On Christmas eve, went into town and there was a slight rattly noise coming from the engine bay area. To be honest at first I thought it was a loose heatshield from the cat area. It suddenly got louder as I reached town, 2 miles later. Pulled over to hear this:
Is it a horrific meltdown of the gearbox internals (that's what it sounds like)? Or is it anything to do with the clutch assembly?
Additional clues with which to work out an answer:
-Highly likely to be the original clutch, on 142,000 miles.
-Selecting gears is still possible but is very notchy and 3rd *almost* crunches.
-The clutch does not slip.
-Cluch pedal has been stiff for ages.
-I've had low-level clutch judder for ages when setting off.
-When stationary, in neutral and with the clutch engaged, the noise is apparent.
-When stationary, in neutral and the clutch is disengaged the noise stops.
-When driving in any gear, clutch engaged, the noise is apparent.
-When coasting with the clutch disengaged the noise is still apparent. Drive shafts are turning the diff/gears - is it therefore gear/cog realed?
I'm braced for an expensive repair, do your worst
