Turbo discovery
I have a turbo that I bought which is the latest remanufactured from ford.
It has part # 5C3Z 6K682. I opened up the turbine exhaust side so I could look at the design of the unison ring and the veins. I thought maybe I could come up with a different material for the unison ring that would resist rusting. I used a magnet on the ring and low and behold it is completely non magnetic. This means to me it is already made of some kind of material that does not rust. The veins had a slight amount of magnetism and of course the housing itself pulled very strong. So has ford changed the material that the unison ring is made from, to help stop the sticking problem? Has anyone ever had an older one apart and notice that the older turbos had a unison ring made of steel? Just curious if there were other changes made other than the machining they did on the housing to allow for less contact of the unison ring.
