Blown turbo? - not a pun...



Pulled the turbo today, the impellor isn't touching the housing but isn't
far off it - the axle has play in all dimensions and rattles when I shake
the unit. There was something like 2-3 tablespoons of oil pooled in the
intercooler inlet hose but none at all in the turbo - by this I actually
mean in the oilways, I removed the oil feed and return lines and didn't get
a single drop of the stuff out of the turbo - its now been sitting on my
bench for 6 hours and theres still no sign of any.

One of the intercooler mountings was split in two and the other was within a
gnat's of the same thing. The block breather hose is in pretty good
condition, I'm starting to think that the breather hose that fixes to the
air dome may not be as air-tight as it should be, it has two or three places
that are rather worn. Tried fiddling around with my long 3mm allen key in
the mixture ajustment hole again - still no luck, so tried another 3mm,
didn't work so tried a 2.5mm key - fits fine and turns the mixture screw.
