Hello E.D. Been working with my mechanic on the 02 Altima engine with excessive oil consumption. He got access to Nissan's technical database and discovered there is a voluntary recall on this engine, for a certain range of VIN's, with excessive oil consumption. I'm guessing "voluntary recall" means it's not mandatory, and if you find out about it, Nissan will fix it. There is a four part process that the dealership has to go through to qualify your car for a complete engine replacement, paid for by Nissan North America. Prior to this, I have been in touch with both the local Nissan dealer and Nissan NA, neither of whom offered up this information. I'll be getting the actual printout of the database Wednesday so I'll have more info then. Sounds hopeful, but we'll see if I'm getting my hopes up for nothing. I'll post here what I find out, including the VIN # range. I'll also try to point you to the tech bulletin number so you can take it to your mechanics at the dealerships. More later.

jd10013,
Thanks for the link. You've obviously read the same bulletin I received. Called the dealership where I bought the car new in '02 and they informed me I already had the recall work done back in '03. And yes, you are correct, they did the reprogram, "checked" the precat, replaced the heat shield (which has rattled incessantly since) and changed oil/filter. I asked "what happens now that it's obvious that the precat has failed and I am using 1 quart/200 miles?" Dealer got a little testy, said once the recall work was done they had no further responsibility, and suggested I bring it in for yet another $164 diagnostic. I'm really tempted to trade this car in, but have too much of a conscience to stick the next owner with this problem. Besides, I really like the car but know it's going to quit on me eventually. A quandary!

If you have to empty out the pre-cat to keep it from eating up the engine, you can do a mod to the second oxygen sensor to make it not light the CEL.

Thanks for the link to the precat mod.
 
For readers with 02 Altimas with this problem, here's a link to the NissanHelp knowledgeBase.

Once there, you can enroll for free, then put NTB03-070c into their search field to get the recall info. It may get you nowhere, but you can at least see what Nissan knows about this problem and take it with you to the dealership to argue for a fix.

What I found interesting, and others in in the forum I linked to tried was, take it in under the 80k emmision warranty. thats what one of the people in there did, and got a new engine because of it. oddly enough though, nissan put the same exhaust back on
 
Anyhow, as the people in that forum have concluded, your best bet is to either remove and replace the exhaust manifold with an aftermarket one, or simply hollow out the existing one. in either case, because the car has another cat farther down the exhaust, you wont run into any inspection problems. hell, considering if you don't you could end up having to buy a new engine, even if you had to pay someone to do the cat stuff, it would be worth it IMO.

exhaust ploblem by 0506colix

Hi, im new I have been reading all of the problem altimas have. I have a question hopefully some one knows the answer. I was driving my 06 altima 2.5 on the freeway when i got home it smell burnt, i poped the hood and saw my exhaust manifold red hot it was glowing red. I search for recalls found that they have one for engine and engine cooling. So i took it to the dealer they put in a new Exhaust manifol catalyst and reprogram my ECM. I drove my car around for 30 minutes in city streets at about 50mph, got home and it was the same thing and same smell. I was woundering is it normal for it to get that hot to turn red or is there something wrong with my engine. thank you.

NO...The exhaust manifold should never be that hot under normal driving conditions....you still have a problem!

You may want to check your coolant level and the engine oil level. Make sure both are adequate.

'04 2.5 liter spark plug damage by cisco2004

hey folks,
i am new here. Over the last 30,000 (approx) miles i have had the same problem twice. A spark plug gets damaged while driving.The first time i had 113k miles on it. The mechanic said the gap between the electrodes was reduced to a minimum. This was the #4 plug. He regapped it and i drove on for the next 30,000 miles. This weekend it happened again. I was out of town for the weekend, it misfired and i went to another mechanic. This mechanic shows me the plug and again, the plug no longer has a gap. But it was from the #1 plug and this time I buy 4 new plugs. Twenty miles down the road, it happens again. I get back to the mechanic, fuss a bit, and he takes a look. Again it's the #1 plug and the new plug is damaged. Now other mechanics there are looking and offering opinions. One of them grabs a magnet and runs it down the valve and goes fishing. He pulls out a small piece of loose metal that must have been the culprit. Now it drives fine like it always did. What gives? What is falling apart and how long before engine failure? Any thoughts?
