Why intakes get clogged

On modern diesels, the EGR system feeds sooty exhaust gas into the intake, where it mixes with oil vapour drawn from the crankcase. The combination bakes onto the manifold walls and intake ports, gradually narrowing the passages and starving the engine of air.

Signs of a clogged intake

  • • Poor throttle response and sluggish acceleration
  • • Loss of power, especially under load
  • • Increased fuel consumption
  • • Rough running or uneven idle
  • • Engine warning light in some cases

Our intake cleaning process

  1. Inspect the intake and confirm the restriction
  2. Access the manifold and intake ports
  3. Professionally remove carbon and oil build-up
  4. Reassemble, clear fault codes and road test

Intake clogging usually accompanies EGR and DPF issues. For the best result, we often recommend addressing them together — see our EGR cleaning and DPF cleaning services.

Intake cleaning — FAQs

What is intake / manifold cleaning?

Over time, soot from the EGR system mixes with oil vapour from the crankcase and bakes onto the inside of the intake manifold and ports, restricting airflow. Intake cleaning removes this build-up to restore proper breathing and throttle response.

What are the symptoms of a clogged intake manifold?

You may notice sluggish acceleration, poor throttle response, reduced power, higher fuel consumption, rough running and sometimes an engine warning light. It often occurs alongside EGR and DPF problems.

How is intake cleaning done?

We access the intake manifold and ports, then professionally remove the carbon and oil build-up using purpose-built equipment, before reassembling and testing. Heavily affected manifolds may be removed for a more thorough clean.

Do you clean intakes for all diesel makes?

Yes — intake cleaning is available for the same range of makes we service for DPF and EGR cleaning. Call 02 9667 4008 to discuss your vehicle.
