Engine noise at certain RPM

[Martin_172]

Here's one for the gurus, it's got me stumped!!

Car is a 2001 1.2 16v sport, it's developed a new noise, it sounds like a very bad wheel bearing but it only does it at 4300rpm! Sounds perfect under that and disappears around 4500rpm.

Now before everyone thinks I'm a mad chav ragging about a 1.2 Clio, the issue is because of its gearing, it happens around my early morning motorway cruising speed in 5th 😂

Only work I've recently done is a driver's side drive shaft, however given it happens at a set RPM in any gear I can't see how this would cause it. - also I don't know if it started directly after this due to the fact I never rev it that high in any other gear and don't always reach that speed in 5th - but I do know it never used to do it.

• It's worse on full throttle, and half as bad on half throttle if that makes sense.
• Same RPM, every gear
• Lift off it completely disappears - so only under load
• The noise resonates thru the cabin enough to cause the dash etc to vibrate

I'll upload a video HOWEVER the camera doesn't pick it up well, and anyone I've shown so far has just got fixated on the dashboard rattle that's a consequence of the "engine" noise.

That sounds like my noise, and It's the clutch cable vibrating. Put your foot slightly on the clutch and see if the vibration stops.
