The sound should be random, meaning that it probably won't do it every time the car is turned off. Most of the time people notice it after they install an aftermarket intake, or filter. Sometimes people will notice it after removing the stock intake resonator, and leaving the stock intake box and filter. If you think that the sound is not normal then I would look over all the vacuum hoses and make sure they are all connected and tight. While the motor is running put your ear close to the motor and move around slowly listening for a whistle noise. If you don't see or hear anything from the vacuum hoses then you are fine.

Exactly.

Mine isn't random, it happens everytime, and i have a stock airbox. The honda mechanic said that it was normal also, just compression from the cylinders. However, how come it just started happening like a month ago, when i've had the car for a year? I found what looked like a vacuum hose sittin near my fuel rail last week, i couldn't find where it goes tho.....

Is it comming out of the valve cover? Is it comming out of the Intake manifold? If not hten were is the end that is still hooked up?

[mikester_91]

neither end was hooked up, it was simply sticking straight up in the air, neither side hooked to anything. I think it was smooshed inbetween my fuel rail and intake manifold.

So it won't come out? Do you have a digital camera? If so try to take a pic and maybe I can tell you what it goes to.

I'll try to get a pic of it.

I can now assure you this sound after turning the car off is NOT related to the air intake; it now lasts long enough for me to turn the car off after a regular drive and pop the hood and still hear it.

It's coming directly from the headers it sounds like. MAYBE the block but I seriously doubt it. I have pretty good hearing and depth perception and I'm pretty sure it's the headers but as always I could be wrong.

I can also better describe the sound to you:

After the whizzing (not the constant low hummmm my intake makes) sound dissapears in 2-3 seconds:

It sounds exactly like water hitting a dry metal pan. Every drip is 1-2 seconds apart initially. There are 5-10 drips, and then a loud CLICK!
then the dripping starts again, but slower. then the CLICK!
slower again, click again, til the final click in which all sounds stop.

All this is AFTER the initial 'fan whizzing' sound immediately after I turn it off.

Helpppppppppppppppppp!

If it sounds like liquid hitting something than it is probably oil or coolant dripping on the exhaust pipe under the oil pan. Have you looked on the under side of the oil pan to see if it has any liquid on it? Also look to see if there is any burnt lokking spots on the exhaust pipe, or any discolor specific to one area.
