The Nissan Altima, admittedly a nice looking car, is a piece of crap. I have a friend with a 2004 2.5 and it won't pass state inspection and the engine is about to blow. The car was manufactured with a defective catalytic converter that comes apart and gets sucked into the engine and causes engine damage. Nissan knew this yet still produce this lemon for at least 5 years. The part has just recently been changed. Apparently it only affects the 2.5, but considering the total "fuck you" attitude Nissan shows on this matter, I personally wouldn't buy shit from them.
If you own an Altima 2.5 and it's using alot if oil and water, you should prolly sell it while you can. Just a friendly psa!

Noted, do not buy shit from Nissan. Only buy Toyota or Mitsubishi manufactured faeces.

Everybody makes shit from time to time, but to continue to sell a piece if shit for 5 yrs with the same major defect is just fucked up. Then they make YOU pay to prove you have the damage only to say "yeah, we're not gonna do anything about that". Assholes. But they'll get theres. Wait and see.

While I agree with not buying Nissan, I think you have your facts wrong. I used to be a Nissan/Infiniti grease monkey, and their product is overrated, but not at all substandard.
And while catalytic converters do sometimes go bad, it is impossible for parts to 'get sucked into the engine'. The converter is part of the exhaust system, well past whatever is happening in the engine, and it does not recirculate. So any mechanic who claims that pieces from it are harming the engine are either lying or incompetent.
Now, having said that, a clogged/defective converter can cause the engine to run poorly, due to inefficiency and poor flow, which can trigger several fault codes and a noticeable loss in performance.
Hope this helps some...it's just frustrating to see people suffer from bad information, and head off in a wrong direction

Excelente thread, an alert, here, Nissan has a factory and produces four different types of vehicles:

- frontier.

With all due respect Mr Grease Monkey, my facts are not wrong. I know where a cat-con is and what it does. It made little sense to me to, but a little research will show this to be true. I've even read somewhere how particles get sucked in the exhaust, but since I'm on my iPhone finding that on the web would be a bitch. It's irrelevant anyway. The fact is that the cat (technically it's the pre-cat) is a piece of shit and it is causing engine damage. Go to Nissan and talk to someone above grease monkey level and they will tell you so!
The first code my friend got was for ox sensor. When I removed the sensor it was sheared off. I took it to O'reiilly and the guy looked at it and said "You've got engine damage. Your catalytic converter is coming apart, that's what ruined this sensor. I know. I used to work at Nissan"
Then the car started coding for the cat, which is a dealer item only, but until recently, even if you replaced it you were gonna get the same defective pos because the assholes never changed the part.
I'm just trying to help other people so if youre not gonna be helpful please stfu, because YOUR ignorance is not helpful. Go buy one and see what happens!

Yeah, Nissan is not as good as it used to be ever since they moved some of their factories to America. Some of its models are actually manufactured in the states (Altima is assembled in Tennessee) so knowing all our pathetic labor unions you can expect poor quality. All the Altimas and Maximas you see today are basically American pos's under a Japanese badge.

However Nissan still has a few top buys like the 350z / 370z and all Infiniti line ups, which are all manufactured and assembled straight from Japan, robots and all, and as seen from their superb reviews you can expect quality and reliability.

My friends 95 300zx is probably one of the most reliable and awesome cars in the world and the tt engine is still running strong without so much as a hitch.

As I would've theorized, the problem stems from the fact that the 2.5 powerplant has a small valve overlap, so the exhaust valves are still open briefly during the intake stroke... That's how an exhaust can suck (literally)! And that's prolly why the 6 banger doesn't have this problem.
I thought I wanted a Z or the Infiniti equivalent, but this kinda turned me off. If you think about it, you don't see alotta older Nissans!

:( Same thing happened with the Dodge Intrepids of 1999-2002, the 2.7 engine came with an area where sludge would build up near the oil pump , and even if you kept if with new oil, did oil changes and plenty of oil, the engine would still seize up. Add that to the fact that it was a small engine for such a big car, causing a lot of cooling/overheating issues.

Stupid Dodge would not even replace the engine even under full coverage warranty. They would say it was caused by you not doing the oil changes on time, with them. If you did the oil changes yourself, or other reputable oil change/lube business, Dodge would claim that those people did a substandard job. Never buying a dodge again.

Engine & car size are not going to cause over heating.

If there is overheating something is wrong. Either the cooling system is leaking, the radiator fins have corroded off, the system is full of crud, the cooling system isn't getting enough airflow, the water pump is being spun the wrong way, or the cooling system itself were simply underdesigned.

@staggerlee- Totally Agree

ox sensor? you mean oxygen sensor...nothing but an input signal to the computer telling it if the Air Fuel is too Rich or Lean so the computer can correct it,the cat cant fuck these up-contamination such as coolant or oil etc. can and time kill o2 sensor...sucka before you talk out your ass at least ask if anyone knows cars and blah blah blah.... because your OFF POINT

Not that I started this thread to argue about what people think they know about cars, but what did I say about an oxygen sensor that you think is off
point. Surely you're not thinking because I wrote ox instead of oxygen I don't know what it is. I woulda put O2 but that looks silly without the subscript 2. Unlike you jerks, I rarely go off half cocked. I would not have posted this if I didn't know what I was talking about. Now I don't know how much you know about cars and don't assume you to be an idiot like you wrongfully do me, but since we're making dumbassed unfounded guesses, I'm guessing you're one of the thousands of people who have rebuilt engines and shit BUT STILL DONT UNDERSTAND SHIT!!! There are plenty of mechanics who can fix the hell outta your car that don't understand how it works. All most mechanics know is what they've done hundreds of times.
Like I said before, this is a PSA to anyone who owns a 2.5 Altima, and if that doesn't apply to you or you just wanna spread some negativity, please (last time I say please) keep your ignorant comments in your ignorant head.
Oh and do you mean newb? I don't know what a nub is I guess anymore than you know what a ox is.

I may not be able to answer your questions about the proper offset for your 22" rims, but I guarantee I'm infinitely more knowledgeable about the 2004 altima and it's exhaust system. So don't just throw rocks, ask questions, that is if you know enough to ask.

I know what I said and I know all of it's true because I lived it, I didn't read it in some book. Do you know anything about the Altima cat-con? Do you know where it is? Do you know where the O2 sensor is located? Fuck no, you don't! So before you start telling me what I don't know why don't you figure out what YOU don't know.
And I've been to Nissan forums that's where you'll find out that the engine does indeed suck shit in from the cat!!!
I don't know everything, never claimed to, but I know this fucking exhaust and you don't! I also know it was recalled on Canada, because it does exactly what I said it does.
Now you can continue to believe shit don't stink, who gives a fuck! If someone benefits from what I warned them about great. If they're bullheaded like you and buy this piece of shit anyway, then I tried. That's all I can do.

Engine & car size are not going to cause over heatin..... or the cooling system itself were simply underdesigned.

exactly what I said. The engine runs hot because of the load of the size of the car, so it has to have an adequate cooling system. Which, on the Intrepid, *I used to own one* is tiny. So yes, that's why I insulted the Intrepid engine and it's cooling system as inferior.

I used to see a couple old sentras around. But cash for clunkers have dramatically reduced most old cars in general. However as I said the authentically Japanese Z and Infiniti line up are completely different Nissans especially when you're comparing them to the Tennesee built Altima. Have a look through consumer reports or any car review site to see the types of awards the Z has won. Personaly I think the Z is ugly and getting an entirely different car would be a good idea. I would get anything AWD, preferably a rally car.

It's ok, I got it. For some reason people here just like to argue points that are unarguable. The dodge Durango is supposedly known as having a sludge engine. I have a friend with one of those, and a friend who just bought an avenger. I hope it works out for her.

I have much disdain for awards. They're so skewed and political. Everytime I see that commercial for the Altima saying it's rated number 1 in initial quality I start fuming! But it is a great car for about a year, so I guess they didn't lie. And they have changed the defective part finally so maybe it's better now. I really want a used Toyota Supra, but they are way over valued, so I thought about the Z. I like the G35 better, but I don't like the new styling (G38?) and it's outta my price range anyhow.

You've had plenty of time to formulate a theory. It only took you a minute to shoot down what I said. Why is it so hard to explain why what I said was wrong.
Yes I would be a fool if I thought I was smarter than everyone, but I don't think that. I can learn something from everyone. You're the one who acts like he knows everything, which you're right, makes you foolish.
I am certified, but my "certs" are federal.Im never going to take you seriously dude you reply sarcastically so you get an asshole reply, nothing more nothing less but to indulge you...when a cat goes bad it rattles like all hell heres a pic of the insides of a cat...nothing in it can make an 02 sensor go bad but a Bad 02 sensor can make your cat go bad by over saturating it with fuel, they have limits and can only do so much.

OK, now go back and read my posts. Altima has a cat and a pre-cat. I said technically it's the pre-cat that is coming apart. Any particle that can damage cylinder walls, which is what it is doing can certainly damage a sensor. I never said the sensor went bad. I said the tip was sheared off! So hot oil broke the tip off the sensor? Or maybe there are moving parts in the exhaust I don't know about. You don't have to watch CSI to tell something hit the sensor... I can show you a pic when I get back home.
Like I also said, I didn't pay any attention to the sensor, it was someone else who pointed it out to me and told me it would be a waste of time replacing it because by the time you get it to be inspected that ones going to be damaged. But everybody's wrong and you're right. I'm sorry.

As I would've theorized, the problem stems from the fact that the 2.5 powerplant has a small valve overlap, so the exhaust valves are still open briefly during the intake stroke... That's how an exhaust can suck (literally)! And that's prolly why the 6 banger doesn't have this problem.
I thought I wanted a Z or the Infiniti equivalent, but this kinda turned me off. If you think about it, you don't see alotta older Nissans!
I used to see a couple old sentras around. But cash for clunkers have dramatically reduced most old cars in general. However as I said the authentically Japanese Z and Infiniti line up are completely different Nissans especially when you're comparing them to the Tennesee built Altima. Have a look through consumer reports or any car review site to see the types of awards the Z has won. Personaly I think the Z is ugly and getting an entirely different car would be a good idea. I would get anything AWD, preferably a rally car.

I have much disdain for awards. They're so skewed and political. Everytime I see that commercial for the Altima saying it's rated number 1 in initial quality I start fuming! But it is a great car for about a year, so I guess they didn't lie. And they have changed the defective part finally so maybe it's better now. I really want a used Toyota Supra, but they are way over valued, so I thought about the Z. I like the G35 better, but I don't like the new styling (G38?) and it's outta my price range anyhow.

I used to be stationed in Tokyo at Yokota Air base, where all japanese sports cars were cheap as hell except for the insurance. I had a Nissan Silvia at the time because it was naturally aspirated. But yeah Supras will definitely be overpriced on US soil just due to its rarity and hype. Its production ended years ago. Dont buy one here unless its in perfect factory condition and the highest end model. Also chances are itll be modified and you dont want that. So its worth it just to import one rather than looking for one here.

Never really considered import route. Can you get a lh drive? Yeah I know most of 'em are modded. There's a place back home that specializes in them-- that's all they sell and claimed they'll find what you're looking 4, but I haven't been there yet.

Probably not but im sure theres some costly conversions in case you like drive-thru as much as me.

Wouldnt get one as a daily driver.

The Altima must have won a top prize because it's sure screwed you.

I hear that mechanics are into S&M because they like to put the car onto the Rack and then crawl underneath and use their tool.

It appears the precat is too close to exhaust manifold. Someone else said the car runs rich. At any rate, precat gets too hot, stressed beyond it's design parameters and it's guts start coming apart. Then, since the exhaust valves are used in lieu of a egr valve, the particles are sucked back into the engine on the intake stroke. Now I don't know if all this is happening. What I know is: the O2 sensor I took out was beat to hell. The car has been using oil and water like crazy since the car was less than 2 yrs old. It's been coding for cat since car was 2 yrs old. Everyone I've talked to who owns the car puts oil in it all the damn time--- except the ones who lost an engine because they didn't check it everyday.
And I know Nissan doesn't give a fuck and their customer service sucks! These are things I know. All the other stuff is what I've been told and read.
If you see an Altima with this engine, I bet it's fucked or will be.
