🔌 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
