What Our Customers Say
Restore Lost Performance, Efficiency & Reliability
Over time, carbon deposits build up inside the intake system, restricting airflow and reducing engine efficiency. This is particularly common on direct injection petrol engines, but many modern diesel engines can also suffer from severe carbon accumulation.
At EcoMax Tuning, we offer professional walnut blasting and intake carbon cleaning services to remove stubborn carbon deposits and restore engine performance.
Walnut blasting is a specialist cleaning process that uses crushed walnut shell media to safely remove carbon deposits from intake valves, intake ports, manifolds, and other intake components without damaging the engine.
It is widely regarded as one of the safest and most effective methods of removing carbon build-up from modern engines.
Petrol Engine Carbon Build-Up
Direct injection petrol engines do not benefit from fuel washing over the intake valves. Over time, oil vapours from the crankcase ventilation system can stick to the intake valves, creating thick carbon deposits.
This can lead to:
- Reduced power
- Poor throttle response
- Rough idle
- Misfires
- Increased fuel consumption
- Engine hesitation
Walnut blasting removes these deposits and restores airflow to the engine.
Diesel Engine Carbon Build-Up
Many modern diesel engines suffer from significant carbon build-up within the intake system due to the EGR (Exhaust Gas Recirculation) system.
Some engines are particularly prone to this issue, including the Mazda Skyactiv-D 2.2, where carbon deposits can become so severe that intake ports and manifolds become heavily restricted, dramatically reducing airflow and performance.
In severe cases, carbon build-up can contribute to:
- Poor performance
- Reduced fuel economy
- Excessive smoke
- Turbocharger inefficiency
- Fault codes
- Engine management lights
By cleaning the intake system and removing carbon deposits, airflow can be restored to near-original levels.
EGR Valve Cleaning
Carbon build-up doesn't just affect the intake manifold. EGR valves can also become heavily contaminated over time.
A sticking or blocked EGR valve can cause:
- Engine warning lights
- Poor performance
- Rough running
- Excessive smoke
- Reduced fuel economy
- Fault codes
During the cleaning process, we can inspect and clean EGR valves and associated intake components where required, helping to restore proper operation and potentially avoiding costly replacement parts.
