hey guys, so i noticed a leak comming from my r32 gts-4 and tracked it to the gear box drain hole, cleaned it up and then noticed a little crack just next to it. i am very slowly loosing gearbox oil. whats the best way to go about fixing it? can it be done or do i have to buy a whole new gearbox, its only a tiny crack any advice would be much appreciated.
cheers P4t.
