Valve Guides
WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Manufacturer does not have a procedure for replacing valve guides.
To determine clearance between valve stem and guide, compare diameter of valve stem with inside diameter of valve guide. See CYLINDER HEAD and VALVES & VALVE SPRINGS tables under ENGINE SPECIFICATIONS. Valve guides can be reamed for .003" (.075 mm) oversize valves using Valve Guide Reamer (J-42096).
