## 🔌 Function

Uses exhaust energy to drive a compressor that forces charge air into the cylinders, raising power and efficiency.

## ⚠️ Common Signs of Failure

-   Whine, siren or grinding from the turbocharger that rises with load
-   Blue smoke and oil consumption, with oil in the charge pipework
-   Loss of boost and power under load
-   Shaft play felt at the compressor wheel, or wheel tips rubbed on the housing
-   Oil leaking past the turbocharger seals into the inlet or exhaust

## 🛠️ Service Notes

-   Change the oil and filter and confirm the oil feed and drain lines are clear before running a new turbocharger - a restricted drain will kill it quickly
-   Clear anything the old turbocharger shed into the charge air pipework and cooler, or it goes straight through the engine
-   Prime the bearing housing with clean oil and crank without starting before the first run
