Possibly seized?

Well, I had a load on the motor the yesterday and something gave out on me. Oil spilled out everywhere and so on. I coasted into a parking lot and shut it off. I went up today and replaced the filter and tightened the housing nut down and the leaking stopped.

However, the turbo sounds like it's scraping on the inside of the compressor housing. I have a feed line to the turbo that consists of brake line and fittings that works better for me, so I added oil directly to the turbo and it still continued to chatter like it was hitting the housing.

I drove it about a mile or so to where it's parked now, and only tried to boost once. It would only hit 5psi at about 4grand and then above that it would just sputter.. almost like a downgraded version of fuel cut.

I felt the turbo for shaft play and it's minimal and still spins, but it doesn't feel like it's spinning freely. I thought maybe the shaft had seized on the turbo but it still spins when the car is on because you can hear it scrape the housing.

Any ideas? I'm going to run some sea-foam tommorrow and then change the oil and see if I can get anywhere with it. Any help is rewarded with some rep points though. Thanks

Well, it is possible that the turbo went south when you lost oil pressure but unlikely with your description. If the turbo had enough play to hit the housing during running, you would be able to feel the shaft play.

I, myself, would pull the valve cover and remove each cam cap and check for scoring. You can remove/reinstall them 1 at a time to check them out. I have personally seen this happen with a leaking oil filter and the noise turned out to be th #2 ex cam cap was scored from the low oil pressure.

Actually scoring was one of my first thoughts. But I can cleary hear the scraping comeing from the turbo. I'm running MAFT setup so there's no intake on ATM, and when I feel in the turbo you can feel that it's not spinning freely.

I also forgot to mention that I had some extremely low oil pressure afterwards. It still ran and my pressure was just barely above the minimum line, but my oil pressure is generally high.

You said you checked for shaftplay and you can hear it scraping, but did you look at the compressor inlet and actually check visually whether the comp. wheel was making contact with the housing? It will be blatently obvious because the outside of the comp. wheel blades will have marks, and the inside of the comp. housing inlet will have marks from where the wheel hit. Just take a look in there so you can make sure that this is infact what is happening. Take a picture and post it even.
