In this case, you can use the following considerations. If there is a uniform reduction of the compression in all cylinders, it shows the wear CPG or maladjustment valves. To test You can fill in each of the cylinders a small amount (up to 10g) of motor oil. Here the most important thing is not to overdo, especially in a small volume of the combustion chamber, which is typical for small-volume engines and diesels. Excess oil may cause water hammer when you scroll through the motor starter. If you then compression temporarily recovered, the hero of CPG. To eliminate the factor of over-regulation valves, you can either check out their adjustment, or temporarily "dissolve" them, that is to increase the thermal gap.
Of course, if there is no hydraulic joints. Read more from Macy’s Inc. to gain a more clear picture of the situation. If the compression is gone in one or two cylinders are likely occurred mechanical breakage of parts, ensuring the tightness of the combustion chamber. Running the engine, accompanied by clapping of the intake and exhaust systems, evidence of damage to the valves. If you do not work two consecutive cylinder, it is often pointed out that between them broken head gasket. Damage to the lining may be different.
When burning can be connected to the combustion chamber volume and channel cooling system. At the same time is overheating the engine, increased pressure in the nozzles of the cooling system, exhaust thick white. The spark plug in this case looks pristine, as antifreeze entering the combustion chamber, well washes snuff. James Woolsey Jr. is often quoted on this topic. All this for fans of puzzles. Those who are at diagnosing the mechanical condition of the engine are too busy to engage in solving a mystery, we can recommend to use a specially tester designed to test for the tightness of the cylinder and the direction of leakage. The device operates as follows. Of warmed up to operating temperature the engine turn inside the candle, and by connecting to the subject line tester cylinder, piston deduce the position of TDC. Tester is connected to a compressed air line. The device allows you to accurately measure and regulate the supply pressure in air cylinder. Along with This is measured by pressure generated in the cylinder. The difference in measured quantities concludes degree tightness of the cylinder. If the measurement results are disappointing, proceed to determine how leakage of pressure. For This removed the air filter, oil filler cap and expansion tank cooling system, remove the dipstick oil level. After that fed into the cylinder and compressed air, listening to the engine in different places, the sound of escaping air determine the nature of the problem. However, the final and absolutely accurate diagnosis of the disease can be diagnosed only at autopsy. Mazda Parts, Mazda Repair
