So, the PCV valve system, is one of the oldest and most used emission control devices, in today’s engines. And, although its name might sound very complicated, it is a very simple device. The PCV Valve […]
Knowing how the PCV valve actually works, is the first step in diagnosing a bad or failing one. When your engine is running, thousands of powerful explosions take place, to release the fuel energy. But, […]
First of all, the (PCV) System is the short form or common name, for the Positive Crankcase Ventilation (PCV) System. So, the Positive Crankcase Ventilation (PCV) system, is basically a one way passage. And, is […]
Replacing a (PCV) valve, isn’t difficult. But, sometimes accessing it can be a struggle, depending on your vehicle. So, most people don’t realize how important regular maintenance is, on your (PCV) system. And, then only […]
Did you know the most common problem, in the (PCV) system, is a plugged up (PCV) valve. Another problem, is a lack of air flow, to carry vapors, away from the crankcase. Because, without air […]
The exhaust gas recirculation (EGR) valve, does exactly what the name implies. It circulates, exhaust gas, for a second time. So, exhaust gas recirculation (EGR) valves, do not normally require maintenance. But, they can become […]
The (EGR) valve system, is designed to help minimize, harmful oxides of nitrogen in the air we breath. To help do this, the (EGR) valve allows, a calibrated amount of exhaust gas, to reenter the […]
So, a loose gas cap is among the many causes, for a (CEL) check engine light to come on. In fact, a loose gas cap, is actually the most common cause, of a (CEL) check […]
Replacement of a good Oxygen Sensor, is a common mistake made by (DIY) mechanics all the time. So, before replacing any Oxygen Sensor, you must find the real problem first. First, the Oxygen Sensor is […]
EVERY VEHICLE BUILT SINCE THE EARLY 1980’s, HAS ONE OR MORE (O2) OXYGEN SENSORS INTEGRATED INTO THE EXHAUST SYSTEM. So, (O2) oxygen sensors, confirm, that the proper air/fuel ratio, is actually reaching the engine. Consequently, […]
The function of the (EVAP) evaporative emission system, is to trap and store evaporative fuel emissions. Therefore, the (EVAP) evaporative emission system totally eliminates fuel vapors, as a source of air pollution. However, sealing the […]
So, ford has used emission thermactor plugs, for small block heads for many years. These emission thermactor plugs are useful, when installing a pair of emissions legal heads, on a non-emissions engine. So, ford designed […]
So, a catalytic converter, is a device used to reduce the emissions, from an internal combustion engine. Consequently, the catalytic converter works, by breaking down unburned gases, left over by the combustion process. But, requires […]
The air pump – secondary air injection system (AIS), is actually a part of the exhaust system. Since no internal combustion engine is 100% efficient, there will always be some unburned fuel in the exhaust. […]
Emission control systems, help control fuel fumes, while cleaning engine producing exhaust gases. Consequently, emission control systems, have been efficient in reducing air pollution, caused by automotive engines. So, emission control systems, depend on a […]
