FAQ

Q1: How do I confirm this Valve Spring Seat (8-94390783-2) fits my engine?
A: The primary fitment is for the Isuzu 6HK1 engine. We recommend physically comparing the part with your old component or verifying your engine model number (stamped on the engine block). If your engine is a 6HK1, this is the correct spring seat. For other engines, please contact us with your engine model and part number for verification.

Q2: What is the installation procedure for this spring washer?
A: Installation requires removing the valve cover and rocker arm assembly. The old spring seat is lifted out, and the new one (8-94390783-2) is placed in the cylinder head pocket before reinstalling the valve spring and retainer. We strongly recommend using a valve spring compressor tool and following the engine’s service manual for proper torque specifications. Video technical support is available if needed.

Q3: Can I replace just one spring seat, or should I replace all of them?
A: While a single damaged seat can be replaced individually, we recommend inspecting all spring seats on the cylinder head. For consistent valve spring tension and even wear, replacing all spring seats during a valve job or major overhaul is a best practice. This ensures balanced performance and extends the life of your valve train components.
