Replying to: tripj (Oct 01, 2009 9:12 am) Your engine will not start when the cylinder is wet. If the leak is bad enough you will get Hydrolock and BOOM. Temporary fix with head gasket sealer in 100% water solution.  I think you will need new engine because you let the head gasket leak for such long period of time.

Replying to: electricdesign (Oct 03, 2009 6:39 am) so after I got it to start, I took it to the mechanic. He couldn't replicate the problem (it kept starting) but from the diagnostic he developed a couple of theories. Mainly, one of the sensors that tells the car how much gas will be needed to start the car(due to outside temperature) was messed up. He replaced that sensor and re-learned the idle, which was high. He also told me he saw no sign of head gasket damage-no leaks, no coolant in exhaust. I've had the car back for over a week and have had no problems whatsoever. I'm still nervous, but keeping the proverbial fingers crossed. Replies to this message: electricdesign (Oct 16, 2009 10:52 am) rondhol (Oct 19, 2009 10:16 pm)

Replying to: tripj (Oct 15, 2009 7:30 am) Let's get the whole story straight please... You just posted that your mechanic said "he saw no sign of head gasket damage-no leaks, no coolant in exhaust", But remember back in your first messege #470 on sept 17, you said "At a "free" car clinic at my dealership, I was told that the head gasket needs to be replaced ($1,600) because coolant is seeping in and causing the misfires". I assumed that they gave you a positive diagnosis of the head gasket failure. That situation DOES NOT CHANGE. Just because your mechanic does not see signs of the head gasket leakage, does not mean it is not there. Remember, by putting the sealer in the cooling system, it MASKS or HIDES the symptoms of the failing head gasket, but PLEASE remember it is ONLY A TEMPORARY REPAIR. How long it will last is anybody guess, 2 weeks, 2 months, 6 months?? But the day IS coming when it will get worse and the symptoms will come back and not go away and the engine will fail. You are kind of fortunate in a way, because this gives you some time to think about this and try to plan what to do, not like it was a sudden failure that cost you $6000 for an engine RIGHT NOW. DO NOT be lulled into a sense of false security just because the car is working ok for now. You should be feverishly working on a plan for what to do. I know what my plan would be if it were my car, I would get rid of that car as fast as I could before something else goes wrong with it. Putting money in that car is only throwing good money after bad. Get what money you can for it and then research your next car on the internet, and be sure to buy one that is PROVEN RELIABLE. Other immediate issues...the hard starting - The Altimas are known to sometimes have problems with the sensors and the MASS Airflow Sensor. Make sure that the Crankshaft Position Sensor and the Camshaft Position Sensor have the recalls done on them up to date and that they are working correctly. Check the MAF sensor to be sure it is clean and working properly. All of these things have been discussed in these forums, go back and read the past messeges, use the "search" feature to find what you want to read about using keywords such as sensor, etc. And finally, yes, I know about "keeping the proverbial fingers crossed" as I do the same every day, because my daughter is still driving her 2002 Nissan Altima 2.5S, and it scares me to death, especially now that I have been out of work for almost five months and have NO money to fix it. I say RATS of this darn Depression! I keep asking her the same questions almost every day, Did you check the oil today? Did you have to add any oil today? How much? Did you check the coolant today? Did you have to add any coolant today? How much? Yes, I certainly keep my fingers crossed, all the time! Again, Good Luck, E.D. in Sunny Florida Replies to this message: rondhol (Oct 19, 2009 10:16 pm)

Replying to: electricdesign (Oct 16, 2009 10:52 am) E.D, I am sorry to hear that. I also always check the oil, coolant, and any pinging/detonation noise. Tripj, the Head gasket need to be replaced ASAP or just sell it ASAP.   Don't waste your money and time to fix that Altima. I already threw more than $2000 to fix it in less than 1 year since 66k miles. (diagnostics, head gasket, CPS, struts, catalytic converter, engine mounts ). Exclude the $1000 maintenance like new brake rotors+pads at 80k miles, transmission+brake+ radiator fluid flush, inner+outer tie rod +alignment, new alternator (bad bearing) . I hate it's loud tapping noise during winter and lean pinging sound under light throttle + oil consumption.   I keep driving it with DIY maintenance for 2-3 more years. I am looking for a mechanics that can re-program the ECU to fix the lean detonation issue. I hate to go to STEALERSHIP (dealership) with $95 per diagnostic.

Replying to: jrc5 (Nov 03, 2009 7:55 am) Get new engine from 2004-2006 model and change the precat with after market header. Call Nissan 1-800# to check all recall (ECM-reprogramming, Pre-cat,etc) . If it is under 80k/8 years, you can get new engine + pre-cat from Nissan for free under Federal Emission Law. Replies to this message: mikola1 (Nov 18, 2009 7:10 pm) rondhol (Nov 21, 2009 8:01 pm)

Replying to: efitzgerald (Nov 06, 2009 9:45 am) REMOVAL      1. Remove the glove box assembly.    2. Remove the console side finisher (RH).    3. Disengage the filter cover tab to remove the filter cover.    4. Remove the in-cabin microfilter from the blower unit by using the pull tab on the bottom of the filter.
