knocking from around the clutch ?

[armo]

i need a little help i need to try figure out why im hearing knockin in around the clutch .
on start up the car is fine ticking over its fine but when reved up thers a knock coming from near the clutch/flywheel we used a stetiscope to try figure it out .... its not coming from the big ends the cluch and flywheel were out as was everything els and everything was perfect ... i no the clutch oil seal is gone and will be done next week but anyone got any ideas what would be knocking in that area ?

thanks in advance

Mark caffos mini had a similar issue, a knock around the clutch, Im not 100% sure what it was but he had the engine rebuilt. the noise only happened under revs, and came from the clutch side of the engine.
Hopefully its not this, his was a 1275 spi.

Perhaps its a bearing in the transfer gears or the oil pump?

its a 998 a series ...im not realy worried the engine will be taken out next week to do the seal so will be easy enuf to fix its just figuring it out is the problme

Could be one of the drop gear bearings? or the idler bearing

[armo]

thanks

Is it a single knock when reving or a constant knocking when you increase the revs.

[armo]

its a constant knocking when you increase the revs

[macker]

does it go away if you put your foot on the clutch?

[armo]

no it doesnt go away when i put the clutch down

[woody]

Sounds like idler bearings

[armo]

idler bearings they easy done?

[GTM Coupe]

Yeah easy once you get to them but it requires the engine out and the flywheel off, dependent on which bearing has gone depicts on how much further you need to strip the engine, I would say once the flywheel is off you should be able to do them from memory?

[kona]

You *could* do them with the engine in the car? Just take off the casing, but Engine out is waaaay easier, as some of the bolts can be a PITA with the engine in.

[woody]

Its best to replace both at the same time.
Ideally you need an internal bearing puller.
Personlly I wouldn't even try with engine in car.

The puller for the needle roller bearing in the top suspension arm fits the idler bearing.

Grease and a suitable socket will get the one in the housing out

[armo]

by the looks of things i wont be able to pull the engine out any time soon loads of work to do so my own car is left sitting ... anyone any ideas what it would cost to sort this problme an do a genral tune up money is tight but im sick looking at the car in the garden insured and cant be driven
