These turbo guides look at common turbo faults one at a time. The pattern is nearly always the same: a turbo is designed to last as long as the engine, so when one fails early, something else has usually let it down, most often its oil, debris, heat or overspeed. That cause will ruin a rebuilt or new turbo too unless it is found and fixed.
Each guide draws on published guidance from turbo and engine component manufacturers, including Garrett, BorgWarner, MAHLE and Holset, and lists its sources. Start with turbo failure for the overall picture, or pick the symptom you are dealing with below.
