2. N/a mani to exhaust section gasket / ring thing lol. 12 and 13 look like dizzy cap ring seals. one possibly for the water pump pipe at the back that has a ring on it about that size so the other larger rubber may be for the dizzy as i dont know what size the second one is. 15. oil pump ring. if 14 is made of rubber i cant tell it may be the small rubber ring for the bottom of your oil pickup. could also be 10 tho.
