• The Importance of Center Bolt Valve Cover Gaskets
  • A good spark plug is essential for maintaining the health and performance of your engine. It is responsible for creating the spark that ignites the fuel-air mixture in the cylinders, which in turn powers the pistons and drives the engine. A poorly functioning spark plug can lead to reduced power, increased emissions, and poor fuel economy.
  • When it comes to maintenance, it's advisable to follow the manufacturer's recommendations for spark plug wire replacement intervals. It's also important to handle them carefully during maintenance, avoiding excessive bending or twisting that could damage the insulation.
  • The A7TJC spark plug is specifically designed to cater to the stringent demands of high-performance engines. Its construction, with a 7mm thread length and a heat range classified as 'T', denotes its suitability for engines that require a slightly hotter spark for optimal combustion. The 'J' in the model name refers to the gap configuration, indicating a conventional gap setting that ensures consistent ignition.
  • It is important to use the correct type of gasket for your specific engine and to follow the manufacturer's instructions for installation. Failure to do so can result in improper sealing of the valve cover, leading to oil leaks and potential damage to the engine.

  • Proper installation of the 25x47x7 oil seal is essential to ensure its effectiveness. It is important to carefully clean and prepare the surfaces where the seal will be placed, as any dirt or debris can compromise the seal's ability to function properly. Additionally, the seal should be installed with the correct orientation and pressure to create a tight and secure seal.


  • The steering rack, also known as the rack-and-pinion gear, converts the circular motion of the steering wheel into linear motion that steers the wheels. The oil seal, usually made from durable materials like rubber or polyurethane, is strategically placed to guard the interface between the steering rack and the gear box. Its primary function is to maintain the integrity of the hydraulic system by sealing in the high-pressure steering fluid, preventing it from escaping and contaminating other parts of the car.
  • As oil is an essential component in many industries, the importance of oil seals cannot be overstated. Oil seals are used to prevent the leakage of oil from machinery and equipment, ensuring smooth operations and preventing damage caused by oil leaks.

  • A patent for an oil seal was filed by Nelson Thomas Edward on August 12, 1937, and published a year later. There were two purposes described. The device was to provide an oil seal between a fixed housing and a rotating part. The seal is described as

  • They are typically made from elastomers such as rubber or silicone and consist of an outer metal case with a sealing lip on the inner side.

  • The rubber used in oil seals is typically a synthetic blend, often a combination of nitrile butadiene rubber (NBR), fluoroelastomer (FKM), or silicone rubber, each with its own set of advantages. NBR, for instance, boasts excellent resistance to oils and fuels, making it ideal for automotive applications. FKM, on the other hand, is more resistant to high temperatures and chemicals, finding its use in aerospace and chemical processing industries. Silicone rubber, with its wide temperature range tolerance, is commonly employed in food and medical industries.

  • The National Skeleton TC Oil Seal features a rubber or silicone lip that fits securely into a housing to create a tight barrier against leaks. It is made from high-quality materials that are resistant to wear and tear, ensuring long-lasting performance. The seal is also designed to withstand high temperatures and pressure, making it suitable for use in a wide range of industrial applications.
  • Improper use of sealants.
  • O-rings are made to be elastic as they are usually stretched to fit into a groove before being compressed. You need to be careful of how you stretch the o-ring while installing it. In fact, you should stretch it more than 50%, and the stretching should be on all the sides, rather than one side.
