Starlet P8 transmission oil

Servus, so I’m having 2 problems with my Starlet.. 1) There’s a hole in the gearbox… looks really shitty in my opinion. Would you like to come in with the screwdriver? What do you think about it? Fill up some gear oil and see if it runs out directly? If yes, try sealing with cold metal and then give in gear oil again? Question: How much gear oil comes into the Starlet if it’s completely empty? 2) The thin plate between the engine and gear seems leaking too. I think that’s a common mistake. Therefore, question: Is the engine or transmission oil? Would be nice if someone could help me with it. Pictures are included, here in the forum and also at imageshack.us here -> http://img708.imageshack.us/gal.php?g=img02581.jpg Furthermore: Are the 2 large bus screws when looking at the transmission from above to refill the screws to the transmission oil? If no, where are they? Thanks already in advance Sebastian
