REMOVAL & INSTALLATION



Valve spring removal and installation is part of the "Valves, Removal and Installation" procedure covered in this section.

INSPECTION



Valve spring squareness, length and tension should be checked while the valve train is disassembled. Place each valve spring on a flat surface next to a steel square. Measure the length of the spring, and rotate it against the edge of the square to measure distortion. If spring length or distortion exceeds specifications, replace the spring.
