Turbine wheel missing in action?

[95 gsx]

So...what do you think would make a turbine wheel completely disspear? Yesterday I noticed my car wasnt going into positive pressure at all so my friend and I concluded it obviously had something to do with the turbo. We removed the used 14b from the car and noticed the turbine wheel had snapped off the shaft, spun its way through the o2 housing, mangled the o2 sensor and took out chunks of the housing along its path of destruction. The wheel is nowhere to be found and needless to say, the turbo is a paperweight. What do you think would cause this?

I did the same thing check your cat or exhaust. The shaft got siezed up from to much shaft play, lack of oil, overheated, etc.

You'll definitely want to verify that the turbo was in fact getting oil.

Yeah, good call on that one. I just installed a spare 14b I had laying around and so far it's boosting fine. How would I verify that it is getting oil? Could I disconnect the return line and put a pan underneath it to catch the oil to make sure it is getting to/through the center section?

That'd probably work.

My T25 shaft snapped, but the wheel stayed in the housing. Mine failed over a week or so. Don't know why the shaft broke, but it was howling like a fire engine off and on for several days before it died. The thrust bearing was in 5 or so pieces in my oil pan. Don't know which went first.

And I was getting plenty of oil flow; I reused the oil lines from the T25 on my FPB28, and it's been just fine. And I had enough oil in the intercooler (almost 2 quarts) from when it failed (and I only ran it for maybe 45 seconds total after it blew).

Find the turbine wheel or you may have an undesired exhaust restriction. And it'd probably make for a neat paper weight, too.
