Ok, so I am in the process of my single swap and let me say first that I took to time to really look at the mazda twin sequential system and how it is set up. It is truly amazing. Quite a piece of work... Anyway, to my problem. After removing the turbo manifold from the housings I notice some oil coming out of a small hole next to the front exhaust port. Can anyone tell me what this leads to (if anything) and if I should be concerned that there was some oil coming out of there? I have checked all through the FSM but cannot get any idea of what this is. Thanks for any help.
