Yes the rod bearing shells were done a while back....

One of mine is making almost the exact same noise right now. I'm 99% sure it's either the clutch release/throw out bearing or broken pressure plate. The noise disappears if a gear is engaged, only does it in neutral or at standstill in gear (clutch disengaged).

I'm pulling the gearbox this weekend.

I had that same prob on my (this car) SMG, 3 years back. Was different noise Id say. At first I thought it was the power steering pump, was a growly rotary sort of noise. The clutch release bearing had failed.

News...
The job is moving slowly, injured finger!
-vanos is rebuilt and timed up using digital angle gauge (v accurate) as photo.
-checked the spark plugs to rule running issues out of play -all identical/perfect colour.
-I cut open the oil filter, nothing much in it at all (5.5k miles).
-I bought a new bucket, emptied the oil into it, waited 2 days for things to settle then looked at the dregs, outcome: virtually none (but some) metal, not enough to consider a rod bearing failure, unless as stated earlier, I've caught it & stopped the engine seconds after a spun shell.

I'm hoping its not a rod bearing and so far no evidence that it is, which is good of course, however instinct tell me it is.

More news asap.

some metal isn't a good sign usually..I was hoping it would be a bad follower or a spit shim or something minor, maybe check those? Maybe u missed it

Its the clutch!
-pivot pin looks ok
-attrition marks where the clutch release arm was hitting the clutch
-release bearing burnished on the outside, not the pressure face/land
Root cause,,,,,-> a bit unclear.
New everything in there should fix it

It was the clutch limit stop, -fractured after 40k miles.
New flywheel has killed off the M clunk ! I'm pleased.

Progressively eliminated possible faults until best option was to drop out the gearbox. Only when out was the fault clearly visible.
