On my 90 4Runner the clutch is not entirely disengaging when I press the clutch pedal down.

I've adjusted the pedal height so that's not it.

I'm thinking its got air in the hydraulic line and needs to be bled. The hydraulic reservoir has been run dry before, and I think I just did a bad job bleeding the line.

The guy who is looking at buying it from me is trying to tell me that he thinks it needs a new clutch all together. I don't entirely believe him, but I'd like to know what you guys think.

 

Bleed it and find out, takes 10 seconds.

Though, when this happened to me I was missing about 8 teeth from my pressure plate.

 

could be a bad slave cylinder

 

Could also be an air bubble. Bleed it.
