Need help with my rx8

Ok so I just recently bought a used rx8 2005 and since I'm not an expert mecanic and not know alot was looking for help from experts on rx8 and all that. When I started my car it just emptied the water Idk how much but water became to come out through the bottom of the car. My brother in law said it could be the manifold but Idk since I don't know alot. Also no water has been in the engine because I checked the oil but it was not chocolaty color but my friend did say it smelled a bit like gas, but he doesn't know much about rotaries either. If I couldreally get some help, also the car was just parked and yesterday when I got ready for work and went outside, it seemed like it also spilled some Trans oil because it looked violet pinkish color instead of the yellow color motor oil has please really need some help. Don't know if I'd need a new engine or fix something else which would be a bit cheaper. Thanks in advance and good day thanks for reading
