Hi all. I've got a knocking/clacking noise just start up in my 86 Mayfair that sounds like its coming from behind the steering column/in the engine bay after an hours drive today. Its only there when the car is moving (not idling) and increases and decreases in speed in time with the car. It went through a period of doing it a few months back but stopped of its own accord??? Noise doesn't change with braking/cornering/over bumps Any ideas what this could be as im clueless?
Cheers
Jamie

Check the top engine steady between the cylinder head and the bulkhead just under the clutch master cylinder.

Physically grab the engine (when its cooled down and off), and give it a shove. If it moves a lot, the bushes in the steady are goosed.

Easy to change and cheap.

Does it get more rapid as the refs go up? Or does it happen on acceleration and decceleration?

It happens on acceleration, cruising and deceleration but not while the car is stationary and revving. The noise sounds like putting a piece of paper in a spinning fan if that makes sense!!

Pot joint or pot joint gator clip ?

Thanks. Tried this but seems pretty tight, only very minimal movement.

Whats this? sorry my knowledge is very limited

Look underneath the car, follow the drive shaft from the wheel, big joint just before it goes into the gearbox. Also, if they're still fitted, check you dont have anything stuck in between the brake disk an it's dust cover.

You said it...fan to shroud

Awesome thanks!

Hi folks, still cannot locate the source of this knocking sound!! I've attempted to record the sound but apologies for the very shaky video. Anyone have any ideas?

Cheeky bump 😃. My main worry is that its something suspension/steering wise and that something is suddenly going to go bang whilst driving.

[New game mini]

Still not managed to sort 😞 i've checked:

*Engine steadies
*Exhaust
*Crap behind dust covers on brakes
*Pretty sure it's not fan to shroud (noise in the wrong area)
Looks like its a trip to the garage 😞
My mate said it could be something in the speedo, does that sound plausible?

Wow wish I could help that sounds expensive but to solid a noise for the speedo to me

[New game mini]

For anyone reading in the future the noise waaaassss.........THE SPEEDO CABLE!! Speedo started dancing around today so I unhooked the cable and no noise! Hallelujha!! Just gotta fit a new one now which i believe is a bugger 😱😱
Thanks for all the help.
