Save a sound clip on your computer, go to 'GO ADVANCED' under the quick reply box at the bottom and then the 2nd option down the page will be 'MANAGE ATACHMENTS' up load your sound clip and it should* be in the reply!

Is you car a 3B? dizzy rattle?

[Robatron]

I have the same rattle and it either sounds like a heatshield vibrating or the dizzy gear. If you open the bonnet and listen over the top of the engine it sounds like its coming from the top of the engine but I am pretty certain its nothing serious....just slightly annoying.

yer, thanks mate thats the noise i think u r right........... seems its coming from the top as if from the pleneum chamber ........... the dizzy noise what would cause that ? i have put the 2 7a cams on last week ..............................is this a poss?

[prking53]

it may be guilty?

just had a earol , at that dizzy u guys may right .............question is the cam mesh for the dizz the same as the 3b?......................:

Well I am not completely sure of the sound but I know that it is nothing serious. I can hear it by revving it to about 2k rpm and holding it or by revving it high and leting off the throttle.

If it is the dizzy making the noise, it will just be the gear which you can replace for a metal one off of ebay but the hardest part is getting to the dizzy and the gear to replace it.

I have been meaning to replace mine but I want a good enough reason to replace it first.

get dizzy off the 20v

yer i tried last year to change the cog replace with the brass one ... but u have to strip half the engine off..................... there must be an easier way ?????? anyone

You just need to remove the dizzy... you don't need to remove any of the engine at all (although, if you can be bothered to remove the IM it helps...
also removing the ISV helps a little.... Its tight, and a right pain, but its not impossible...!!!
Its easier if the dizzy has been off before, as the tamper cover on the nut will have been removed...
search for dizzy removal, and lots will pop up...

I was thinking cam chain even before you mentioned changing the cams to 7A. Is the cam chain tight enough? Is there a tensioner or anti-rattle plate that you left off?

[prking53]

i didnt see one ,,..................has it got these ?.....................the chain is good the noise seems ton be coming at the back of the lump......near the dizzy

I've had a search for dizzy removal but it doesn't seem to return too much.
