I hope someone can help me?

I have a '98 UK Turbo done about 92K. The clutch has juddered all the time I have had it and the bite point is quite hi. Recently as the turbo comes in the rev counter as shot round from 2.5k to around 4k with a speed faster than a Macca. unfortunatly acceleration is not quite as impressive...

I have come to the conclusion that I knew I would that the clutch now needs replacing.

I am hoping to get away with just replacing the friction plates - is this feasable? Also how difficult a job is it?

Other issues I have are I had the cam belt replaced at Scooby Clinic at 88K (they where very good) along with aircon and drive belt. If I drive the car hard (but of course within speed limits) I start to get a belt whining noise and a slight vibration through the steering wheel. Any ideas? I have recently replaced the oil with Mobil 1 but havent done the gearbox and diff oils.

Finally how do you change the spark plugs!!!!
