nuclrxn Posted November 14, 2011 Share Posted November 14, 2011 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.

SurlyOldManMN Posted November 14, 2011 Share Posted November 14, 2011 Could well be loose IC -> TB hose and/or folded gaskets. Pull the intercooler. I got the "balloon whine/honk" when the gaskets started to fold over and also to a lesser extent when the hose was wiggling loose. Link to comment Share on other sites More sharing options...
01rs25 Posted November 14, 2011 Share Posted November 14, 2011 I would happen to agree. Sounds like a loose charge pipe somewheres. With only 2700 miles I would take it back to the dealer and have them solve the issue. Slammed more than your girlfriend. Link to comment Share on other sites More sharing options...
nuclrxn Posted November 14, 2011 Author Share Posted November 14, 2011 Thanks, guys. Also, the noise I hear when I don't hear the "horn" is a deep breathing noise; kinda like I have a CAI installed. I'll upload a video. Link to comment Share on other sites More sharing options...
SurlyOldManMN Posted November 15, 2011 Share Posted November 15, 2011 Yup, sounds about right. Link to comment Share on other sites More sharing options...
Subie2012 Posted November 17, 2011 Share Posted November 17, 2011 I do have the same issues...not always though..on highway.....I have 1800 miles on it.. Link to comment Share on other sites More sharing options...
nuclrxn Posted September 10, 2012 Author Share Posted September 10, 2012 As a follow-up, I'm at 16,000 miles now and the noise is non-existent. The dealer reseated the intercooler and gaskets, as suggested by SurlyOldManMN, at around 3,000 miles and that did the trick. Thanks, fellas!

nuclrxn Posted December 2, 2012 Author Share Posted December 2, 2012 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. Link to comment Share on other sites More sharing options...
SurlyOldManMN Posted December 2, 2012 Share Posted December 2, 2012 You need to REMOVE those gaskets, not reseat them. $10 says you have the exact same issue you had before. Link to comment Share on other sites More sharing options...
SurlyOldManMN Posted December 2, 2012 Share Posted December 2, 2012 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.

I'll be doing this tonight. Thanks for the tip, SurlyOldManMN. F the dealer this time around. Link to comment Share on other sites More sharing options...
nuclrxn Posted December 4, 2012 Author Share Posted December 4, 2012 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. 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. Link to comment Share on other sites More sharing options...
