strange noise

[adam b]

Having a strange vibration or resonance when the engine gets hot. Thought it was PAS pump but it's not, then thought it might be the ally crank aux pulley coming loose. Again doesn't seem to be it. Can hear it loudly in the cabin but hardly at all in the engine bay. Very strange. 

Linked to revs (you hear it as engine revs fall) and nothing to do with transmission

Got a video at all?

Will try to do one later. I've bolt checked everything, just wondering if it's clutch related as the bearing seems to be noisy (it's weeks old annoyingly).

I guess the sprint tomorrow and/or a track day next week will answer my concerns about it. Waiting for the bang as usual

Noise go when you put pressure on the clutch pedal at all or go when clutch fully depressed?

[adam b]

Does it whatever happens with the clutch. Except it hasn't today. Drove it like a complete arse as well, properly hard for a few miles (as fast as I go on road anyway). Tomorrow should be fun - 4x Clio 172s in my class

Shot water pump bearings perhaps. I had this and sounded like a dry camshaft, was awful. It was a brand new pump from Peugeot too, had 2 that did it. Shocking. Screwdriver on the pulley..
