Just got back from Tyson's nissan. The tech checked for the second time that the oil was 2Q down after 1500miles. Service manager is going to give nissan a call and get the approval to get a new engine. Hopefully I'll get the good news on monday.
The new motor part number I should be looking for is 10102-AC7MZ right?

 

goodluck! Infiniti denied replacement of my motor because of my exhaust system. My car takes 3qts/1k miles.

 

wow thats crazy. why dont you take the exhuast off and try again?

 

Got 12k on my new block so far and have since added a turbo. Running like a champ! Good luck on the replacement block.

 

Nissan is famous for putting flags in the system, so if you take the exhaust off and go back, they will see in your service records that it was on at one point and most likely contimue to deny your claim .

From my understanding, the info is shared between shops on a nationwide system.

 

I smell a lawsuit! That is complete bull.

 

OP, did you have any mods when you took the car in for testing??

Arbitration is the next step. Just waiting for a response from the Infiniti legal dept.

 

just got my engine replaced last week from brown's nissan.. same problem oil consumption

 

^ And I am sure you rolled in all modded too!

 

yep, and they didn't say anything to me about that...

 

no mods..

 

so is nissan gonna replace it again?

 

don't know yet cuz i checked and it looked to me like i'm short a little bit of oil... i'll bring it in again so they can run the test...

 

^ Its amazing how some dealers, even service writers can excuse mods and others use it as an excuse to tell you to get lost.

 

they denied me because my test pipes make the car run too rich which destroys the piston rings,well thats what they say,but well see what happends in court....

 

I would say to make up a petition with people to sign that they run test pipes and have not had an issue, but then everyone on that list would get a visit from the local PD looking for cats lol

 

wow, what year are these engines that consume oil? Mine doesn't have a single problem. 03 with 74k miles. The most oil i lose in a month is a few teaspoons out of my catch can.

how do test pipes make the car run too rich? wouldn't it lean the mixture up because of the increased exhaust flow? my car went lean when i added test pipes.

Also, adding more fuel wouldn't burn up rings. It would actually cool the cylinders better for reduced wear. That is to an extint. Once you get super rich then it will screw other things up.

 

i have an 04 g35 automatic with 54k miles. Very rare problem for this year and automatics but i guess i have terrible luck.

 

Damn sucks to hear this, I got rid of my Z for this exact same reason. Oil consumption, stupid crazy on my 06 manual z. Engine was repalced only AFTER a nice case was opened with BBB. They contacted Nissan and a week or so later new engine which made the issue worse and then my transmission kept grinding gears. 2 years of headaches, one can only take so much drama from a friggin car.

 

Since when do 2004s burn oil?
