Who is correct regarding the use of seals and gaskets?

Technician B is correct in emphasizing the importance of using seals and gaskets appropriately in a diesel engine. Seals and gaskets play a critical role in maintaining the integrity of a system by preventing fluid leaks and ensuring proper pressure within engine components. Their correct application aids in engine efficiency, longevity, and overall performance.

When installed properly, gaskets create a tight seal between two mating surfaces, which is crucial for preventing air and fluid leaks that can lead to decreased performance or system failure. Seals, on the other hand, are designed to keep lubricants contained and prevent contaminants from entering sensitive areas of the engine. Misalignment, improper material selection, or inadequate torque can compromise their effectiveness and lead to significant mechanical issues.

Understanding the specifications and material properties required for different applications is essential for technicians. This is a fundamental aspect of diesel engine maintenance and repair, highlighting the necessity for technicians to have sound knowledge and practices regarding seals and gaskets to ensure reliability and efficiency in engine operations.
