Turbocharger failures can be attributed too long between oil changes or the lack of oil in the engine. The turbocharger runs at very high speed so the lack of oil will quickly cause overheating and destroy the bearing. Long distances between oil changes cause "Coking" in the turbo lubrication areas which will lead to bearing failure. It is highly recommended to replace the oil supply line when replacing turbochargers. The reason for this is because poor lubrication to the turbo is sometimes caused by a gummed up oil supply line to the turbocharger.

Other problems that can cause Turbo failure is inlet restrictions from dirty air filters, collapsed hoses or undersized air pipes. The less air intake by the engine causes the exhaust to heat up leading to cracking and scaling of the turbine housing. This can also be caused by over fueling the engine. Hot engine shut downs can lead to oil leakage by causing oil to coke up in the oil drain and forcing oil out around the turbine and seals.
Foreign objects are another commen cause for damage to the compressor or turbine wheels.

Things that also could happen is droping objects into the air intake system such as nuts, bolts, and tools.

Turbocharger failures can often be identified by noting that Small puffs of grey/white smoke begin to stream from the tailpipe when coming to a stop. This is usually an indication that the clearance between the impeller shaft and bearings have become excessive allowing oil to leak past the seals. Another indication of excessive bearing clearance is noting that large amounts of oil show up in the intake manifold.

NOTE: In most cases you can pull the hose that goes to the compressor side (silver aluminum side) and see if the veins on the turbo shaft can be moved manually. If not, the turbo is seized and must be replaced. Keep in mind that some failing turbochargers will only lockup once the engine is running because the veins will jam against the side of the compressor housing once the turbo spools up.
