Cracking noise under the hood on the right side from the driver?

Question

There is an occasional cracking noise that happens not very often and it lasts for about 3 seconds but it is quite loud. It comes from the right side of the driver seat under the hood. I have not figured out what actions cause it - I am trying to test if its transmition, AC, wipers or brakes, but still I have no idea when and why it happens. Sometimes I am scared for that noise and worry that it may not stop. Last time it lasts for about 4-5 seconds. I felt like pulling over worring about engine blowing up or other. Let me know what that might be. Thanks.

Answer 1

Keep track of what your doing, how you are driving, just before it occurs again, as there is something that is causing it and that something will help you to find it.

Not likely that you would hear a spark plug wire shorting from inside the car as they usually don't make that much noise.

Have you looked underneath it? a full and thorough visual inspection? try that....

Answer 2

Open the hood. You don't need to be a mechanic to figure out if something doesn't look quite right. A broken part is broken. Check your electrical lines that go to the spark plugs. They may have a crack in their skin. and the cracking is a spark jumping.
