Solution 1. Just buy a new engine with same internals. Then use it until it's finished. Then change the parts of of your current engine to the new engine's crank case and you have the ok-engine again.
Solution 2. Try to find a finished used engine from ebay etc.. Take the crankcase from that...
Solution 3. Try to seal the current crank case. (glue, sealant, welding....)
Solution 4. Buy a new crank case from novarossi. (I wouldn't do that, too expensive for a used engine)
