135j6 poly v belt

An interference engine is a type of internal combustion engine in which the pistons and the valves share the same space within the cylinder at certain points in the engine cycle. This design allows for greater efficiency and better performance at higher RPMs but also introduces significant risks if the timing belt—the component responsible for synchronizing the rotation of the crankshaft and camshaft—fails. Understanding the implications of timing belt integrity in interference engines is crucial for vehicle maintenance and engine longevity.

When discussing the timing belt, it is essential to acknowledge the differences between timing belts and timing chains. While both serve similar functions, timing chains tend to last longer than timing belts, often exceeding 100,000 miles without requiring replacement. Timing belts are quieter and lighter than chains, making them a popular choice for manufacturers prioritizing engine design efficiency. However, timing chains can withstand more stress and are generally considered more durable.
