N00b here.I just bought a 1990 Toyota 4Runner (i know, 3.Slow, heads can crack etc.) but my question is about the clutch. Sometimes, when I fully depress the clutch pedal, then release my foot, the clutch pedal stays to the floor. Also at these times I cannot shift the transmission. Another related problems seems to be that it grinds going into reverse with the engine running and the cluthc depressed. Any ideas or insight on this?
