I still think it is a faulty clutch which from memory did not get changed in the whole gearbox change over point.....

A clutch problem would fit with the noise 'changing'.

You are right Tim, I did not change the clutch although I did fit a new friction plate. If it is the clutch I would nopt be unhappy, I know how to do that now!!!! I will keep using it and see if I can provoke it a little more.

Thank you Brian for the thought on the thrust washers. I will try that and report back.

Just reporting back ........ there is no discernible movement in the crank pulley relative to the sump casting when the clutch pedal is depressed and also there is no change in engine speed. So it is looking less likely that the crankshaft thrust washers are the culprit.

This was checked this afternoon with the help of a grandson ... I had faith that they would come in useful eventually!! We then went for a drive with said grandson holding the mobile phone to video our progress and the accompanying noise. I will get the help desk to upload the video to something where you, the cognoscenti, will instantly diagnose the problem ..... I hope. I will let you know where and when the video is available to view.

In the meantime I am contemplating rebuilding B20 driveshaft UJs and pot joints!!

The pot joint rebuild should be a nice clean "bench" job ....

Good , continued, hunting with the noise

Andy,
sorry my Penn'orth didn't help but at least it's another checked.
I shall wait with my stethoscope plugged into my ears!

With the help of the second generation helpdesk video clips have been uploaded to instagram. Find them at #Appianoise or on my account @thecern.

Please listen, diagnose and advise!! Somehow I have a feeling that it will not be that simple, but any suggestions would be very gratefully received.

Frankly dear people, I am disappointed!! Not a whisper, not a murmur!! Is no-one prepared to put their head above the parapet and offer a suggestion as to what the bloody hell this 'orrible noise might be?

Come on .......... please, what is going on in that engine?

Thankfully Andy I'm not an expert so I can say what I like and expect to be corrected!

Its not an engine noise for sure, sounds almost like dried out/aged leather rotating against something in the drivetrain, did they use leather much in the Appias construction?!... Cool...seriously the noise reminds me of the old style wooden "rattles" used by footie fans.....the driveshaft rubber coupling failed/disintegrated, if they used them in the Appia?!

Hoping the guys with the real knowledge pass by!

Frank, you have described the noise accurately. When it first started it was more like an exhaust pipe banging against the body!!

Anyway, it does seem to be in the engine or gearbox/clutch assembly as it can be provoked when stationary.

Sorry Andy,
I don't do Instagram either,

Do you by any chance have a heater? if so perhaps the fan?
As you say it can be provoked when stationary I assume that is with the engine running and by operating the clutch, is the engine moving on it's mountings and catching against something?
Is it possibly the fan assembly itself catching?
I'm also clutching at straws!

If you don't do the instagram thing, how can you get to hear it - via the facebook thing ?

Thank you for the thoughts Brian. These matters have, I think, been dealt with. There is no heater. New engine mounts made no difference, although they all three were shot, so together with a visual check I have ruled out movement of the engine. Don had suggested the fan catching, but there seems to be plenty of clearance there and no signs of damage etc on the tips of the blades.

This has been the frustrating thing, that as it initially only occurred when under way, it was not possible to get a head under the bonnet to investigate. As it has got worse I may now stand a chance, but it is not bad enough yet!! I am just hoping I can identify the problem before something breaks and it gets expensive!!

Time, as always, will tell!!

Andy,
What sort of speed to you have to be doing to hear the noise?
No doubt health and safety would have a fit, but in my youth I sat on many a front wing holding on at low speed listening for noises!
Is it possible to put it up on Axle stands and sturdy wooden blocks and run it in gear with the back wheels off the ground, with the front wheels  securely chocked? even better if you could get access to a four poster lift with the front to back rails which can support the car with the wheels off the ground and try running it in gear.

...then running it in gear against the handbrake.

The other place to test is on a rolling road.
