leic_1 0 Posted April 11, 2011 Share Posted April 11, 2011 hi guys,I bought a 2001 t sport last month and have noticed an unusual noise in a certain band in the rev range. When I take my foot off the gas and let the engine rpm decrease through 2500 to 2000rpm there is a buzzing noise, that sounds like its coming from the exhaust, but not sure. When I stay at constant speed in that rev range there is no sound, or maybe a buz for a split second wvery now and then. When I accelerate through the same range it makes the noise but for a smaler time and no where near as loud. It does not make this noise at any other time!I only noticed the noise after owning it a few days, didn't hear it on test drive but maybe kept it in higher revs. Now i own it trying to convserve the juice for when I want to have some fun (like the recent glorious weekend!). Does anyone have any thoughts? Should I get it checked out?cheers for any help you can offer. Quote Link to post Share on other sites

edwardio 5 Posted April 20, 2012 Share Posted April 20, 2012 It might & I say might, be the divider plate in the downpipe. These can fail (break loose of its welds) and then rattle around, as mine went. Without a video or seeing the car, I'm only guessing. Quote Link to post Share on other sites

paul t sport 0 Posted May 4, 2012 Share Posted May 4, 2012 i had exactly same problem with my 54 plate t sport after a major engine rebuild, took it back to a mechanic ( friend of the guy who did the original work) turned out to be a loose exhaust manifold heat shield, straightforward fix noise now completely gone replaced by the real sound of a sweet vvtli working properly!
