First, Welcome to Pinside, the EM section. We are all here to help you, but you first have to help yourself.
So many wrongs. Where do you live? Do you have the manual and schematic? If not, you can download the schematic at the Internet Pinaball Data Base, IPDB.org. You can download the Space Mission manual, it is helpful but not necessarily the same as a Space Odyssey manual. You can purchase a Space Odyssey manual from The Pinball Resource. It is difficult for us to help you if you do not have the manual and schematic. Plus you need to understand how to at least read the manual. The schematic is a self learning curve.

You never oil anything in a EM pinball machine. Machines were designed to play dry. Oil will only complicate things.
