Honda OEM VTEC Solenoid Valve Gasket 15826-RNA-A01

Honda OEM VTEC Solenoid Valve Gasket 15826-RNA-A01

Honda OEM gasket 15826-RNA-A01 is an original sealing gasket used on the VTEC solenoid valve assembly. It seals the contact area between the VTEC solenoid and the cylinder head, helping prevent engine oil leaks and ensuring stable operation of the VTEC oil control system.

This is a small service part commonly replaced during VTEC solenoid removal (e.g. for cleaning the filter screen, fixing seepage, or servicing the valve). It is not meant as a full oil-change quantity product — it’s a gasket only.

FAQ – Honda OEM VTEC Solenoid Valve Gasket 15826-RNA-A01

1) Is this a complete VTEC solenoid valve?
No. This product is only the gasket/seal for the VTEC solenoid valve assembly. It does not include the solenoid itself.

2) Can I reuse the old gasket?
It’s not recommended. Once compressed and heat-cycled, the gasket may not seal properly again. Replacing it helps avoid oil leaks after reassembly.

3) Which VTEC solenoid part numbers does it seal?
It seals VTEC solenoid assemblies such as 15810-RNA-A01, 15810-R1A-H01 and 15810-R6A-003 (reference numbers).

4) Do I need any sealant with this gasket?
Normally no. The OEM gasket is designed to seal on its own if the surfaces are clean and flat. Use sealant only if a Honda service manual specifically requires it for your engine version.
