- To check for wear, insert NEW valve in clean valve guide until stem end is flush with spring end of guide. Use dial indicator to check that lateral (rocking) movement is not more than .051" (1.3 mm) when moved back and forth against indicator.
- Prior to replacing worn guides, check that head is not cracked and that valve seats can be refaced. Press out old guides and coat new guides with oil. Press new guides in up to shoulder but DO NOT use more than one ton of pressure once shoulder is seated. Hand ream the guides to a uniform diameter of .315-.316" (8.013-8.035 mm).
