UltraFlynn Posted January 31, 2006 Share Posted January 31, 2006 Ever since I first got my Supra it's had an annoying rattle. I even noticed on the original test drive and figured it would be something simple to put right. I've had a garage look for it and they couldn't see anything obvious. (It was only a quick check though so I don't blame the garage for not finding it) But now is the time to try and find out exactly what it causing this hugely irritating and embarrassing rattle. What I'd like to do is to describe the symptoms and seek suggestions as to how I can go about checking that item. Hopefully then I can narrow down the issue and get it sorted. (Bare in mind that I'm pretty poor around cars. I have little skills with the spanners ....) Here's the symptoms: - 1. It doesn't do it when cold. Only once the cars been driven for 10 minutes plus does this rattle start. 2. It sounds like a thin bit of metal vibrating against something. 3. It continues to rattle when not moving. 4. (To my ears) it sounds like it's coming from the passenger side of the engine bay. 5. Turning off the air-con, or putting the car in neutral (i.e. changing the engine revs) can make it go away. It gets worse at certain engine rpms but it's definitely something external to the engine. 6. It honestly sounds like something is loose ... but what? All ideas are sought and I'll try to get outside and do some diagnosis as I receive ideas. Please help me get rid of this. It's embarrassing pulling up to some traffic lights in the worlds coolest car and all you (and everyone else) can hear is "rattle, rattle, rattle ...".

Daston Posted January 31, 2006 Share Posted January 31, 2006 Not sure but there may be a heat sheild or somthing down there that is slightly loose Quote Link to comment Share on other sites More sharing options...
TLicense Posted January 31, 2006 Share Posted January 31, 2006 Something around the exhaust? Do you have full decat pipes? The catalytic convertor can sometimes break free from the bit that holds it to the actual pipe and can rattle. (Had this on my GT- Four, but not heard of it on a Supra before) Quote Link to comment Share on other sites More sharing options...
suprattgaz Posted January 31, 2006 Share Posted January 31, 2006 Heat shield on exhaust or bracket holding cat to gear box can snap and rattle- had that happen before! Quote Link to comment Share on other sites More sharing options...
UltraFlynn Posted February 1, 2006 Author Share Posted February 1, 2006 I does sound like a heat shield to be honest with you. I guess I need the one on the exhaust. Are there any more? And what's the easiest way to check them? Quote Link to comment Share on other sites More sharing options...
Rob Posted February 2, 2006 Share Posted February 2, 2006 If it is the exhaust heat sheild, it'll be the mid-pipe which is completly wrapped in a metal carcass, the front bit of this rattles and can be seen by laying alongside the car. It's where the pipe bends up into the engine bay. I put a big F-off jubille clip round mine to squeeze it to the pipe. It worked. Quote Link to comment Share on other sites More sharing options...

Scooter Posted July 8, 2006 Share Posted July 8, 2006 There are exhaust shields that are bolted to the car, as well as those that surround the Cats. The cat ones, you might be able to check by holding a broom handle directly to the exhaust and seeing if the rattle goes/or you can feel the vibration. To check the shields attached to the car (normally situated above the hot bits ie cats and the 3 stock silencer positions) you will need to get underneath it..........

Jake Posted July 9, 2006 Share Posted July 9, 2006 Turbo heat shield? They rust like the ace of spades around the bolt holes. But that's driver's side.... What could it be on the passenger side? Fuel filter shield? Dipstick bracket? (Gearbox or engine) Gearbox to DP/MP joint bracket? Fuck knows, could be anything! Quote Link to comment Share on other sites More sharing options...
Pete Posted July 9, 2006 Share Posted July 9, 2006 I had a rattle. Turned out to be my brain cell. Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted July 9, 2006 Share Posted July 9, 2006 Get the car on a ramp and hit the exhaust with the ball of your fist, hit it all the way along the exhaust until you hear the rattle, you'll be able to locate it then. If you don;t hear it, its not the exhaust. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 9, 2006 Share Posted July 9, 2006 I say its exhaust if it doesnt do it when its cold. Im like you I hate little rattles and squeaks so I hope you sort it Quote Link to comment Share on other sites More sharing options...
