Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.

Regular maintenance is vital to prolonging the life of your timing belt set. It’s advisable to check the owner’s manual of your vehicle for specific recommendations on timing belt replacement intervals. Generally, timing belts should be replaced every 60,000 to 100,000 miles, depending on the manufacturer’s guidelines. During replacement, it’s wise to replace the entire timing belt set, including the tensioner and idler pulleys, as these components are frequently subjected to wear and tear.
