🔌 Function

The valve spring washer sits between the valve spring and its mating surface, providing a flat, hardened seat that keeps the spring correctly located and evenly loaded. This maintains consistent valve spring geometry and prevents the spring from wearing directly into the surrounding components.

⚠️ Common Signs of Failure

• Visible wear grooves, scoring or dishing on the washer face
• Cracking or breakage of the washer, allowing the valve spring to shift
• Noisy valve train or irregular tappet noise from the cylinder head
• Loss of valve spring height or inconsistent spring preload between valves
• Metal debris or wear particles found in the cylinder head during service

🛠️ Service Notes

• Renew as a set when the valve gear is stripped, and keep the parts for each valve together so nothing is mixed between cylinders
• Inspect the seating face for cupping, cracking or a wear step before reassembly and renew rather than reuse anything marked
• Make sure the seat in the head and the face of the washer are clean, with no carbon or swarf trapped underneath
• Fit the correct way up and the correct way round as shown in the workshop manual for your engine, and check the spring and any seal or shroud sit square before the spring is compressed
• Once assembled, check by hand that each valve moves freely and seats fully before the engine is turned over
