The engine still runs like normal, and the noise stops after sitting at idle for a couple minutes. I tracked it down to the part in the center of the following picture: When I stick my hand next to it, I feel air blowing out the sides of the "lid", and the noise subsides when I push down on the top. I took a quick video to show this and the noise: http://www.youtube.com/watch?v=5nkN8wYPpVY Any ideas what the problem might be, and is it safe to drive the car in the meantime? __________________ -Kenny | | | 05-05-2009, 11:49 PM | #2 | Senior Member Join Date: Sep 2006 Location: Wisconsin Posts: 1,895 | Secondary airpump. cooljess76 wrote how to fix it somewhere on this site. I seem to remember the fix was to grind off the rivets and bolt down the lid. __________________ ... ʎɐqǝ uo pɹɐoqʎǝʞ ɐ ʎnq ı ǝɯıʇ ʇsɐן ǝɥʇ sı sıɥʇ | | | 05-05-2009, 11:55 PM | #3 | Senior Member Join Date: Aug 2005 Location: Melbourne, Fl/Athens, AL Posts: 393 | That seems kinda... iffy. If it's an airpump, I guess it's part of the emissions system? Does anybody know what would cause it to randomly start doing this? __________________ -Kenny | | | 05-12-2009, 08:26 PM | #4 | Senior Member Join Date: Sep 2006 Location: Wisconsin Posts: 1,895 | Any progress? __________________ ... ʎɐqǝ uo pɹɐoqʎǝʞ ɐ ʎnq ı ǝɯıʇ ʇsɐן ǝɥʇ sı sıɥʇ | | | 05-12-2009, 08:39 PM | #5 | NOBODY F's with the Jesus Join Date: Oct 2006 Location: Ventura California Posts: 7,824 | The secondary air pump is basically composed of a series of plates that are held together by 6 aluminum rivets to make up the body of the actual pump. The rivets tend to break, allowing the plates to separate and leak air. The reason that you only hear it momentairily after startup is because it only runs for about 30 seconds after the car has been started on a cold engine. You can easily fix the problem by first removing the secondary air pump, removing the broken rivets and possibly drilling out the others. Then replace them with machine screws and locknuts. This should eliminate any problems and extinguish your CEL. Depending on how long you've known the noise to be there, you may consider taking the pump apart and cleaning the internals with brake cleaner. It's not absolutely necessary, but just a suggestion. Also, while you're working in that area, you may want to replace the ribbed rubber boot between the MAF and the ASC valve as it's known to crack and give you misfire codes as well as trigger a CEL. Good Luck, sorry I came in so late. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
