VIN and engine number would be useful.

Could be anything - more likely a bit of everything. Bring it to the
London Area Meeting this Thursday evening - Crooked Chimney, on the road
between A1M J4 and Wheathampstead.

Usually brake backing plate or one of the heatshields. Sometimes even
worn carrier guide pins. Propshaft tends to thump more than rattle.
Did you know there's a grease nipple on the UJ?

Yeah, it does sometimes. The after-run pump circuitry looks at time as well as
temperature. The injector cooling fan just runs on the thermoswitch
above the exhaust manifold.

If the clutch hasn't been done yet, it's about time.

Changing the oil might help. At least you'd be able to poke a magnet
in and see if there's anything floating about. Don't forget to make sure
you can open the filler before opening the drain.
