It sounds like you did a compression test on yours. How were the results?

gbauer, you get a response out of nissan after that email? i had a similar problem except mine sounded like squeeking, checked the oil and it was low (i recently changed over to synthetic as well) topped it off and things seem to be better...this thread is starting to scare me :-\

Its scaring the hell out of me, because i notice my 03 seems to burn a little oil. my 02 would never lose a drop of oil. now i just changed my oil and a week later it was a little low WTF

just got my car back from regal nissan today - good news and bad news
good news is my engine is not destroyed (supposedly)
bad news is there was ONE freakin quart of oil in the engine
i use mobil1 5w-30 and changed it myself about 4k miles ago/2 months (i was due for a change)
so my oil is fresh and full and the noise is gone... but i am pissed that my engine burned over 3 quarts of oil in such a short time!
WTF???????

Dammit, I also noticed a low rattle at about 2k rpm, but I attributed it to putting regular gas in my car and getting an engine knock. Been running super again for 2 tanks now and I thought I heard the rattle again the other day.
Is this mainly for 6 spd's or auto's as well. I'll have to listen more carefully now to see if I can hear it again.

I would like to contribute as well..
I have the same sounds.
Been reported to my dealer since April 2005. Apparently my dealer has a 2k4 in with the same problem.. Finally the 2k4's got its engine approved for replacement. My service manager told me, mine should be coming but the engine replacement approval from NNA takes FOREVER!!!!... The 2k4 approval took nearly 6 months or so.
I think my oil burning is WAY WORSE THAN ALL YOU GUYS!!.. In 600kms, i was able to burn from FULL mark on the dip to LOW mark. That is 1 weeks worth of driving. I am tired of NISSAN, and the VQ35DE is a piece of $hit. This issue isnt just wiht hte maxima. I scanned the g35driver.com board as well as the 350z and GUESS WHAT!! They have the same damn issues too with excessive oil loss.
This is my 3rd nissan maxima. 1999 max se, 2002 max se, and finally my 2003 max se. My mom drives the 99 and even with 180K the VQ30 in her car is NO PROBLEMS!! still runs stronger than mine. My 2k2 was smashed up. And my 2k3 with only 77,000kms is already exhibiting the brinks of serious engine failure. I fill up a liter ever 1 to 1.5 weeks. My fuel economy is shot to $hit especially with the expensive gas these days. And i am FREAKIN PISSED OFF with nissan's overall reliability. Never will i buy another nissan again. I thought my dad's mercedes was bad, well at least his engine lasted till 120,000kms before needing replacement.
But then again, what car out htere is really all that reliable anyways? Stupid VQ35's.. I like my car but these issues is not minor. If i decide never ot add oil over the next few weeks, I am sure my motor will be dead. Perhaps I will choose this approach, cuz i am sick and tired of waiting for those guys at NNA to do something.
I mean they told my dealer to mess around with my PCV valve and some gaskets.. PROBLEM STILL REMAINS. If i grenade my motor with no oil, maybe i can let them keep my crapima and have ASP pay for my RENTAL CAR until they replace it.. I am sick of this $hit.
BTW.. its not my dealers fault. they have been amazing to me, and half the toronto maxima club goes to this one dealer!! Kudo's for their hard work.

Hey guys, I have the exact same problem. I have about 56k miles on my 2k2. I took my car to the dealership last week. They said that it was due to low oil pressure b/c the oil filter that was on it (FRAM) did not have a control valve that Nissan filter's have. He said this was causing the low oil pressure. I've been driving it a couple of days now and have still noticed the rattling. I'm going to be taking it back shortly.

Folks -
I have an '02 and the good news is that it is not yet burning any oil. I have been running Mobil One since my first oil change around 500 miles. I do have some ideas as to what is happening here though:
1. Is it possible that the two pre-cats over-heated due to very spirited driving and/or a rich fuel mixture and little pieces of the cat got sucked into the engine? David B. was telling me that this is a big issue on 2.5 Alti's and that he's already seen a couple of Max's with the issue. Of note, David's comment was that both engines use the same pre-cats and that they are located very close to the exhaust valves. I think the compression test would be a good indicator for this.
If it turns out this is the problem then it would seem that the real culprit is the ECM program and/or faulty sensors.
Has everyone with the problem had the recalls for the cam/crank position sensors and the MAF/ECM code performed?
2. Is it possible that the main cat got clogged up? I think I remember seeing someone (was it GBAUER?) who had this problem. Replacing the rear cat resolved a number of performance issues he was having including excessive oil consumption.
If we do determine that indeed the problem is with the cats, are there cheap replacements available aftermarket?
Just food for thought.

hi, could you expand on why a clogged cat would cause oil consumption? i think i am issing something here...

absolutely, you can tell many things about the way a car is running with a vacuum gauge...
basically, a no load, raised RPM (2500ish) will provide more flow than the cat can deal with... if the engine cant push the gas out, it cant bring a gas in, which causes a decrease in vacuum.
normally, holding at 2500 would give 18-22" or so... maybe a little lower. a restricted exhaust that figure will drop slowly, usually down to below 10", depending on how bad it is...

I would not have any use for the boost option but the gauge has both options and is not separate.

After having my shortblock replaced about 1 1/2 months ago due to oil burning issue. My car started to make a rattling noise under decceleration around 2-2.5k. I took the car in last friday morning, after calling on friday afternoon, saturday afternoon and monday and tuesday, today I finally got a concrete answer.
They ordered parts for my car, apparently some type of gasket or two. Also, I've been told that the guy who moves the cars hit a jack or something and messed up my door.
The service advisor told me the part will be on monday or so, and car should be ready from bodyshop on wednesday. I am going there tomorrow morning to switch rentals, so I'll definitely check it out and maybe take some pictures.
About the bodyshop situation:
What should I ask? I already told the service advisor about a small nick i have in my rear fender and she said it would be no problem to fix that as well. I know they don't have their own bodyshop too, which just might be better than if they did.
I'm tired of not having my car already.

Spoke to two dealers and service managers, they are FULLY aware about the VQ35DE burning oil problems... N

Mine was early at about 65,000kms. I am now at nearly 80,000kms, and been burning oil for nearly 15,000kms. I think even if hte leak was repaired, as a result of the multiple times the oil level dropped, I think my engine is already damaged.
I have symptoms of poor fuel economy and loss of power.
