CanadaCraig Posted June 19, 2004 Share Posted June 19, 2004 I Guys!! :) Apparently - my LS has a warped flange - which is a 'thing' between the exhaust pipe and manifold - so I believe. If you know what I'm talking about - do you also know if that's an expensive part? I can't seem to find 'it' anywhere. [unless it goes by some other name - OR I just haven't been looking in the right places] It's that 'warp' that has been causing a lot annoying exhaust rattles. It became warped [apparently] when someone put the exhaust system back onto the car after having balanced the driveline. Craig!! :) Quote Link to comment Share on other sites More sharing options...
99lsguy Posted June 19, 2004 Share Posted June 19, 2004 Are you sure a bolt hasn't just come loose................when something ratttles, its usually loose. Like something came apart from a bracket or similar??? Quote Link to comment Share on other sites More sharing options...
CanadaCraig Posted June 19, 2004 Author Share Posted June 19, 2004 Hi 99lsguy!! :) No - it's not a loose bolt. [unfortunately] The Lexus service guys have told me it's a warped flange. They tried to make up for that warp by using silicon. It helped - but it still rattles when starting the car a few minutes after its' been running. [in other words - when it's warm] I was given the impression that a new flange is expensive - but I never enquired as to HOW expensive. [i probably didn't want to know - at the time] I highly suspect that it's that warp that has been causing the other two problems - a vibrating gas pedal and shifter. [at least I hope so] Now... if that's fixed [as in 'replaced'] AND the gas is cleaned up [it's still dirty] I just might end up liking my LS after all. [oh yeah - and put on new STRUTS!!] Thanks, Craig!! :) Quote Link to comment Share on other sites More sharing options...
99lsguy Posted June 19, 2004 Share Posted June 19, 2004 Craig, Gotcha dude!!! I'll check into it and get back to you tomorrow.........!!!!!!111 Quote Link to comment Share on other sites More sharing options...
cnacne Posted June 20, 2004 Share Posted June 20, 2004 If you can do it yourself, maybe try buying another gasket. Use the two of them together, they may stop the rattle. Quote Link to comment Share on other sites More sharing options...

Craig, I think this could be a good idea............ Is it anywhere on this diagram? comp.pdf Quote Link to comment Share on other sites More sharing options...
CanadaCraig Posted June 21, 2004 Author Share Posted June 21, 2004 Hi cnacne!! :) Thanks!!! That IS a good idea - but I can't help wonder why the guys at the Lexus place didn't do that. They just used a bunch of silicon. If they're not willing to replace the flange [which I think SHOULD be done] than I'll mention your two-gasket idea. I just want the rattling to STOP!! Hi 99lsguy!! :) Thanks for the diagram. Although I'm not sure - I think the flange causing the problem just might be part of one of catalytic converters. Maybe that's why I was 'warned' about it being an expensive part. Hmm... I better go back in - again - and get this dealt with - once and for all. I also have to have the fuel problem dealt with. You can read more about that in my 'dirty fuel?' message. Thanks again, Craig!! :( Quote Link to comment Share on other sites More sharing options...
