vibrating/rattle at 3000 rpm

[DAVES_GT3]

while at the oxford meeting i managed to pick up a mad vibrating noise.

sounds like loose baffels in the exhaust but it only does it when driving around 3000rpm. if i rev it stationary i cant hear it.

it has got a larini twin exit ehaust system on. unsure if that would have baffels in it?

mentioned it to dermot in oxford and suggested the heat sheild attached to the back of the engine bay by the turbo may be the culprit.

it doesnt seem loose.

just wondered if anyonme had had any similar thing happen?

thanks

I had a horrible rattle / vibrating noise at 3000, but it was the EBPV - which you don't have on the GT3.

I would say that it'd have to be something connected to the Exhaust system.

i thought that but it seems strange that it wont do it while stationary. would have thought revving up would have given the fault. therefore difficult to locate where its coming from.

will have to lock the missus in the boot and go for a drive! hmm tempting!

The crazy thing is that I have the same rattling, except i hear mine as long as I am driving. Then again, the engine and exhaust noise usually drowns it out after a while. I can't hear it, but I know it's still there...

this is loud. patrick could clearly hear it when he was driving behind me in oxford on the run. quite embarrasing when you have a sweet note coming from the exhaust. stands out like a sore thumb

Could it be the wastegate? you could check and see if you can feel the arm rattling with the engine cover off and someone holding a steady 3000rpm for you.

Has anyone mentioned 'disintegrating catalyst' yet?

Failing that... drive faster

[lotus4s]

Could be loose heat shields, exhaust hanger mounts, exhaust tips and or as already mentioned the EBPV to name a few...

Also when looking at the heat shields (usually the ones around the left motor mount) look for two that may not necessarily be loose but vibrating together or against the manifold at certain RPM's.

Cheers,

Hi Dave,

Just remembered, was behind you for most of the run and i heard it too.

Thought it was mine at first but could only hear it when i got close to you.

Sorry i forgot about this, your description of the noise is spot on BTW.

PS,

I only noticed it, as it was totally different noise to my own rattles!

it is a sad life of the Esprit owner when we now compare rattles or recognise our cars by the particular rattle.

Mine is no exception with many rattles, knocks, the occasional grind but no bangs lately... not sure if thats a good sign...

[DAVES_GT3]

Thanks for the input guys!

Think it will be a difficult one to find but going to give it a go when i have a spare pair of hands. Needs to be sorted so i will post a reply as soon as ive located the problem.

Cheers

i had an exhaust rattle that suddenly went away mysteriously. i was actually worried for a few weeks. the noise is back now and it's chitty chitty bang bang all over again.

[DAVES_GT3]

Phew!!

All done. one of the exhaust brackets had parted from a welded joint and therefore vibrating against it.

Just shows there can be small problems and easy fix's on the esprit as well as big ones!

cheers everyone
