Symptoms of SZ malfunction

To understand the issue of faulty spark plugs, let’s clarify what the symptoms of this breakdown are:

1. The engine does not start, or it starts, but you have to turn the starter for a long time.
2. There is a loss of power when the engine is running, and when you press the gas pedal, dips occur.
3. The engine runs rough and there is increased vibration (usually at idle speed).

What affects the wear of SZ

How to determine a malfunction by appearance:

1. Mechanical damage, deformation of the electrode, washer, ceramic body indicates the following problems:

• the spark plug is not suitable for the engine type;
• cooling system is faulty;
• Incorrect ignition timing.

1. The appearance of black carbon deposits is caused by a too rich air-fuel mixture. It leads to the formation of soot, which weakens the spark.
2. A glossy glassy appearance means that the mixture is lean, which leads to overheating of the SZ.
3. Oil deposits are a malfunction of the piston system or valve stem seals.
4. There are chips on the insulator, indicating sudden cooling or overheating of the SZ.
5. Melted contact – overheating.
6. Red soot is a bad fuel (there are a lot of metal-containing impurities in gasoline).

Important!!! When the engine is running properly, carbon deposits should not be light grayish-brown in color.

Diagnosis of the condition of spark plugs by appearance

The normal color of a candle is brown or yellowish. Soot deposits on the spark plugs may indicate late ignition. It is recommended to check the air filter and temperature sensor.

If there are oil deposits on the spark plug, then repair of the cylinder head is required. The appearance of plaque on the skirt usually leads to a drop in engine power and increased gas mileage.

If the car owner discovers rust on newly installed spark plugs, it is recommended to change the refueling location. Corrosion usually occurs from poor quality fuel.
