No, you weren't too harsh on Nissan Canada. Some people are getting the shaft. One person I know...it took almost 9 months to get a new engine out of Nissan. Not good
A lot of it can be dealer dependant. I'm lucky to have a great dealer, with personal friends that work there.
I would call Nissan Canada ( or visit their US web site - can check the VIN #'s there) and have them run your VIN to see if you are affected by any of the recalls.
As for Nissan Canada
If they want to stay on top, they better give great customer sevice through any problems, even if it costs big $$$. This IMHO is the best way to earn repeat customers and customer loyalty. I'm on the fence right now as to weather I'll buy another. Time will tell.

thanks luvs2drive, I will get vin, I believe it is under the front seat as posted here back aways. I have more faith in Nissan America giving me a true recall history. My dealership is not service friendly as yours, I have driven NIssan in great faith for over 25 years now, I too question my future next auto purchase pending on how all pans out on this 03 Altima. I had trouble with a 2001 Altima which I was going to keep for 12 years, Nissan could not fix it in 3 years, let it go. I bought this 03 Altima in a second great faith and that faith is now getting shaken, if this 03 doesn't look like I can have confidence in it for the next 10-12 years then I will hit the Honda lots. Your right, this forum is a great source of info, without it I would be completely in the dark on my Nissan engine concerns, Nissan Canada or dealership is not enlightening me on any concerns, they seem to have their heads in sand. thanks

Taking the balance shafts out made little difference in the overall vibes from the engine. I still have the original engine mounts though. I have heard it can be a littly vibby if you get aftermarket stiff engine mounts with this mod though.
Overall, I can't tell a difference. I am driving a stock Altima for a rental car right now (my company car was totaled and I don't drive my personal vehicle for work) and I can't hardly tell any difference in vibes. The ONLY time I notice is if I cruise at 70 mph. Its a tiny bit vibey at that speed, but if you are at 65 or 75, your perfectly fine again.
I would do it again in a heartbeat. Where else can you get 8 hp gain, more oil cap., less weight, better mpg, and less oil wear for about 70 bucks, and a few hours under the hood?

Thanks Drivehard, that type of info is hard to come by.
OK. I couldn't get any dates on the new engines and internal design changes.
There is a concern though over the butterfly valves dropping screws into the motor.
I've found that some people with build dates of early to mid 03 (04 SE-R's) are still having issues with the intake butterfly screws coming loose. I did find out though that Nissan Canada's solution to this particular issue is to replace the screw, slap the motor back together, and send you on your way. I'll keep my ear to the ground though, as I still have a few avenues of info not yet explored. Time to dig deeper!

Okay, went into www.nissan.com the American Nissan website to post my VIN questions and I found a court dispute is going on between Nissan Motor Co and The Nissan Computer Division, no web site for commercial use except an email format for contact. Should I use this email contact to Nissan with VIN question or is there "another avenue" to contact Nissan on web, has Nissan Motor Company set up an alternative temporary web service? anyone know?
Thanks,

Cyprs here is what I found, so check your VIN and bug your dealer if you have to.

Just checked the air filter I popped in about 5,000 km ago it is clean and dry no sign of oil, is it safe to asume that there is no serious cylinder scoring and blow by??
Oil level in 350km since recal hasn't dropped a bit

Thanks Dominik, will check out the site and do VIN check. Glad to here the car is not consuming, my air filter is clear too, I am sure it was due to an overfill but not certain.
What exactly did Nissan do on the recall to stop oil consumption?
thanks again,
Cyprs

As for oil burning, you must go on a oil consumtion test. They keep track of the oil levels at given intervals, and if deemed too high, you should get a new motor. The issue of the cat causing this problem and what they do about it is listed in the recall. Bascially a ECU reprogram to minimize valve overlap and lean the mixture a tad. They also check the pre cat (but stupidly from the bottom, not the top where the issue lies).
As for the butterfly valves loosing a screw, this is something I would have paid an hours labour for to check, but they found one missing and also cat damage. Damaged likely by the screw hitting the ceramic core of the pre cat. The screw was never found, likely melted.
My car did burn Mobil 1SS 5W30 at a rate of about 1L/6000km. Normal, but not in my book. My new motor doesn't burn a drop of Mobil 1SS 5W30 in 9,000km!

I went to Dominik's suggested link, I found that my vin # does not apply on any recalls concerning the Cat, fuel screen, remapping or muffler. Basically nothing Nissan mentions on site for recalls apply to my VIN #, the American page says nothing about the loose intake screws though. I sent Nissan America an email with my VIN and asked about the hail damage, intake screw issue and if my cat issues are taken care of and if so, how. I asked them if my latter 03 QR25DE motor is a true Japanese designed engine like the 04-05 models,and if my latter 03 Altima has the same engine as 04s. I also asked if my engine has the Americanized bearings and rings or the true Japanese engineering. Will post findings for those with latter 03 Altimas.
I have had some slight oil consumption on this 03, could be from break-in, my 01 Altima with the 2.4 litre had some oil consumption too at Break-in period. I did find somevery small metal filings in oil drain pan at the 15K kms point on this 03, dont know if it is recall issue or break-in. What do you think of slight oil consuption and small filings at 15k?
thanks,

double checked, my 03 engine is on recall for Pipe Hanger Pin & precatalyst, my understanding is they inspect everything, if okay they do a remap and done in 3 hours, if there IS parts of the cat falling off it means new engine, guess I will find out, might as well get the intake screws checked too.

Cyprs...
Get them to remove the upstream O2 sensor for chekcing the cat. Looking in from the bottom is useless, and will only find a complete catastrophic failure. Get this recall taken care of ASAP.
Oh...and good luck with getting the info you wnat form Nissan! They may more than likely hand you a bucket of BS. If you learn anything positive, post it up!

Luvs2drive, how long a battle did you have to fight to get them to replace your engine? did they first replace the cat and reprogram ECU? and then monitor oil usage?
Cyprs, they replaced the cat and reprogrammed the ECU uder the recall that's about it but they did not say a word about inspecting the cat that was replaced, get yours done

Luvs2drive, 1 litre in 6000 km is pretty much borderline acceptable ( in most dealers' opimnion)
did you have any other symptoms like oiled air filter or smoking ??
I am a bit worried that they just will not wanna do anything and blame it on previous owner's poor
maintenance. They never said a thing about inspecting the old cat
But once the damage is done would the engine not start to use oil at much higher rate 1L/1,000 km for instance??

Yeah, I knew my oil issue was right on the border. I switched to 10W30 and it kept it to maybe 400ml/ oil change. Acceptable, but not...
I had no other visible symptoms.
I didn't go on a oil comsumption test. I had the recalls done a while previous. It wasn't until they removed my upper intake manifold (at my request for piec of mind)that they found a screw missing. That's how I got a new motor. When they took the motor apart that's when they found a crater in my pre cat. It was on it's way to complete failure. Good thing they found that, as I was just about to go on a highway trip. They said it may have failed on the trip. I just got lucky. Plus I know the shop foreman and shop owner.
All I know is a couple of people I know would dump a litre a week into their ride trying to keep up. They would have a horrible black oily stain on their muffler tips and they smoked!!

Luvs2drive, you had the recalls done a while before they took the engine apart and found a crater in the pre-cat?? Sounds like the recall did not solve much then.
Thanks, will get cat checked and get it done asap, will post Nissans response if anything. I just had my car in the Nissan shop a few weeks ago on other issues, why wouldn't my dealership tell me of this call back, they have to know of it, why would they risk thousands dollars possible engine damage in ignoring a few hours work to resolve my cat problem, don't make sense to me. They seem disinterested, I may go to another dealer who is. It knocks the ---- out of me to find this problem, I thought this 03 was my car for next 10 years, this is second new Altima in 4 years, first one was a lemon, I bought this one in good faith, now this with second one's problems it is possibly time to hit toyota/honda lots for a proven engine, cant go 3 new Altimas in a 5 year period.
Is it best to ask Nissan dealerships upfront that if the cat is deteriorated will they replace the engine no questions asked? I would rather ask before hand than engage a years worth war. The Nissan web page states that if the cat is damaged and dropping particles in engine then engine is replaced.

Cyprs
