There are many causes of turbo failure. Theoretically, a turbo should last indefinitely if it is supplied with plenty of clean oil, debris is kept out of the wheels, it is not abused by overfueling, and is not subjected to hot shutdown. Most failures that are a the result of an incorrectly assembled or defective turbo will occur within the first few hours of operation. After that time period, the failure is usually the result of something other than the turbo itself. If you have a failure right after installing a rebuilt turbo, it is very important to determine the cause of the failure before installing another. If the problem is not corrected, you can look forward to another failure. Your turbocharger specialist can assist you in determining what to look for. A failed turbo will generally tell the story once it has been analyzed. Your original turbo may have lasted 5000 hours but failed in the last 1 hour of operation.
