Valve Guide: Service and Repair
REPLACEMENT
1. As illustrated, use a commercially available air-impact valve guide driver attachment modified to fit the diameter of the valve guides. In most
cases, the same procedure can be done using the special tool and a conventional hammer.
2. Select the proper replacement guides, and chill them in the freezer section of a refrigerator for about an hour.
3. Use a hot plate or oven to evenly heat the cylinder head to 300°F (150°C). Monitor the temperature with a cooking thermometer. Do not get the
head hotter than 300°F (150°C); excessive heat may loosen the valve seats.
CAUTION: To avoid burns, use heavy gloves when handling the heated cylinder head.
4. Working from the camshaft side, use the driver and an air hammer to drive the guide about 2 mm (0.1 inch) towards the combustion chamber. This
will knock off some of the carbon and make removal easier. Hold the air hammer directly in line with the valve guide to prevent damaging the
driver.
CAUTION: Always wear safety goggles or a face shield when driving valve guides.
