[Healeys] Dash Area Noise

[banjojohn]

Just another thought.  I fought an irritating noise seemingly coming from under the dash for quite a while before realizing it was the hood (bonnet) bouncing up and down at the rear passenger side corner. It was bouncing against the hood opening drip lip.  There are a couple rubber bumpers in the drip lip channel but they did not  do the job.  I used self adhesive foam weather strio and lined the entire drip lip.  Problem solved, for my car anyway.  I never noticed the bouncing hood because the rear view mirror blocked my view of that corner of the hood.Obviously its hard to say if your problem is the same, but I thought I'd pass it onJohn O'Brien'65 BJ8 (Madelyn)'61 Bugeye (Lucy)Sent from my Sprint Samsung Galaxy S7.

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----- Original Message -----From: Bob Spidell <bspidell at comcast.net>To: healeys at autox.team.netSent: Thu, 18 Jul 2019 08:52:16 -0600 (MDT)Subject: Re: [Healeys] Dash Area NoiseEarl,Is this Moss# 858-385 (#44 on page 118 of the latest catalog0?  You're describing the problem I have.BobOn 7/17/2019 11:22 PM, Earl Kagna wrote: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.

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.
