Question about 2003 Nissan Altima

4 Answers

Burning oil Around 60,000 miles, my Altima started to burn oil almost within 600 miles of an oil change. My engine is now at 125K+ and I have to pour at least 1-2 quarts of oil in the engine per week. I had the dealership run at least 3 different 'Oil consumption tests' and was told the answer is to replace the engine. This wasn't what the answer I was expecting. Past problems also included one of two sensors burning, twice, front left headlight burning out almost 3 times, motor mount breaking. The vanity plate for the gear shifter even came undone, i'm wonder if this car is a true lemon the dealership doesn't want to admit in order to avoid spending 3 - 5 grand and owning upto to their mistakes?

    My dealer (Sansone in NJ) said my cataletic converter was bad. they said debri from the cat got back into the engine and scrached the side of the piston walls. Since then they have replaced the engine, transmission, both cat's. Then the check engine light came on and they changed the cat again. I LOVE MY EXTENDED WARRENTEE.

    I Have a 2003 Altima V6 I just replaced all 3 Cats on the car but I continue to burn ateast a qt of Mobile 1/week. Also seems that the head is overheating. I spoke to a nissan specialist who said the problem is pretty common with all Altimas. He also told me to change the valve covers because the baffles trap oil and causes the head to overheat. I am confused, I just spent well over $2000. on new cats and the problem still exists. The dealer does not care so this will be my last Nissan. Back to Honda/Acura

The 2.5 engines are no good aftre 180 km. Change the engine. You can find a used engine 50km+- for about $1000. I am at 190Km and i am looking for a new engine.

You have piston ring seal problems, a re-ring of the engine and new valve seals should cure the issue, but at 125,000 miles a new engine might be your best bet, contact some engine suppliers, you can get a much lower price than the dealer will ever offer for a rebuilt engine, look on the web under the heading of REBUILT JAPANESE ENGINES.

2002 nissan altima that starts but has low idea and when i hit the gas there is black smoke.

well black smoke means you are burning up engine oil. low idle means you have less compression. you might want to check your gaskets! does th engine oil level go down after a drive?

Blue smoke

Blue smoke (how many miles on engine, 50k or 500K???????
to some this means, burning oil, others steam
it that blue smoke lingers a long time that is oil burning
and smells just like oil burning.
and means 2 things,
1: engine burns oil.
2: if car had autotmatic trans the vacuum modulator love fail
and suck ATF fluid to the intake plenum and burn it, and bingo burning oil like mad.
3: PCV valve packed solid,and forces engine to leak oil or burn oil. or both. this is a 50k miles service point, skipping this?
4: gas in the oil making it thin and not sneaks past valve stems.
does oil change cure this.>?

now engines.
worn out engines smoke. (burn oil)
as do bad valve guides and seals.
and bad piston rings.
100 years same story, and miles matter. History on engine too.

My 2006 Volvo S40 does not have an oil leak but it is burning through all the engine oil in between oil changes. I get my oil changed about every 4,000 miles.

have you tried to run finger around inside of tail pipe to see if its burning oil!! but do this when it is cold. you may also have bad oil rings on pistons. if it is burning oil it will smoke very little if any. because the convertor runs so hot it will burn up all the oil residue. so you may noy be able to see any smoke. have a good day!! check carefully all gaskets for oil leaks, and also make sure oil filter is hand tight, sometimes a loose oil filter will start leaking oil.

Smoke comes out of the tailpipe when first

60,000 miles or so depending on the engine but if its blue smoke which it means its oil burning its sounds like valve guide seals.

2002 altima burns oil about a quart every 300 miles. I Just got this car engine is very clean . I had oil changed and they talked me into haveing an oil flush ran through the engine with the oil change....

Check your muffler, is it thick black? The engine is burning oil, you need new engine if the cylinder ring is bad (compression test), and new catalytic converter that poisoned by excessive oil.

Many altima 02 has pre-catalytic converter failure that cover under 8 years/80k miles emission law. The materials in the pre-cat destroy the engine. It is well known problem and you can get new engine under this warranty

2001 Toyota Corolla, Burning Oil rapidly

hi, the main cause of major oil consumption is due to cylinder wall deterioration. this is caused be bad piston ring sets that tend to chip of tiny pieces of the cylinder walls over a long period of time. this will start to show in engines with high millage. this will also lead to compression loss as well if it is not fixed soon.

To fix this issue within the cylinder walls, they will have to be machined and a new set of piston rings will have to be fitted around each affected piston. this will stop the oil from leaking into the combustion chamber and it will restore the compression rate as well.

I have a 2004 Nissan Sentra SER and 2 months ago i started burning oil i only have 60,000 miles on the car and other than the oil the car runs great. any suggestions on what it might be?

most cars will burn about a quart between oil changes when they get a few miles on them this pretty normal as long as you dont see black smoke or oil on the ground i would say its fine
