Valve Guide: Replacement
- Valve Seal and Valve Spring Seat - Remove
- Valve Guide - Remove
1. As illustrated, use a commercially available air-impact valve guide driver (A) modified to fit the diameter of the valve guides. In most cases, the same procedure can be done using the valve guide driver, 5.35 x 9.7 mm and a conventional hammer. 2. Select the proper replacement valve guides, and chill them in the freezer section of a refrigerator for at least an hour.
3. Use a hot plate or an oven to evenly heat the cylinder head to 300 °F (150 °C). Monitor the temperature with a cooking thermometer. Do not get the cylinder head hotter than 300 °F (150 °C); excessive heat may loosen the valve seats. Factory Service ToolsUse the Manual With the Right Hardware
