Valve Clearance Adjustment
WARNING: This page is about a different car, the 1995 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Valve clearance is nonadjustable, but clearance can be checked to determine if worn components exist.
- Rotate camshaft so base circle of camshaft lobe is positioned on valve to be checked. Using Valve Spring Compressor (T88T-6565-BH), apply pressure on cam follower until lash adjuster is fully collapsed.
- While holding lash adjuster in fully collapsed position, use feeler gauge to measure clearance between base circle of camshaft and camshaft follower. See COLLAPSED VALVE LIFTER CLEARANCE table.
- If clearance is not within specification, inspect camshaft follower for damage. If camshaft follower is not damaged, check for sticking valve, or worn valve spring or camshaft lobe(s). If components are okay, check for defective lash adjuster. Replace components as necessary.
