If it is an internal throwout bearing check the holes where the bleeder is sticking out of to see if the rubber grommets in the Hole for the bleeders to stick out of is gone.if not line with hit the case being there's no rubber grommet there.happened on my 2.5 4 speed after I did the clutch,did the same thing.just give it a look its probably what it is.good luck. P.s my clutches throwout bearing went 4 month later after letting it tick.guessing my line from the throwout bearing got a hole from rubbing
