Continued to remove the dump pipe, and you can imagine my surprise when the turbine wheel fell out of the cat What has happened is that the turbo has been spinning at maximum rpm, the bearings have seized up, possibly because something has restricted oil flow through the small screen in the oil line, and because of the inertia in the heavy turbine wheel, it has twisted itself off the turbo shaft, depositing itself in the exhaust.Turbine housing is not too badly damaged, but I'm not sure of the centre housing, as there is some deformation of the hole where the shaft comes through, and of course the turbine wheel is several mm smaller than what it was originally. Compressor side seems reasonably OK.Fortunately there is no damage to the CAT or dump pipe, but it is going to be either a major repair, or replacement of my turbo - BUGGER!!!See photos below.

Im going to have a bit or a search around to try and find a larger screen that can be remote mounted to make servicing easier. Link to comment Share on other sites More sharing options...
