SOOT BUILD-UP – IS YOUR ENGINE STRUGGLING TO BREATHE?
Take a look at this! 👀
This is what can happen inside your engine's intake system over time. Heavy soot and carbon deposits can restrict airflow, affecting how efficiently your engine operates.
🔧 What causes soot build-up?
On diesel engines, one of the main causes is the Exhaust Gas Recirculation (EGR) system. Exhaust gases are fed back into the intake to help reduce harmful emissions.
Over time, soot from these gases can mix with oil vapour from the crankcase ventilation system, creating thick, sticky carbon deposits.
Other contributing factors can include:
❌ Frequent short journeys and stop-start driving.
❌ Excessive oil vapour entering the intake system.
❌ Faulty EGR components or poor combustion.
❌ Underlying engine faults causing excessive soot production.
⚠️ What problems can it cause?
* Reduced engine performance and sluggish acceleration.
* Poor fuel economy.
* Engine management warning lights.
* Restricted airflow and incorrect air readings.
* EGR and intake flap faults.
* Potentially expensive repairs if left unresolved.
🔍 At Autowerks Ltd, we don't just guess and replace parts!
We investigate the cause of the problem, assess the extent of the build-up and advise on the appropriate repair.
Cleaning the intake may be necessary, but identifying WHY excessive deposits have developed is just as important.
💜 Don't wait until your engine is struggling to breathe!
