Q: Strange noise coming from under the hood.

asked by on

First off, I do know the car. It's a 2001 Ford Falcon AUII XR8, Falcon wasn't listed in the options under 2001 Ford.

There is a really concerning noise coming from under the hood of my car; it sounds like the noise when you release air from a balloon while stretching the escape from side to side, or if you were to have a rubber tube from a bike tyre being pulled quickly across a smooth metal surface

This problem seems to occur when the revs are at or above approximately 2,500. When it does happen, the car loses an incredible amount of power and the higher the revs go, the more intense and louder the noise gets. The problem tends to stop once the accelerator is released and about 2-10 seconds pass.

My mate originally thought it would have been a problem in the gear box and we tried driving in first, second, third and just drive, but it still did it in every gear. Things like oil, water and whatnot are all up to check as far as I'm aware.

Thanks for readin' - Eugene

Hi there. Check all of the intake hoses and make sure that they are all tight. The sound is when air is leaking through the air intake tubing going into the engine and can create a loss of power at high rpm’s. Also, if the engine has a vacuum leak, it can cause the same sound and also have a loss of power too. Check all piping to the vehicle and check all of the vacuum lines and make sure that the vacuum booster is sealed tight. Fix or replace any broken vacuum lines and tighten all hose clamps to the intake. If you need further assistance with the balloon like sound from the engine compartment, then seek out a professional, such as one from Your Mechanic, to help you.
