High mileage-how can one tell if the clutch is starting to slip?

[DominicJeans]

My 172 phase 2 is on 156,000 miles on original clutch-most of those miles were motorway miles so I guess it's why it's lasted this long. However, the clutch 'bite' point is very near the top of its travel. Anyway... my question is- is there a reliable way of testing it or telling if it's slipping? Thanks!

Load it up in a high gear at low speed, put your foot to the floor and see if the revs rise without an increase in speed. If they do, that's clutch slip.

If its going to slip it will be at about 5000-5500rpm generally as thats where they make peak torque. If the revs rise and the speedo doesnt follow then its slipping.

So big hill and 3rd/4th gear and put your footdown. (fifth is even better but thats over 100mph of course)

Great-thanks folks, really appreciate the help.

Also for reference, I have found most 1*2's do naturally have a high biting point

^^^ same all mine have had a high biting point. first time i drove my clio away form a selller i stalled lol

I normally test this on a car i want to buy. put in fifth at low speeds and accelerate, if the revs raise without the car moving the clutch is slipping.
