There are only 3 places that commonly leak. The clutch master cylinder, the clutch slave cylinder, and the flex hose that attaches to the clutch slave cylinder. The master cylinder leaks from the back, which is in the passenger compartment. You have to lie down with your head under the driver's side dash and look up to where the push rod goes into the back of the master cylinder. A flash light helps. To check the slave cylinder, you have to pull the boot back and see if fluid is collecting inside the boot. If the flex line is dry, it is not leaking.
