Description
Overview:
The Exhaust Valve 005 Oversize is a genuine Villiers service part for the Villiers MK10 engine. Built from durable metal with a heat‐resistant finish, it restores proper exhaust sealing and gas flow when the original valve is worn. The "005 Oversize" designation commonly indicates a stem that is +0.005 in (approx. 0.13 mm), helping achieve the correct running clearance in reconditioned or worn guides. Supplied as unused vintage old stock, the valve may show light tarnishing that does not affect performance. Designed for reliable operation under the heat and load of small petrol engines, it is suitable for routine maintenance or full rebuilds of MK10 units found in various compact machinery. Genuine Villiers quality supports long service life and consistent performance.
