2. Noisy Engine A loud ticking noise from the engine can indicate that the timing belt, or the associated components, is failing.

- Black spark plugs can indicate a variety of issues within the engine. One common cause of black spark plugs is a rich air-fuel mixture, meaning that there is too much fuel being delivered to the cylinders in relation to the amount of air. This can lead to incomplete combustion, resulting in the build-up of carbon deposits on the spark plug.
- The primary function of the power steering oil seal is to create a tight seal between the steering gearbox and the steering column. This seal prevents the power steering fluid from leaking out of the system, which can lead to loss of power steering assist and reduced fuel efficiency. Additionally, a leak can cause the power steering fluid to become contaminated with dirt and debris, which can further damage the system and require costly repairs.
- * Neoprene Known for its ozone resistance, oil resistance, and chemical resistance, neoprene is an excellent choice for high-temperature and harsh chemical environments.
- Labor costs are another important factor in the cost of spark plugs and wires. The manufacturing process involves a variety of tasks, such as casting, machining, and assembly, which require skilled workers. The cost of labor depends on factors such as the wage rate, working hours, and benefits provided by the employer.
• High eccentricity-following lip shape
- In addition to helping ignite the fuel in certain conditions, the spark plug also plays a role in maintaining the proper temperature of the combustion chamber
diesel engine spark plug. By providing an additional source of heat, the spark plug helps to ensure that the engine operates at the optimal temperature for combustion. This is important for maximizing fuel efficiency and reducing emissions.

There are different types of spark plugs available on the market, each designed for specific engine types and operating conditions. The most common types are copper, platinum, and iridium spark plugs. Copper spark plugs are the most affordable and provide good performance for everyday driving. Platinum spark plugs offer better longevity and performance, while iridium spark plugs are the most durable and provide the best spark performance.

The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
