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.
CAUTION:
-
Always wear safety goggles or a face shield when driving valve guides.
-
Hold the air hammer directly in line with the valve guide to prevent damaging the driver.
5. Turn the head over, and drive the guide out toward the camshaft side of head.
If a valve guide still won't move, drill it out with a 8 mm (5/16 inch) bit, then try again.
CAUTION: Drill guides only in extreme cases; you could damage the cylinder head if the guide breaks.
6. Remove the new guides from the freezer, one at a time, as you need them.
7. Apply a thin coat of clean engine oil to the outside of the new valve guide. Install the guide from the camshaft side of the head; use the special tool
to drive the guide in to the specified installed height. If you have all 12 guides to do, you may have to reheat the head.
