Valve Spring: Service and Repair

Special Tools:

Removal and Installation

1. Remove the camshaft roller followers.
2. Position the piston at top dead center.
3. Hold the valve in the cylinder head.
- Remove the spark plugs.
- Use a suitable tool to apply air pressure to the cylinder.





4. CAUTION: If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve to fall into the cylinder. If air pressure must be removed, support the valve prior to removal.

Using the special tool, remove the valve spring retainer keys, the valve spring and the retainer.
5. Inspect the components.

6. Note: Lubricate the parts with Super Premium SAE 5W-30 Motor Oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G prior to installing.

To install, reverse the removal procedure.
