Characteristics of a healthy car, of course marked by smooth-sounding engine noise. But if you start hearing strange noises that originates on the machine, you should check out. Because the voices may be annoying in driving comfort. If the engine begins to sound, that is a sure sign of damage in that section.
Here are some sources of damage:
1. Voice squeaked a brief in the cylinder head. The reason: the piston scraping the cylinder wall, a broken piston body, piston rod installation error, or less oil.
2. Antarlogam pounding pounding sound (when the machine gets a load or accelerated). If his voice regularly, sliding bearings of the crankshaft is worn. Similarly, if her voice does not irregular and sharp, bearing seat (thrust bearing) is worn.
3. Metallic knocking sound heard when the machine twice with no load. The reason: the piston pin is worn or loose.
4. Clatter at no load or accelerated rounds. The reason: low-octane gasoline, carbon deposits, time is too fast ignition. To repair: replace gasoline with higher octane, clean carbon deposits, and the ignition time set correctly.
5. Vibrating sound during acceleration. The reason: piston ring or cylinder walls are worn or broken piston ring of low voltage.
6. Pounding or throbbing sound that slowly as the piston rises. Cause: worn bearings in the piston, piston rod mounting errors, less oil.
7. The click-click basis. The reason: the movement of the valve. To repair: do gap setting free the valve to the garage.
