recently my corrado g60 went thump underneath my engine as i pulled up the hill and since then it wont pull away or move or go anywhere :( , the clutch is fine, all the gears go in but when i try to pull away it goes no where and makes a massive grinding noise, has the cv joint bolt broke, help needed, also my 2nd gear crunches ita an 02a gearbox does putting in mt90 redline do the trick, cheers, mark.
