Had a constant oil leak from the right side case (clutch cover & filter housing). I did not want a JB Weld or RTV temp fix. I removed it, wash it, opened the gap a bit, drilled holes at each end of the crack, cleaned with a wire brush and used Harbor Freight aluminum welding rods. Sat it on some bricks, used a simple MAPP gas torch, gave the general area a good warm up and then concentrated the heat in one area for about two minutes. Then touched the cracked area with the rod, and it flowed like solder. Dressed the welded aread with a Dremel tool sanding drum, leak tested it. 100% leak free. Will paint it this weekend. I would consider this brazing or silver soldering since the base metal does not melt, only the rod. Look at the picture.
