    the timing chain cover will not just fall off,it is glued on with a special sealer, it will be very difficult to separate from the engine, use a thin blade of some sort to pry between the cover and the backing, DO NOT KNICK OR OTHERWISE DAMAGE THE ALUMINUM COVER! be very careful pry slowly around the whole cover.

    HERE IS THE SET OF INSTRUCTIONS FOR REPLACING THE CHAIN.





    Instructions

    Things You'll Need:


    • New timing chain

    • Basic automotive tools


      Remove Your Timing Chain

    1. Step 1
      Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Altima is 60,000 miles.


    2. Step 2
      Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.


    3. Step 3
      Drain the cooling system and disengage the negative battery cable. Undo the spark plug wires and set the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.


    4. Step 4
      Disconnect the engine undercover, vacuum and fuel hoses, harness and connectors, drive belts, power steering reservoir, alternator and bracket, upper radiator hose, air duct, front exhaust tube, intake manifold collector supports, collector and exhaust manifold and the distributor.


    5. Step 5
      Prop up the oil pan and take out the front engine mounting, the valve cover, camshaft sprockets, cam bearing caps, camshafts, cylinder head bolts (reverse the installation order), cam sprocket cover, upper chain tensioner, chain guides and chain, idler sprocket bolt, cylinder head, intake manifold and cylinder head gasket and the steel oil pan.


    6. Step 6
      Place a steel cutter between the steel and aluminum oil pans. Slip the cutter around the oil pan's edge. Disengage the steel oil pan, baffle plate, oil strainer and the front tube.


    7. Step 7
      Secure the car on jack stands and place a seal cutter in between the oil pan and cylinder block. Slip the cutter around the oil pan's edge.

    8. Install Your Timing Chain

    9. Step 1
      Reconnect the crankshaft sprocket, oil pump drive spacer, idler sprocket and lower timing chain. Position the lower timing chain on the sprockets and line up the mating marks.


    10. Step 2
      Rub on an unbroken bead of liquid gasket and put in a new front cover and oil seal. Secure the bolt at 105 to 112 foot pounds (142 to 152 Nm).


    11. Step 3
      Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.


    12. Step 4
      Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.


    13. Step 5
      Refill the cooling system and add clean oil in the engine.


    14. Step 6
      Hook up the negative battery cable and any other disconnected parts or items. Start the engine and look for leaks.

SOURCE: replacement of a head gasket on 2.5 liter nissan altima 2002

frajogag: First off, be aware that these bolts are "torque to yield" bolts (streach bolts). What this means is that instead of torqueing the head bolts to a specific torque specification, they are torqued down to a set spec and then tightened by rotating the bolts a certain angle, like 90 degrees. and all of them are turned the same amount.
This means that the shanks of the bolts must be checked to make sure they are not too thin (or the bolt has already stretched beyond limits and is prone to snap if used)
Here is how you check the bolts. Measure the bolt using a micrometer, at the base, or within the first 13mm from the end where it threads in. Then go to about 10mm before the threads end heading toward the top of the bolt. There should not be more than a 0.23mm (.0091 inch) or less difference or the bolt should be discarded.
Torque the bolts down to 98.1Nm ( 72.ft lb)
Looking at the head from the side, so you are looking at the full length from side to side, I will number the head bolts in this fashion.
#1 & 2 are directly in front of you and in the center of the cylinder head crossing it width wise.
#3&4 are to the left of #1&2, / #5&6 are to the right of #1&2
#7&8 are to the left of #3&4 / #9$10 are to the right of #5&6
Now, you have the sequence.
After the initial pull, back off all the bolts in the same sequence and then retorque them to 36 Nm ( 28 ft lb)
Using a torque angle wrench or having the ability to accurately judge turning angles. Rotate (clockwise) to a 75 degree angle. do this to all the bolts using the sequence I had provided.
Rotate the bolts (clockwise) 75 degrees again on all bolts in the same sequence. The proceedure is complete!

SOURCE: 2002 Nissan Altima Exterior Door Handle

I seriously doubt that supergluing or even epoxying a handle back will hold at all, or hold for more then few days.
I would only suggest doing the replacement yourself if you familiar with this type of work, or has the aptitude to figure out how to do it, and have the right tools because it is NOT trivial and a number of things can be done wrong, broken or scratched.
The handle itself cannot be replaced. The outside door handle assembly (which includes the handle, the bezel with all associated springs, plastic and metal hardware) has to be replaced. Besides junkyards, which is a long shot for number of reasons, the only place where the handle assembly can be bought is the dealer. And these handle assemblies are not cheap ether. The driver side handle on my 2002 Altima broke first. I paid $60.23+tax, and they had to order it. BEFORE anyone goes to the dealer I suggest to call first, and ask them if they have it in stock. Since door handles are sold painted they will ask you for your car's VIN number so that they match the paint color.
After you pick it up, the replacement will take about an hour (if you know what you doing). The inside door panel has to be removed, it is held in place by the inside door handle and the panel is attached by a number of clips, the handle assembly is attached to the door by three bolts, to remove which you will need a socket with extension. You will also need a good flashlight so you see what you are doing.
If you are familiar how to do this type of work and plan to keep the car for a while I strongly suggest buying a factory service manual on a CD (I bought mine on eBay for under $10). It is worth its price 1000s of times over, and makes almost ALL repair work SOOO much easier.751424a.jpg73e3811.jpgd240851.jpg

DOES A 2002 NISSAN ALTIMA HAS A TIMING BELT


No timing belt. your Altima has a timing chain. No service necessary unless the chain is stretched out. I have seen just a hand full of those since they came out, so you should be safe. You will get the check engine light to come on with the p0335 cam position sensor to come on in few cases that I have seen and it was a stretch chain. other than that no real issues with timing chains.

Does 2007 altima 3.5 have a chain or timing belt


After 2002 Altima offers two types of engine: the new 4 cylinder 2.5 L QR model engine which is fairly powerful (175 horsepower) and, I believe, one of the best engine in its class the 3.5L V6 VQ model engine with 240 horsepower. The same V6 model as in in the Nissan Maxima, Pathfinder and Murano.
Both engines feature continuously variable valve timing using a silent chain instead of timing belt. Throttle cable is gone - the throttle operates electronically by wire based on gas pedal sensor readings. This design provides smoother transmission shifting and lower emission.
The 2007 Nissan Altima 3.5L Sedan, has a Timing Chain, and an Ignition Coil Pack. NO DISTRIBUTOR.

Nissan altima


timing belt is the only one that would make it rattle because its pre detonation which is timing is too fast. If there wasn't any other codes.
If it was just a rattle it would do it all the time
