality rings or improperly placed rings. One unverified theory is that the rings are of poor quality and come loose after a certain amount of driving. Another possibility is that the expansion gaps in the rings are not offset like they should be, but more or less lined up. TILLEYS99 has seen this first hand on a VQ35 that he pulled apart, so we know its a possibility. This is where my knowledge ends, but I guess its possible that its because the rings came loose that they ended up lined up?

To add to your thoughts, I understand it depends on the way people maintain their cars and their driving habits.
What i will say is that THIS IS A KNOWN ISSUE BY NISSAN which is why they don't really hesitate as much when a LONG BLOCK is needed to be replaced by the customer.
Having this knowledge, I doubt I would ever buy another maxima used in teh 2k2/2k3/2k4 years (i think 2k5 and up - problem was corected) because your warranty is almost up and replacing a motor isnt the cheapest thing.
The funny thing is my dad's Benz E320 needed a new motor. The dealer claimed 1quart every such and such mileage to burn was okay. But on a benz the service intervals are in excess of 10,000miles (about 15-20,000 kms between oil changes). By aobut 8000kms, there was NO OIL IN THE ENGINE, so how can they expect that level of burning oil was okay. Long story short, motor was replaced under warranty..

So is nissan going to recall any or all of these motors? Toyota had a similar problem in the mid 90s on a couple models with faulty head gaskets. They basically rebuilt 10's of thousands of motors. Looks like Nissan could be in the same boat here?

Sup well i have a 2k2 A33 6SPD wit 55k miles.... its running really strong.... actually i dynoed it not to along ago and its did 273hp stock!!!!! and torque was i tink 256.... damn i'm lucky all i get is a high pitches noise at slow speeds but it goes away when i engage the clutch//

No such thing as a 273hp STOCK VQ35DE (assuming this is at the wheels).
Its a virtual impossibility that your car is a factory freak with 65hp over the regular dynos of 2k2/2k3 6speeds of 205hpish.

Couple things that come to mind when reading...
1qt every 3k is considered normal by most manufacturers of high performance motors. The LS1, LS6, LS2 all burn about a quart every 3k miles. The LT1 burns roughly 1/4 to 1/2 quart every 5k miles...The Vettes, Fbodies, Mustangs and lots of other vehicles have this.

I still wonder if this is due maybe to a combination of bad parts (ie piston rings) and poor break in procedure.

probly, and the 15% on here i think would be a little off because the people on here are more likely to rev their engine up, race and do anything else that gives the motor crap. i think most grannys wont be experiencing oil burn and would take that 15% down quite a bit.

With the exception of newer 'Stangs with the 4.6L SOHC, most of these cars have pushrod motors built on technology from the 1960s. The reality is that they don't posess the refinement and build quality that many newer engines do, let alone the world-leading VQ. While those engines are solid designs and good for a lot of power, they do not age as well, which is only further accelerated by the fact that many of their owners beat the hell out of them.
1)Headlight motor
2)Water pump
3)Wheel Speed Sensor
4)Pinion seal
Other than routine stuff thats all I've done. They age very well if they're treated right. My dad was a cop and put 155k miles on his built LT1 car. Went through 3 transmissions but the motor was still running great even when he died. LT1's and LS1's are very reliable IF they're maintained. The problem you see with F bodies isn't the motors, but the owners. I know several people that have owned them that didn't change the oil/filters at approrpriate intervals. The results of course are spun bearings and damaged internal components.

true dat. i know people with LS1's and theyre great engines. run good, get good mileage and but out tons of power. however, the volumetric efficiency with our vq's is better than the LS1's. in other words, we get more power/liter NA than they do.

I have an 03 with 43K miles on it and no noticeable oil consumption at this time. I bought it with 25K on it from a gal in Wisconsin, so I doubt it has ever been abused. I rarely push it to the limit and generally keep it under 3k RPMs, so I would say my car has been babied. Only time will tell if the problems are going to develope later in it's life.
I do have some timing chain rattle during the first startup in the morning, most days, but it only lasts a second. Doesn't happen during normal operation or even after it sits for a couple of hours. I have thought about taking it to Nissan under the powertrain warranty to have it repaired, but I am concerned that even if they did the repair, it may result in additional problems later. My 00 Max did the same thing and I ran it up over 130K before I sold it. It never failed and didn't burn any oil.

I have to wonder, why is it that some have a huge problem with this and others (the majority) like myself have no significant oil burning issues? If it were a honing or ring problem wouldn't we see it on the majority of motors?
