Yeah i recently bled my clutch and i think i may have taken it to far and sucked in some air, so i think i may have air in the line. Ill check the cylinder like you said. when i pump it, it works fine, but i still get that ticking noise when i press the clutch in, so i think it has crankwalk but other than that it i cant really say the crankwalk is messing anything up.
