How to service and repair an Exhaust Valve and Intake Valve on Ford Expedition?

The first step in valve servicing requires measuring the diameter of each stem at specific points to ensure specifications; new components need installation when dimensions exceed specifications. Examine the valve zones starting from the stem endpoint where you should search for grooves or scoring and reaching the valve face and edge to detect pits, grooves, or scores, then check the valve head for signs of burning, erosion, warpage, and cracking and complete the assessment with a review of the valve margin for wear. Measurement of valve clearance should follow valve grinding procedures before verifying the condition of valve head and seat by validating both angle measurements and margin-width specifications. You must measure the valve seat width before doing specification-based grinding if needed then check the measurements for both intake and exhaust valve seats. After grinding it is vital to measure the installed spring length before performing required shimming to reach the correct final length. The inspection concludes with the usage of the Valve Seat Runout Gauge for determining valve seat runout measurements.
