Description
Overview:
The Rocker Breather End Cap is a genuine Villiers component for petrol stationary engines in the MK15 and MK15/2 family. Made from durable metal, it closes and seals the rocker box breather outlet while allowing controlled ventilation, helping to manage internal pressure and oil mist. Correct breather function supports stable running, protects gaskets and seals, and helps reduce oil leaks. This cap is intended for straightforward replacement during routine service or restoration work, returning the breather system to factory specification. Identified by OEM part number EM1551, it is sized and engineered for an accurate fit on the Villiers rocker box, providing reliable performance in everyday use on tools and machinery powered by these engines.
