2012 Legacy 2.5GT - Hearing Strange Engine Noise

Not sure what this noise is, but maybe the experts do. When the car is warmed up, if I accelerate past 2500 RPMs, in any gear, I hear a horn-like noise from the engine. Check it out.

Thoughts? :confused: My car only has 2700 miles on it.

btw, you can do this yourself in 15 minutes or less. I can do it in 5-10 minutes using nothing more than a socket wrench and my ham hands comprised entirely of thumbs. Just make sure you note the position of the IC->TB coupler before you pull everything apart. It's annoying to find the right angle and you won't know until it's almost completely back together.

Well, after being absent for so many miles and months, the horn noise decided to come back. Boo. I'm at 19,800 miles. WTH.

 

Have the dealers replace those gaskets. That's what warranty is for :)

I'll be doing this tonight. Thanks for the tip, SurlyOldManMN. F the dealer this time around.

SurlyOldManMN was right. Took less than 10 minutes to do this; 15 actually because I wanted to clean out some leaves and junk. Besides, it's very satisfying to take stuff out of the car. :rolleyes:

 

The rubber gasket is really soft and pliable, so it's no wonder it folds in on itself. Here's a shot of the engine bay with the IC and hose gasket taken out.

 

Sound issue resolved! Thanks, guys.
