  • The price of car spark plugs can vary significantly depending on a variety of factors, including the type of plug, the quality of the material used, and the brand. Generally speaking, the cost of a single car spark plug can range from a few dollars to over twenty dollars, with the most expensive options being those made from platinum or iridium.
  • The LS3 engine is a popular choice among car enthusiasts due to its high performance and reliability. However, like any other engine, it is prone to wear and tear over time. One of the most common issues that LS3 owners face is a leaking valve cover gasket. This can lead to oil leaks, reduced engine performance, and even engine damage if not addressed promptly.
  • Glow plugs, the diesel equivalent of spark plugs, are designed specifically to aid in cold starts. In a diesel engine, air is compressed to a high temperature, which then ignites the fuel. However, when the engine is cold, this compression may not be enough to ignite the fuel. That's where glow plugs come into the picture. They generate heat before the engine starts, preheating the air in the combustion chamber, making it easier for the diesel fuel to ignite.
  • The dimensions specified in its name—12x22x5—are not arbitrary; they reflect the seal's diameter, height, and thickness, respectively. These measurements must be exact to guarantee a snug fit within the housing it is designed to protect. The 12mm diameter signifies a compact size, ideal for smaller mechanisms where space is at a premium. The 22mm height suggests that this seal is robust enough to withstand a reasonable amount of pressure without failing. Finally, the 5mm thickness ensures that the seal has enough substance to create a reliable barrier against both the outward flow of oil and the ingress of foreign particles.

  • A shaft’s surface finishing will determine how effective the sealing will be. The spiral lead and the direction of the finish tool marks have an impact on the sealing effectiveness. Therefore, it’s imperative to ensure that the shaft surface finishing is maintained.

  • Oil seals are widely used as sealing devices for machines.

    JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
    However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.

    Therefore, this series of columns will summarize the following in order:
    • The structure, functions, and types of oil seals
    • How to select the right oil seal
    • Handling of seals, and causes and countermeasures for oil seal failure

  • Fundamental things and its importance 

  • The material of the valve cover gasket varies, with, cork, and multi-layer steel being common choices. Each material has its advantages and disadvantages. Rubber gaskets are flexible and durable, while cork gaskets provide a good seal but may degrade over time. Multi-layer steel gaskets, on the other hand, offer superior heat resistance and durability, making them ideal for high-performance engines.
  • Regular maintenance is essential to ensure the longevity and proper functioning of the power steering oil seal. This includes checking the seal for signs of wear or damage during regular inspections and replacing it as needed. It is also important to use the correct type of power steering fluid in your vehicle, as using the wrong fluid can damage the seal and reduce its effectiveness.
