It would not come up. while later I was able to pull it up and had a clutch on top. We changed the master and the slave cylinder bleed the system to no luck.I had no clutch. Found the bushing was not tight, tightened it and was able to bleed it.Came back about 3 hours later to drive it home. The clutch was back on the floor .Like it was full of air again.

Yeah it happen to me before but what it might be is, check anything where it leak out with clutch push same time u probably need someone to look under to see if anything leak out or making nosie when u push clutch

I mean check anything that connect to clutch before u push the clutch and pushing the clutch

Yes, this can be a very frustrating problem. At the point where you are, even "one-man" speed bleeders with check valves don't work well. Even the smallest amount of air in the system will cause the pedal to go to the floor.

Try gravity bleeding, since you already have air in the system. Remove clutch master cylinder reservoir cap, open bleeder screw on slave cylinder, and have a friend pour brake fluid in master cylinder reservoir, while the clutch pedal is depressed. Gravity should allow the fluid to flow through the system. When you have a steady flow and no air bubbles, close the bleeder screw, fill the master cylinder reservoir to the "MAX Line" (don't overfill), replace the cap, pull up the clutch pedal and ensure it works properly. Hydraulic clutch systems are prone to fail, if they are overfilled. The "trick" is the position of the clutch pedal during the procedure, to allow gravity flow through the system. If having the clutch pedal depressed doesn't allow gravity flow, try holding it up.
