  What is Engine Flushing? Engine flushing is the process of cleaning up or warding off the  sludge  build-up in the engine. Let’s understand, what causes this sludge build-up. Engine oil is meant to cycle through and lubricate the engine components to help them function smoothly. Basically, engine oil is meant to remain in motion. When a car takes short trips or remains idle more often than not, the engine oil particles start leaving deposits that keep on building up sludge inside the engine. An element as small as 25 microns (approx. 1/1000 of one inch) can be removed by the best of the oil filters available. Particles even smaller than the aforementioned size are there in the oil that just can’t be filtered out. Over time these tiny particles accumulate together and build up sludge. The sludge, however prepared, increasingly resists the flow of engine oil. This issue, if neglected, can eventually lead to major troubles such as improper working valves, spark plugs, exhaust sensors, s

  What is an EGR valve? The EGR valve is a small component, invented to allow the flow of exhaust gases into the intake manifold in controlled amounts. It is a simple valve that closes and opens as needed. The EGR valve has one job to do. Its role is to either open and direct exhaust gases into the combustion chamber or to close and keep the gases from entering. When your car engine starts, the valve becomes active and remains in a closed position, barring the flow of exhaust gases. Once the engine reaches working temperature and speed is increased, the valve — either through a vacuum or electronic control — increasingly opens, allowing burned exhaust gases to enter and combine with the air-fuel mixture inside the combustion chamber. If you slow down or come to a stop, the valve progressively closes and blocks the flow of exhaust gas. The process continues for as long as the engine is running. When the engine is off, the EGR valve closes and remains so. The EGR valve has been a problem
