Valve Springs
WARNING: This page is about a different variant/trim than selected.
- Measure valve spring installed height from surface of cylinder head spring pad to underside of spring retainer. If installed height is greater than specification, a shim can be installed between cylinder head and valve spring to obtain correct height. See VALVES & VALVE SPRINGS table under ENGINE SPECIFICATIONS.
- Inspect valve spring free length and pressure. Replace valve spring if free length and pressure are not within specification. See VALVES & VALVE SPRINGS table.
CAUTION:
DO NOT install valve spring spacers unless necessary. Using more spacers than required can result in spring breakage or worn camshaft lobes.
