I have just recently started driving my car again after I had built it, and I am having serious clutch issues. It is a stage 3 XTD clutch with lightened flywheel. When I first drove it, I couldn't put it in gear after first startup. Adjusted clutch pedal and it would finally go in. After 1600 miles, I am having issues again. Sometimes I can't even get it to engage from a stop, into any gear. And while driving, if I Rev up to like 5k or so in any gear and press on the clutch pedal, it does not engage. I replaced the clutch master cylinder and the slave cylinder isn't leaking. Any suggestions? Yes the clutch is bled.
