Frequently Asked Questions

What is included with Honda oil-passage cap 15331-300-000?

One oil-passage cap replacing Honda OEM 15331-300-000 and one O-ring replacing 94608-40000 are included.

How many oil-passage caps are needed for a repair?

One cap-and-O-ring assembly services one cap location. The listed engines do not all use the same number or arrangement, so identify each damaged or removed cap in the correct Honda parts diagram before purchasing multiples.

What should be checked before fitting an oil-passage cap?

Clean the bore and sealing surface, verify the old O-ring has been removed and lubricate the new O-ring with compatible clean engine oil. Install the cap by the Honda procedure and check for leakage after the engine runs.
