Your head gasket is a vital part of the engine. If it’s not working as the manufacturer intended then this can lead to bigger problems. You’ll find this critical seal between the engine block and the cylinder heads. It should be typically made of steel or copper, although some manufacturers use graphite and there are even asbestos gaskets in older cars.

The gasket helps ensure that the engine remains fully pressurised during the combustion process. Remember that the dynamic release of energy when fuel is ignited drives the pistons – so any drop in pressure means a drop in power. Oil and coolant are also supplied to the engine through the gasket, which means that problems with the part could lead to cross contamination between the two fluids – a problematic scenario for any engine.

Signs that You Have a Failing Mass Air Flow Sensor

The mass air flow sensor (MAF) is a critical component in your car’s fuel injection system. It sits nicely between the air filter and the intake manifold, carefully measuring the amount of air that’s being drawn into the engine to drive the combustion. The sensor sends the information to the Engine Control Unit (ECU), which in turn delivers the correct amount of fuel to the engine. As the sensor picks up different information about air density, temperature and other variables, it ensures that the engine functions at the most efficient level.

The 7 Signs That Could Mean Your Throttle Body Needs Cleaning

throttle body needs cleaning

In modern fuel injected cars, the throttle body is an essential part of the air intake system, controlling the flow of air into the engine, which is used to effectively combust fuel in the pistons. Getting the right amount of air is vital. Too much air or too little air can make your engine run lean.

When the throttle body is working correctly, it is synchronized with the fuel intake and the accelerator pedal. Put the pedal down and the flow of fuel is increased into the engine and the throttle body pulls in extra air to aid combustion, allowing your vehicle to perform at the best level and run smoothly.
