Honda 12513-P30-000 is a genuine rubber cylinder head seal sold individually. This service seal is designed to restore the sealed interface specified by Honda when the original component is removed, damaged, hardened, or no longer seals correctly.

A properly seated cylinder head seal helps close its intended opening or passage and helps limit leakage at that location. Replacing a deteriorated seal during appropriate engine service can support a clean, reliable reassembly. Confirm the part number against the engine assembly and service information before ordering or installation.

• A restoration or engine build calls for renewal of accessible service seals during reassembly.

Installation Notes

1. Confirm the part number and sealing location before disassembly.
2. Refer to the application-specific vehicle service manual for removal procedures, cleaning requirements, sealant instructions, and torque specifications.
3. Clean and inspect the mating bore or surface without scratching, gouging, or leaving debris that could compromise sealing.
4. Inspect surrounding components for damage or wear before fitting the new seal.
5. Install the seal squarely and to the specified position using an appropriate method; do not distort or cut the rubber.
6. After reassembly, inspect the area for correct seating and check for leakage during initial operation.
