That pesky Exhaust Rattle Again!!

[Len]

Had the heatshield taken off the CAT last night.

Still got the rattle/resonance!

Where are there any other heatshields that maybe causing this?
I know there is one behind the inlet manifold. Is that the only one?
Could it be a slightly lose exhaust fitting?
Dont think its blowing, sure its not!

So any suggetions please!

the rattle on mine was that thin shiny stuff that was above the pipe and seemed to run quite a distance downt he car..
not sure what bit that is?

i hit it with a hammer to keep it back in place and its seemed to stop it mostly..

is that the same as the CAT one you mentioned?

[Len]

No the CAT one is underneath the CAT itself. Thats the one i had taken off!

So there's one between the manifold and the body then. Must be a bugga to get at!

I had a Cordoba with the same mk3 16v engine for a while and the heat shield on that used to buzz a treat. That was the manifold one. Mechanic welded it in place a couple of times but said it was a nightmare and if you really were fed up with it, you may as well just get rid of it!

* wonders if we're talking about the same thing *

the bit i'm talking about runs right up the middle of the car above the exhaust.. i think its that shiny aluminium (cant be welded?) stuff you see around pipes in industrial places.. ?

[jv]

um, probably not then, i'll get my coat and be off now  :-[ 

[hardo22]

dont know if this will help,...on my mk3 there was a rattle/ buzzing caused by a missing rubber grommet on the heat shield above the back box........... it cost pennies to fix.......

[mrwotto]

My exhaust keeps rattling due the misses noit slowing down enough over speed bumps lol

[Len]

Even thin ally can be welded by a good welder with the right kit!

Yes jv i know which one ya mean. Have tried to bend that one and tighten up the nuts.
The problem is i cant recreate it at a standstill. It only happens when driving i.e. under load.
So its bloody impossible to find where its vibrating!

Thanks Overseer i'll get it up on a ramp somewhere and have a good look!

[Overseer]

i dunno if mine still does it, or that i got used to it..

rear passengers claim they can hear something..


i'm waiting for it to drop off so i can get SS run up throughout
