turbo fault lots of hissing

[cwspellowe]

Turbos fecked then fella. Stalling noises when changing gear were a symptom of my knackered turbo. The revs drop, engine doesn't demand the air the turbo is still forcing in, easiest way out is for the air to stall the turbo which makes the dumping noise as it comes back out the inlet.

When it starts doing this, usually after being run at excessive psi, the bearings don't last long. It'll probably start sounding like a police siren soon when the compressor blades grind themselves to death on the housing.
