Description
Overview:
This breather valve is a Genuine Villiers part for classic MK-series small engines, supplied under manufacturer part number EM 207. Built with a robust metal body for long service life, it regulates crankcase ventilation so pressure can escape while limiting oil mist carry-over. Correct ventilation helps engines run consistently and protects seals and gaskets over time. Suitable for a wide range of vintage machinery using Villiers power units, including lawn and garden equipment, light construction tools, pumps and generators. Ideal for maintenance and restoration of engines such as the Villiers MK10 and MK12, it is unused old stock, so it may show minor tarnishing from age but retains full functionality. A practical, direct-fit solution for keeping classic engines working as intended.

A practical choice for routine servicing, preservation and full restorations of classic engines.
