I second Chris' comments above regarding the block holding down studs. It is a far better option to accept a bit of oil seepage from the block/crankcase joint than to overtighten one of the holding down nuts and risk breaking one. If the joint is seeping no amount of tightening will stop it. The only remedy is an engine strip, a proper clean and a silicone gasket. I snapped the middle one in the valve chest attempting this so I know from my own experience that it was a BIG mistake!

The leak on the o/s of your engine does appear to be coming from the oil jet cover nut. That's a reasonably easy fix, just remove it, clean it up and replace with a fibre washer. Again, don't overtighten, and don't drop any rubbish down the hole. You can poke the oil jet with a straightened out paper clip before replacing the cover nut.
