I have replaced the flywheel, clutch plate, pressure plate, throughout bearing, master cylinder, slave cylinder, the system has the damper cylinder. I have bled each several times but still feels like it has air in it. I did not bench bleed the master, could this be my problem?

Welcome to 2CarPros.

Here are the directions specific to bleeding the clutch hydraulic system. Go through it and see if you missed any of the steps.

CLUTCH BLEEDING PROCEDURE

NOTE: If air enters the hydraulic clutch system, it will cause clutch dragging. This procedure must be performed when reservoir has been emptied, or if system has been disassembled.

1. Set parking brake.
2. Check level of clutch fluid in reservoir and replenish as necessary.
3. Remove the rubber cap from the bleeder screw and wipe clean the bleeder screw. Connect a vinyl tube to bleeder screw and insert opposite end into a transparent container.
4. Pump clutch the clutch pedal several times, then hold pedal depressed.
5. Loosen the bleeder to release clutch fluid with air bubbles into the container, then tighten bleeder screw. Do not release clutch pedal until bleeder screw has been tightened.
6. Release the clutch pedal carefully. Repeat the above operation until air bubbles are no longer seen coming out of vinyl tube. During bleeding operation, ensure reservoir is kept full at all times. Reinstall rubber cap onto bleeder screw.
7. If the reservoir cap diaphragm is stretched, re-shape it into its retracted position, then install cap on reservoir.

Let me know if this helps or if you have other questions.
