Your right they are one way valves or more commonly called check valves, (search "check valves") They are an essential part of the turbo control system. You can get the OEM replacements from a Mazda dealer or search the forum for "Dale Clark" he sells a good aftermarket replacement.

Are you talking about the sensor directly above the trailing plug on the front rotor housing with one wire come out of it? That is the knock sensor, and it is common for it to leak some black oose, but it doesn't mean that it has failed.

Ahh. The round tank bolted to the bottom of the throttle body? that's the catch can for the evaporative recovery system and as far as i know it's empty. It is attach to the charcol canister but, that's back by the fuel tank.
