I race a car w/ a 13b, and had misterious clutch sleepage, after removing several times the gearbox, notices the input shaft, somehow collided with rear of eccentric shaft, perhaps loosening the rear plug. Found out while I started the engine with trans housing removed, clutch cover removed, after about 20 secs fast iddle, where the pilot bearing sits, A LOT of engine oil came out, thus contaminating the clutch disc.
I think it needs to be "riveted" again the steel ball that blocks the oil gallery, or press fit a flat disc (about 3/4" dia, or whatever measure) at the very bottom of the eccentric shaft, with a cushion of locktite epoxy weld. Then reinstall the pilot bearing and seal.
