Finding the engine oil leaking from your car can be alarming, and ignoring it can lead to costly damage. Identification and early action of oil leaks will protect your wallet and your car. But what causes oil leaks, and how can you fix them? In this guide, we’ll explain everything...

Your vehicle’s engine relies on a precise mix of air and fuel to function efficiently. But how does that air get into the engine, and why does it matter? The answer lies in the air intake system, which is a crucial component designed to deliver clean, oxygen-rich air to support...

Your vehicle’s air intake system plays a crucial role in engine performance and efficiency, drawing in and filtering air that enters your engine. But what happens when this system becomes clogged or contaminated? Air intake issues, whether caused by a dirty air filter or contamination in the intake system, can lead to...

Fuel injectors play a vital role in delivering the right mix of air and fuel to your engine for optimal performance and when they fail, this can cause serious problems for your vehicle. Fuel injector issues sneak up on even the most careful drivers and can lead to frustrating performance issues,...

When it comes to reducing emissions in modern engines, one technology stands out: Exhaust Gas Recirculation (EGR). If you’ve ever wondered how your vehicle stays within emission regulations or how it’s able to cut down on harmful gases like Nitrogen Oxide (NOx), the EGR is the answer. In this article,...

Fuel injectors are a crucial component of your vehicle’s engine, ensuring a precise mix of air and fuel for optimal performance. But how exactly do they work, and why are they so critical to your vehicle’s efficiency? In this article, we will explore what fuel injectors do, the different types...

Interested in keeping your diesel vehicle maintenance costs low or running your engine more efficiently? If you own a diesel car, it’s likely that you have a diesel particulate filter (DPF). Understanding DPFs is crucial for any diesel vehicle owner.  In this article, we’ll delve into what a DPF is,...

Seeing smoke coming from your diesel exhaust can be alarming, but understanding what this means, the difference between smoke colours, and how to resolve it can save you from costly repairs and potential engine failure. Whether it’s white, black, or blue/grey, each smoke colour tells a different story about  what’s...

Keeping fuel injectors clean is key for engine performance, and reduced fuel consumption and emissions. Fuel injectors play a vital role by precisely delivering diesel or petrol into your vehicle through tiny openings. When these openings become clogged, it significantly impacts the health of your vehicle. In this guide, we’ll...

Having a clear DPF filter is important for vehicle performance and emission control. A diesel particulate filter (DPF), also known as a soot filter, is designed to trap soot emissions from a diesel engine, thereby minimising carbon emissions from diesel vehicles. The DPF Filter is a compulsory component of a...

Keeping vehicle emissions to a minimum has been a focus of the mechanical engineering industry for quite some time. The introduction of DPF filters (for diesel engines) and EGR valves was a key landmark in this process. Exhaust Gas Recirculation (EGR) valves were designed to reduce harmful emissions and will be...

As road vehicle drivers, we can probably all agree that cars are not the type to give the silent treatment. But, where do we draw the line between normal and abnormal engine sounds? Whining noises tend to fall into the category of ‘abnormal sounds’, although the cause is not always...
