Removal & Installation
- Heat cylinder head to 140°F (60° C) and press old guides out with drift (2818). To install, use intake guide drift (5027) and exhaust guide drift (5028) to press in new guides.
- Valve guides are available in standard size (no grooves) and 3 oversizes (1, 2 or 3 grooves). Ream oversize guides with proper reamer (5161, 5162, or 5163 respectively).
- Press in until drift contacts cylinder head to give proper height above cylinder head. Installed height for intake guide is .606-.614" (15.4-15.6 mm) and .705-.713" (17.9-18.1 mm) for exhaust guide.
NOTE:
Ensure that replacement guide is same size as old guide. At least 1980 lbs. (898 kg) force should be required to press in new guide; if not, head must be fitted with oversize guide.
NOTE:
Align marks as shown before installing timing belt.
