Knocking at idle

[mgoode180566]

My 2000 172 has developed a knocking noise ( sounds like tappets if i didnt know better ! ) when at idle and clutch is pushed to the floor. Doesnt sound like clutch bearing either and i cant hear it from under the bonnet , only from inside and i seems to be coming from the driver side. As i slowly lift the clutch it disappears , only happens when pedal is hard against floor. Any ideas ?

That sounds like the Thrust bearing, Done the same thing on my m8's Golf GTI, Had the bearing replaced now its all good... May help may not but thats what it sounds like

Doesnt sound like clutch bearing

Most likely it is though, from your description.

In my experience a clutch bearing tends to squeal and also this cant be heard from the gearbox side. Leads me to believe its not release bearing.

Will be a s**t if it is bearing
