With great care and attention!
The fact that you have to ask this would suggest to me that maybe you should entrust such a job to someone a lot more mechanically minded. Then again, I wouldn't be where I am today if I didn't have a burning curiousity to take apart machines that I didn't have any true knowledge about.
In the very least, purchase/borrow/hire a repair manual (eg: Haynes) for a 1997 Nissan Altima - which looks a lot like the Nissan Bluebird here in Australia - and get yourself a torque wrench. Overtighten or undertighten the tappet cover or other essential parts held down by bolts and you could be left with a big piece of scrap metal under the hood/bonnet. A good repair manual will tell you step-by-step how to dismantle an engine and should give you the correct values for tightening all bolts.
You will also need a socket set, ring spanner set, perhaps some Allen/hex keys...
Drain all the coolant and oil before opening an engine. You may potentially contaminate both and cause an amusing/frustrating spectacle for other road users once you finally get it out on the streets.
I have been told that when you open up an engine, especially a modern one, you have to replace the rubber seal (gasket) for the head, as well as being a good opportunity to replace any exhaust gaskets, O-Rings, etc... I am not positively sure about this, but do consult someone with a bit of wisdom about pulling apart car engines and save yourself a lot of hassle.
something wrong on the engine get it chek for any codes
I am having the same problem with a 1998 Nissan Altima. The engine runs fine at idle. When you press the gas the car stalls out. I'm down to replacing the gas pump in hopes of fixing this problem.
There are pages of things that will turn the check engine light on. You need to have it checked for codes.
starting with the redesigned 1998 altima the engine crankshaft was balanced much better to reduce vibration. we have a 1993 and a 1999 altima with the same engine and the 1999 is so smooth at idle i sometimes can't tell if it's running.
Use an automotive computer code-scanner to read the stored code. Then you'll know why the "check engine" light is on.
One way would be for the check engine light to illuminate and spit out a code P0300 for a random misfire.
Bad sensor have it checked. Depending on the sensor you won't have any real problems for a while
In my 2001 Nissan Altima, my oil filter is located on the side of the engine closest to the interior cabin. In addition, it is on the passenger side of the car. Probably close to where the glove compartment would be. It is very hard to see and you will have to be underneath the vehicle. Also, the oil filter is kinda small.
There is no error code PO329 for a Nissan Altima. The closest codes for this would be P0335 which is the CKP Sensor or P0340 which is the CMP Sensor, Detectable Or Undetectable Circuit.
You can find a 97 Nissan Altima alternator schematic diagram in the vehicle's owner's manual. You can also check local auto part stores.
