  • The heart of any internal combustion engine lies in its spark plugs, and the double iridium variant takes this role to a new level. The term double iridium refers to the use of two iridium electrodes, a material known for its extraordinary hardness, high melting point, and exceptional electrical conductivity. This design not only enhances the spark plug's lifespan but also significantly improves its igniting capability.
  • The consequences of a blown head gasket can be severe
  • Oil seals are integral components in the operation of machinery, serving as a barrier between the lubricating oil and the external environment. Their primary function is to prevent the leakage of oil from the system while allowing the rotation of the shaft. The performance of these seals is critical to the overall efficiency and longevity of the machinery.

  • c. Silicone Rubber (SI) – these compounds operate effectively in a broad temperature range of -58⁰ F to 356⁰ F (-50 to 180⁰ C). Silicone rubber is a leading choice for its resistance to both low temperatures and heat. The high lubricant absorbency of the material minimizes friction and wear. These oil seals are usually used as crankshaft seals. Silicone has poor resistance to hydrolysis and should not be used in oxidized or hypoid oils.

  • Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.

  • Overall, the m20 valve cover gasket plays a vital role in the proper functioning of your vehicle's engine. Regular maintenance and replacement of the gasket as needed can help to prevent costly repairs and keep your engine running smoothly for years to come.
  • The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.
