So a few months ago I was boosting hard in 3rd gear and stopped building boost. I got it home and the car was a few quarts low on oil when I checked the dipstick so I figure that had something to do with it.
I got it home and pulled the intake off then tried to turn the compressor wheel. It was siezed. Today I took the Turbo apart by removing the center clamp. I grabbed the Turbine and turned it counter clockwise. I can hear a clicking noise from the turbine when I turn it counter clockwise by hand (but no real friction). The compressor wheel turns smoothly with no rubbing at all just like that and all of the sudden.
I see a few small dings on the compressor wheel but my rough guess is that this is no big deal.
I see alot of talk on different forums about the center housing being "junk" if the compressor wheel touches the center housing. How do I know that the center housing is officially "junk" or when it can be reused. It does look like the compressor has rubbed the center housing but it doesn't look bad at all in my opinion which probably means nothing.
I pushed the compressor wheel in and out and there is a little bit of play and also side to side there is a little play (possibly enough where it might rub but not sure).
Also, should oil have been pouring out of the turbo? I saw very little come out of the oil line.
Finally looking for any links or information on how to get the compressor wheel out so that I can measure it with dial calipers and see if it is really a Big 16g or not? Previous owner claims its a Big 16g but the housing is for a small 16g.
Any ideas on how to proceed? Not really looking to buy a turbo until I can find out what is what so no pm(s) please.
Thank you
