🔍 Key Concepts

• How leaking oil seals could let lubricating oil enter the air intake or exhaust side of a turbocharger • What happens when an engine gets an uncontrolled fuel source (like lube oil mist or droplets) in addition to normal fuel • Fire risk in areas with hot surfaces (turbocharger casing, exhaust manifold) and oil leaks

💭 Think About

• If lubricating oil leaks past the turbocharger oil seals, where can that oil go, and what effect might it have on engine combustion? • Could leaked lube oil act like an extra fuel source for the engine, and if so, how might that affect engine speed and the ability to stop the engine? • What happens when oil contacts the very hot metal of a turbocharger or exhaust system?

✅ Before You Answer

• Think about whether each option (A, B, C) is plausible based on how a turbocharger and diesel engine work • Ask yourself: can a single type of fault (oil seal leakage) reasonably cause more than one of these effects at the same time? • Before choosing, verify which options are clearly linked to oil acting as fuel and which are linked to fire hazard on hot surfaces
