[Healeys] Dash Area Noise

[Roger Grace]

Thanks to Earl, Bob and others for good suggestions and ideas.
However after lot more poking around little progress and still cant replicate the noise.One thing is that if the car has stood in the coolness of overnight it takes about 10 mins for it to be back with a vengance. The irritating thing is that it is random and a definitive pattern still elludes me. Noise seems to be in the vicinity of the volt regulator box.One of these days will remove the passenger air vent hose and try to access the plate Earl referred to.Think that this could be the culprit.Thank yourg

Roger: This reminds me of a similar situation that I had many
 years ago on my BJ8 – a ‘thunk’ sound from the left side of
 the dash area (or so I thought) on certain bumps but not
 others. Drove me nuts trying to find it - literally for
 years.  Finally found it when the car was torn down in
 conjunction with the total restoration. There are 2 plates – one on each side of the car – called
 wing support brackets in the body manual (plate BC 2) - that
 tie the assembled wing / shroud flange to the top of the
 inner wheel arch.  The manual is not very clear on this
 thing. When dismantling this part of the body, we found the pair
 of bolt / nut assemblies totally missing and clear evidence
 that this was the source of the ‘thunk’.  But it sure
 sounded like it was coming from the dash or bonnet. Your problem just might be that these bolts are there but
 loose, which could conceivably cause a creak type of sound
 that seems to be from the dash area.  Try pressing down on
 the right side fender / shroud close to the centre of the
 wheel cut out and maybe fore and aft a bit to see if you can
 produce a similar sound.  The bad news is that these things
 are a real pain to get to on an assembled car – they are
 almost impossible to see, let alone service as they are up
 high and behind the air hoses on both sides, and can’t be
 accessed from the wheel arch because of the inner fender
 position. If all else fails, it’s worth a try.  Let us know. Earl Kagna

Am about fit to be tied ! 

Have been struggling with a new intermittant noise for
 about a month now. 

Seems to eminate in the dash area above left side of
 glove box, 

A creak rather than a clunk. 

So what have I done. 

Tightened everything in that area - starter mounts,
 clecked bell housing, checked brake booster mounts,
 jammed the air vents solid, removed center console and
 still no improvement.Tightened windshield side mounts
 doors checked. 

Was convinced was something to do with the heater
 controls - spent most of one weekend removing and
 replacing it more securely (what a pia job !). 

The noise is not tied to road or engine speed, but worse
 when going over uneven surface, even very slowly. Also
 thought was worse after car was warm so switched heater
 valve off. 

Thought had breakthrough as got a lot better with top up
 that pointed to windshield mounts. But no after a few
 days back as before. Actually sounds like expansion type
 noise. 

It even occasionally does one or 2 creaks when car
 stops. 

In last 2 years had windshield replaced so wonder if
 could be a problem there ? 

Cannot recreate the noise with all manner of pushing and
 pulling of dash or glovebox or airvents and windshield
 in that area. 

Tried jacking the rear end up in case was chassis but no
 change, 

What is maddening is that there are times when for
 aboiut 20 mins of driving it is gone.... 

Ideas please !
