After intake cleaning, it’s advisable to use high-quality fuel, adhere to regular maintenance schedules, and consider installing an oil catch can for applicable vehicles to minimise future carbon buildup. Modern cars suffer with carbon buildup and our congested traffic and reduced speed zones all exacerbate the problem. Carbon removal for many cars can be considered part of a maintenance plan.

Walnut shell blasting is an eco-friendly method used to remove carbon deposits from engine components, such as intake valves. Finely crushed walnut shells are blasted at high pressure to clean the surfaces without causing damage, restoring engine performance and efficiency. You can watch a video and learn more about the intake cleaning process here.

Direct injection engines inject fuel directly into the combustion chamber, which can lead to carbon buildup on intake valves over time, as they aren’t cleaned by fuel. Port injection engines spray fuel into the intake manifold, allowing fuel to clean the intake valves, resulting in less carbon accumulation.

The cost can vary depending on the vehicle make and model, as well as the extent of carbon buildup. For an accurate estimate, please contact us directly with your vehicle details.

An intake clean is a specialised service designed to remove carbon deposits, soot, and other debris from your vehicle’s intake system. This system includes components such as the intake manifold, throttle body, EGR valve, and sometimes the turbocharger. The process often involves using walnut shell blasting, specialised solvents, or pressurised air to clean the surfaces without causing damage.

The goal of an intake clean is to restore unrestricted airflow to the engine, improve combustion efficiency, and optimise overall performance. At Intake Cleaning, we use industry-leading tools and techniques to deliver thorough and safe intake cleaning services, ensuring your engine runs like new.

An EGR valve (Exhaust Gas Recirculation valve) is a critical part of your vehicle’s emission control system. It recirculates a portion of the engine’s exhaust gases back into the intake manifold to reduce nitrogen oxide (NOx) emissions. By lowering the combustion temperature, the EGR valve helps minimize the production of harmful pollutants.

Why does the EGR valve need cleaning?

Over time, carbon deposits, soot, and other combustion byproducts can accumulate on the EGR valve. This buildup can cause the valve to malfunction, leading to performance issues and increased emissions. A dirty or clogged EGR valve can interfere with engine efficiency and the functioning of the vehicle’s emission control system. Cleaning the valve helps restore its proper operation, which is important for the engine’s overall performance and for keeping emissions under control.

Symptoms of a dirty or malfunctioning EGR valve:

1. Rough idling or stalling: If the EGR valve gets stuck open, exhaust gases may flow into the intake manifold when they shouldn’t, causing the engine to idle roughly or stall.
2. Check Engine Light (CEL): A dirty EGR valve can trigger the check engine light, often accompanied by error codes such as P0401 (EGR Flow Insufficient), P0402 (EGR Flow Excessive), or P0404 (EGR Circuit Range/Performance).
3. Poor acceleration or reduced power: A clogged EGR valve can restrict the engine’s air-fuel mixture, which results in a noticeable drop in power and acceleration.
4. Increased emissions: An underperforming EGR valve can cause higher emissions of harmful gases like NOx, which can contribute to pollution and cause your vehicle to fail emissions tests.
5. Engine knocking or pinging: A malfunctioning EGR valve might cause an improper air-fuel mixture, leading to knocking or pinging sounds in the engine, which can cause long-term damage.
6. Lower fuel efficiency: When the EGR valve isn’t functioning properly, it may negatively affect the engine’s fuel consumption, leading to decreased fuel efficiency.

Professional EGR Valve and Intake Cleaning

If you suspect your EGR valve is clogged or malfunctioning, it’s a good idea to take your vehicle to an Intake Cleaning service. Expert technicians at these service centres have the necessary knowledge and tools to thoroughly clean the EGR valve and intake system.

Intake Cleaning services typically use advanced methods like Walnut Shell Blasting, a highly effective process for removing carbon and soot buildup from critical engine components. This method involves using crushed walnut shells to gently and efficiently clean carbon deposits from the intake valves and passages, helping to restore engine performance without causing damage.

By choosing a professional service, you ensure that both the EGR valve and other areas of the intake system are thoroughly cleaned or replaced if necessary. This helps improve engine performance, restore fuel efficiency, and lower emissions—all essential for keeping your vehicle running smoothly and efficiently.

A dirty intake system can lead to several issues that negatively impact your vehicle’s performance and longevity. When carbon deposits and soot accumulate in the intake manifold, throttle body, or EGR valve, they can restrict airflow and disrupt the precise fuel-to-air mixture your engine requires.

The consequences of a dirty intake include:

• Reduced fuel efficiency.
• Loss of engine power and responsiveness.
• Increased exhaust emissions.
• Difficulty starting the engine or rough idling.
• Accelerated wear and tear on engine components.

In severe cases, a clogged intake can cause engine misfires or damage to critical parts like the turbocharger. Regular intake cleaning prevents these issues and keeps your engine running smoothly.

Clogged Fuel Injectors

Over time, fuel injectors can accumulate carbon deposits, varnish, and dirt, especially if the vehicle is frequently driven in stop-start traffic or short distances. These contaminants reduce the injector’s ability to spray fuel efficiently, leading to poor engine performance, reduced fuel economy, and increased emissions.

Solution: Intake Cleaning offers professional Injector Service and Replacement as well as Carbon and Soot Removal to restore optimal fuel injector performance. Regular maintenance, including a periodic Port Carbon Clean, can prevent severe clogging and keep your injectors functioning efficiently.

Fuel Injector Leaks

Fuel injector leaks can occur when the seals or O-rings degrade over time. This can result in fuel leakage, causing poor fuel efficiency, strong fuel odours, and even fire hazards if left unaddressed. Common signs include difficulty starting the engine, rough idling, or fuel pooling near the injector.

Solution: If you suspect a leak, our Injector Service and Replacement can address this issue effectively, ensuring your injectors are sealed and functioning correctly.

Electrical Failures

Fuel injectors rely on an electrical signal to operate. Corrosion, wiring damage, or faulty connections can disrupt this signal, causing injectors to misfire or stop working entirely. This can lead to uneven engine operation, loss of power, and increased emissions.

Solution: At Intake Cleaning, our technicians can diagnose and repair electrical issues with your fuel injectors, ensuring that they fire precisely when needed.

Preventative Maintenance for Fuel Injectors

To avoid these common fuel injector issues, regular maintenance is key. Services like Intake Cleaning, Carbon Removal from the Intake System, and Turbocharger Carbon Removal can help maintain your vehicle’s overall performance. For diesel engines, our EGR Valve Cleaning service can further enhance efficiency.

A clogged intake manifold can cause various symptoms, indicating restricted airflow and carbon buildup. Common signs include:

• Reduced engine performance: You may notice a lack of power, sluggish acceleration, or reduced responsiveness.
• Rough idling: The engine may vibrate or feel unstable when idling.
• Poor fuel efficiency: You may need to refuel more frequently as the engine consumes more fuel to compensate for the restricted airflow.
• Increased exhaust smoke: Excessive smoke from the exhaust, especially black smoke, can be a sign of incomplete combustion.
• Check Engine Light (CEL): The engine management system may detect the problem and illuminate the CEL.

If you experience any of these symptoms, it’s essential to have your inlet manifold inspected and cleaned promptly.
