flat belt and v belt

When it comes to purchasing automotive parts, the quality of the product is paramount. Inferior belts can lead to slippage, premature wear, and ultimately, engine failure. Opting for high-quality belts like the 4PK993 ensures a longer lifespan and reliability under varying conditions. These belts are typically made from durable materials that can withstand high heat and environmental factors, making them a smart investment for anyone looking to maintain their vehicle's performance.

When it comes to the intricate workings of an automobile engine, one often overlooks the importance of smaller, yet critical components. Among these components is the engine belt, commonly known as the serpentine belt or timing belt, which plays a vital role in the overall functionality of the engine. Understanding engine belt costs involves not just the price of the belts themselves, but also the factors influencing their life span, maintenance costs, and the overall economics of automotive repair.

  • Take off the gasket from the cover flange or cylinder head , noting how it is attached. Some gaskets have tongues that fit cutouts in the flange; others are stuck to the flange with sealant ; some just fit into the flange groove .

  • Can heat to 200 ℃; Most oils 
  • One of the most common issues that arise with the m20 valve cover gasket is leaks. Over time, the gasket can deteriorate due to heat, pressure, and exposure to oil. When this happens, oil can seep out of the valve cover, leading to oil leaks and potential damage to the engine if not addressed promptly.
  • A synthetic rubber used in gaskets, o rings, lip seals, and other moulded devices, Viton offers sealing properties for a range of oil-based applications.  Viton with high fluorine grades will also produce excellent resistance to swell, especially in oxygenated fuel and high-octane blends.

  • Oil seals are a crucial component in many machines and engines, working to prevent the leakage of oil and other fluids. One common type of oil seal is the 25x47x7 oil seal, which is designed to fit specific dimensions of machinery. This type of oil seal is known for its durability and reliability in sealing oil leaks.


  • Identical application as type ST, but the outside rubber surface has a ribbed design to absorb thermal expansion of the housing.
  • Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.

  • Another important consideration when selecting an oil seal is its size and shape. The dimensions of the seal must be precisely tailored to fit the specific requirements of the machine it is intended to protect. This includes the diameter, width, and radial clearance of the seal, which must be carefully calculated to ensure a tight fit and effective sealing action.
  • The side cover may be held by one or more bolts. Undo them, then prise it off carefully.
  • Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.
