Honda OEM Camshaft Plug 12513-P72-003

The Honda OEM camshaft plug 12513-P72-003 is a genuine sealing cap used on many Honda engines to close and seal the end of the camshaft. Its role is to prevent engine oil from leaking out of the rear side of the cylinder head – an area where older engines, especially with high mileage, often develop seepage if the plug hardens or shrinks over time. This genuine part is made from high-quality, heat-resistant material designed to ensure long-term, leak-free operation.

The 12513-P72-003 plug is used in a wide range of Honda engines, including the classic B-series and D-series, as well as newer R-series engines and hybrid LDA units. Replacement is often recommended during timing belt service or whenever oil residue appears on the rear section of the engine.

Installation notes

The camshaft plug is installed by gently pressing it into the camshaft bore at the rear of the cylinder head. For best sealing, lightly lubricate the outer edge with engine oil before installation. If you notice oil residue on the rear side of the engine block or gearbox housing, checking this plug should be one of the first diagnostic steps.
