the spare turbo has been sitting on a shelf for 10 years and the oil inlet port, air inlet, and water inlet ports were left uncovered. it had all kinds of crap stuck inside. it made a gross grinding noise when i spun the impeller.
so, seeing as how it is a spare turbo and i like to learn how shit works, i took it all apart. here are the bits and pieces:
after i cleaned them all up with lacquer thinner and brake cleaner, i re-oiled everything with 5w30 and re-assembled it. unfortunately, during the clean up phase, i erased the marks i made that told me how the nose on the impeller lined up with the housing. so surely it is now out of balance, right?
how can i fix this. do i have to send it off to some fancy shop? can a local machine shop tackle this?
as always, thanks for the help.
