ibr_adam09 Posted December 22, 2010 Share Posted December 22, 2010 Not 2k to 3k, exactly at 2k rpm I hear a rattle in every gear shift. I'm not really concerned about it, or should I be ? It's similar to the infamous dash rattle most of use have. Scenario: *engine revving * 1k > 1.3k > 1.7k > 2.0 [rattle!] > 2.3k [no rattle] > 3k > shift and repeat. I checked the heat shields and they're bolted down pretty tight. 100k, catless uppipe, but stock really Edit: Came back again, but this time I'm a bit more than stock, lol Link to comment Share on other sites More sharing options...

ibr_adam09 Posted December 23, 2010 Author Share Posted December 23, 2010 I'll try to get a video. I can hear in towards the front / under the dash area (anywhere between back of the radio to cupholder area) ITS EVERY TIME THE RPM HITS 2K, never misses a beat It's only audible for about 1 second I thought it would be that 14mm bolt that holds the downpipe to transmission coming loose, but that was on tight as well Link to comment Share on other sites More sharing options...
bmx045 Posted December 23, 2010 Share Posted December 23, 2010 is the engine under heavy load? Link to comment Share on other sites More sharing options...
Scooby Fan Posted December 23, 2010 Share Posted December 23, 2010 I had the exact same situation with my '02 Impreza RS...it turned out to be the springs in the clutch plate...they were just a bit loose and rattled at exactly 2200 rpm....both on acceleration and deceleration....SOC put in a new plate on warranty and that was the end of the problem....Maybe???

Dutch Eagle Posted December 28, 2010 Share Posted December 28, 2010 Ah, I missed this one: ITS EVERY TIME THE RPM HITS 2K, never misses a beat It's only audible for about 1 second Have you checked the springs were the bolts go through, on the joint between downpipe and midsection? I had the same rattle once, and one of the two bolts had to be tightend. Link to comment Share on other sites More sharing options...
imstillatwork Posted December 30, 2010 Share Posted December 30, 2010 Ah, I missed this one: Have you checked the springs were the bolts go through, on the joint between downpipe and midsection? I had the same rattle once, and one of the two bolts had to be tightend. dang good idea. A rattle/noise in a very narrow rpm range during accel AND decel is often the resonance of a loose part. Since the issue happens at such low rpms, have a friend hold the motor at that speed until you can hear it, while you listen in the engine bay for the noise and try to locate it.

ibr_adam09 Posted January 20, 2012 Author Share Posted January 20, 2012 Bump. Sound came back. I'd assume this is loose bolt somewhere, but will be tough to find. Link to comment Share on other sites More sharing options...
