When would permanent damage be apparent from driving with low oil with engine light on?

Can your check engine light go off by itself and you pass emission test?
No, the check engine light will not shut itself off. It needs to be turned off by a mechanic. If it is on when u go to inspection, your car will not pass
The light could go off on its own if the problem fixed itself and there is anough time for it to pass it's selftests enough time.
The above answer is incorrect. If the computer in the car does not detect the problem which caused the check engine light to illuminate in the first place after a certain amount of cycles the light will turn off and you will be able to pass emissions. Case in point: My '96 Cougar set the check engine light due to some emissions components failing. Specifically, the purge flow sensor. I replaced the part and did not reset the computer. After about 3 days worth of drive cycles the light turned off by itself.
What do your check engine light mean?
The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle.
Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.
If the light comes on there is a code. Have the code checked and fix the cause. If the light is on with no codes, then you have a computer problem.

umm... ok sure, that's one way...
P1684 just means that your battery has been reconnected within the last 50 starts, it should go away I'm trying to figure out how to fix code P0551 on my 2002 Neon it has something to do with the power steering pressure switch or sensor more than likely. My only problem is no one can make up their minds whether or not 2002 neons have power steering pressure sensors or switch hopefully you have better luck than me LOL

Can you access the fuel pump on a 2001 Oldsmobile bravada without dropping the gas tank?
Hi. I owned a 2001 Chevy Blazer and the fuel pump was located in the gas tank. It should be the same set-up. It was fairly easy to change. Lucky I only had a few gallons of gas left in tank when it went. That may be one of the reasons. The gas in the tank helps cool the pump while running. Also make sure to change your fuel filter annually. This allows the fuel pump to operate at maximum efficiency and not over heat due to trying to force fuel thru dirty filter.

Tune ups are getting very simple for modern cars. Many cars it is just changing the plugs and wires, as there are very few, if any, cars that still use a distributor. There may be a specified interval for changing the coil packs, but a lot of them can go for a very long time.
