[Healeys] Dash Area Noise

[WILLIAM B LAWRENCE]

I think the easiest access to that part is to remove the fender... If you call hat easy. Regretting that I didn't Loctite those screws...

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 you

Earl,

Is this Moss# 858-385 (#44 on page 118 of the latest catalog0?
You're describing the problem I have.

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.

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 !

rg.
