my exhaust has developed a slight rattle..
i'm sure its just something thats worked its way loose a bit.. (have a feeling it may have worked its way loose or been caused when the new starter was fitted to my car a little while ago).
i dont notice it all the time, it appears to be mostly when the car is at low revs, often when reversing. however it doesnt do it all the time.
how can i track where its coming from so i can work out a solution?
(yes a nice powerflow would be a nice option... but only if its *really* needed)
-
best way to check if it is your exhaust is to get under your car, it might also be some thing else under there, it was my heat shield on my old car.
-
I did take a bit of a look under. I can't really see anything obviously wrong, but i'm not sure what i'm looking for.
-
Get the car on stands, start the engine , get a mate to rev it while you look underneath it.
-
guess i need some stands.. oh and a mate that doesnt only leave the house to go to the pub.. guess my dad'll do... lol

Just something to check for, shortly after I got mine it developed a rattle that really pissed me off. Basically it hit a harmonic when it was idling just after you started it. Mine turned out to be the heat sheild over the back box that had come loose on one side and was resting on the back box. Pushed it back in place (the clip just grips on the thread of a bolt stud). It's been silent ever since. Have heard from others with mk3s and mk2s that it's pretty common.
Hope this helps! :)

Mine had the rattle when I first bought it but that was cured with some big jubilee clips. Unfortunately the rattle has returned and it appears to be from the metal/heat shield that is attached to the underside of the car as opposed to the Cat.....dont know how to stop this one????? Also have a knocking from the exhaust when accelerating but I think the rubbers need replacing as they are flexing too much and the bolts on the o-clamps are hitting the support bracket 3/4 of the way down the car?? Any ideas on cures for either probs ???
-
it's usually a busted weld on a heat shield somewhere, happened to me before and i just ripped the shield off, problem solved ;D (just dont park it on any grass..)
-
ok... managed to get it up on ramps saturday morning.
the heatshield on the exhaust, and the actual exhaust itself are fine.
the problem appears to be what i assume is another heatshield that sits up above the exhaust on the floor pan itself for a lot of the length of the car. think its made of think aluminium, we gave it a bit of a bash with a hammer, and it appeared to solve it for a lil bit, but now its started doing it again. :(
-
Didnt read this until after i posted mine in Garage section.
Sounds like we got similar problems. I hear mine between 2500 and 3000 revs.
With more than one heatshield this is gonna be fun to sort out! Not!
-
i had this problem when i took a potential customer for a test drive when i was selling my mk2. Fortunately my old man said it was only the fixing clips that had worked loose. If you can try and apply some kind of sealant before you sqeeze the clips back on to stop it working loose easily again.
hope that helps mate.
-
I've got exactly the same prob as Overseer and Len, originally it was the heat shield below the cat that had worked loose. I fixed that with big jubilee clips, but now the noise I think is the shield body side of the cat. Need to get underneath and get a mate to help, but nothing obvious to stop it as the metal is so thin.....also happens at 2-3000rpm.....help please ???
-
ditto! I have had the front heat sheilf fitted back twice - now it's rattling again - but somewhere else as I checked the front shield last weekend!
Not sure I can be ar5sed to sort it though.
"Turn the stereo up" [as my g/f would say]!
Cheers

Yep...the stereo is the current cure for the problem!! Well annoying though as sounds rough
-
easyfix solution - a few large blobs of sealant/mastic under the heatshield will do!
-
Thought i'd resurrect this one.
Had chance to have a good look under my car Sat morn. (change drive belt) up on garage ramps.
Front heat shield o.k.
The one thats resonating now is the one under the CAT - mine seems to have developed two cracks one either side of the front fixing point.
So cant really see an easy solution to it.
1. Turn the volume up.
2. Get a new CAT (very drastic/expensive)
3. Put up with it and play making it sing!
4. Rip the fu*kin thing off!!!!!
Number 4 is favourite atm - but havin fun when i'm in the mood to play with the revs and see how many different sounds i can get from it!
;D ::)
