Hey everyone. I have searched the forum and haven't been able to find anything yet that describes what my car is doing. A couple weeks ago I had the power steering rack and pinion replaced because the old one completely broke. When I picked my car up I noticed that the engine sounded louder when I started the car. Almost like I had cotton in my ears before and the cotton was removed so I could hear things louder. It was louder on the driver's side. Then when I drove it away from the mechanic I noticed the engine was making a loud buzzing sound from the driver's side. Definitely coming from engine compartment. To me it sounds like the exhaust sound kids put on their Honda's these days. It only makes the sound with hard acceleration, like pedal to the metal, and it fades out after a few seconds of acceleration. I noticed it's usually between 2000-3000 rpms. I took it to a different mechanic and he rode around the block with me and heard the noise. He said it sounded like an air intake issue, like something was loose or not connected. He looked in the engine and didn't see anything disconnected so I made an appt. When I went to pick my car up they told me that there is an "air box" under/near the bumper on the driver's side of the engine and that when I accelerate hard it is taking in more air which is what is making the noise. I told them it wasn't making this noise before I took it to get my power steering fixed. They said they didn't see anything wrong with the power steering and that there wasn't anything structurally wrong with my car. My question is, does the air box suddenly start making the car sound louder after being fine for 7 years? My car is a 2006. I don't feel any difference in the way my car is driving, it is just louder now. Sorry for the long post. I have a recording of the sound but the file type won't upload. Thanks for any help!

Plastic doesn't last forever, there could be a crack or leak in the intake all the way down to the resonator box which is impossible to see from just popping the hood.

He initially looked under the hood and when he didn't see anything he said he would need to put it on the lift. So I made an appt and they looked under the car as well. Not sure if that helps them see anything better. But what I really want to know is, if there is a crack or what not wrong with the intake, is that going to cause a problem with car performance or mess up my engine, or is it just an annoyance that my car will be louder and that's all?

Hard to say. Personally, I doubt it, but I wouldn't put my name on it. I would be more worried about actually finding the source of the noise first.

What about exhaust? If they had to take your test pipe/downpipe/ pipe between headers and cat down to make room to get the rack out, they may have reused an old exhaust gasket or not sealed it properly and you're hearing a leak?

Also, can you pull your car next to a wall and take a video from your driver's window (down and up) and if you can while driving so we can try to hear what you're talking about?
