well the good people at toyota has finally solved the mystery. 2 start off with, yes the dizzy seal was leaking and it was replaced, however he said theres an inner seal that also needs 2 be replaced soon, and i have 2 replace the whole dizzy. but the main leak was coming from a cracked seal on the drive shafts, which connects 2 gearbox(?) which in terms leaks gearbox oil... which means more $$$
