If you're experiencing clutch problems (e.g., slipping, hard engagement, high engagement point), the issue likely lies in:
* Hydraulic System: Low fluid, leaks in the lines or master/slave cylinder, or a failing master or slave cylinder are common culprits.
* Clutch Disc/Pressure Plate: These components wear out over time and need replacement.
* Throwout Bearing: This bearing can wear out and cause noise or difficulty engaging the clutch.
Instead of looking for an adjustment, you should have a mechanic diagnose the specific problem. Trying to "adjust" something that isn't adjustable could lead to further damage. A proper inspection will determine the actual cause of the clutch issue.
