Gaskets are critical sealing components that prevent leaks at the interface between engine parts. They must be replaced whenever components are disassembled for service or repair - never reuse old gaskets as they compress during installation and lose their sealing ability. Always use quality replacement gaskets that meet or exceed OEM specifications to ensure proper fit, material compatibility, and leak-free operation.
