RE: loud noise when accelerating - 10/28/2008 3:26:16 PM    Hobbin Posts: 99 Joined: 5/1/2008 Status: offline Guys I''ve been procrastinating on posting about the EXACT same problem. I''ve been dealing with this high pitched noise for several several months, trying to figure out what it is. My CAI definitely makes a noise, but it''s not the noise I''m talking about. I would describe the CAI noise as a "whistle," where I would call this unknown noise a high pitched "squeal." Now I''ve heard loose belts squealing before, and it sounds nothing like this. Just to make sure it''s not a belt, I''ve put pressure on the belts that are visible to see if I can induce the noise or cut it out. Nothing happens. I tried to figure out how to loosen the tension on the timing belt then bringing it back to normal....but I ended up cancelling that mini-project in fear of ''messin up big time''. I don''t think it''s the timing belt anyways. What it DOES sound like is a squealing bearing. My first thought when I heard the noise was "Oh, my throwout bearing is going bad." When I found out automatics dont even have that, I lol''d @ my stupidity. No particular action will induce the squeal, except for when pressure is put on the engine. I mean, when the engine moves. When I pop it into gear from neutral, it squeals like crazy. SOmetimes worse than others. This is what made me think it was something to do with my transmission (since it sounded like a bearing, I assumed throw out bearing). After some studying and messing with it, I found that when I pop it into gear, the engine will move back a little bit, thus causing the squeal. So if it''s in neutral and not moving, I can push on the block with my hands (when not hot) and I can induce the squeal. HAF, what are some steps I can take to help me fix this problem?! **for the record, I do have a small exhaust leak between my headers and exhaust manifold. I don''t think this is the problem though, because the squeal sounds like metal against metal, not a "whistle" sound _____________________________ If you plan on being original, plan on being copied Owner of "The Battleship" NGK iridiums, Struts, Sways & tie brace, CAI, AND A NEW BATTERY +nice deck && subwoof+speakers+2amps quote: ORIGINAL: finch13 I don''t know what Hobbin is smoki (in reply to stevenb17) Post #: 8

To pin point where the noise is coming from, once you know where,then you go from there. _____________________________ >>Click here to see my Accord<< (in reply to stevenb17) Post #: 11

No other part,bearing,belt would make the type of noise you are describing at and only at a particular rpm. (in reply to falkore24) Post #: 13
