Description
Overview:
The Valve Tappet Shim is a thin, precision steel spacer used to set valve clearance on Villiers 4‐stroke petrol engines. This genuine Villiers part (OEM reference EM219) suits MK20 and MK25 models and helps achieve accurate tappet lash so the engine starts well, runs smoothly, and avoids premature wear. Made from durable, hardened steel, it sits between the tappet/follower and valve train components to fine‐tune the gap without altering other parts. Supplied as unused old stock, it may show light tarnishing from storage, which does not affect performance. Ideal for routine servicing and rebuilds on classic Villiers engines, it restores factory‐correct clearances and supports efficient combustion, quieter operation, and longer component life.
