Which related passage also becomes blocked?

  • A.The intake tract downstream of the valve, where the recirculated soot meets oil mist and builds up over time
  • B.The inlet manifold and its ports
  • C.The exhaust manifold, whose passages are kept clear by the flow of hot gas leaving the engine continuously
  • D.Nothing

Answer: B

The intake tract downstream of the valve gathers the same tarry deposit. The last option explains exactly where and why, which makes it a correct and more instructive version. It can restrict the airflow severely. The order in which the effects act is what decides the outcome, so it is worth establishing first. Naming what changes and what stays the same is the reliable route through questions of this shape. Most errors here come from carrying a result across from a neighbouring case where it does not hold.
