Valve And Spring Installed Height
WARNING: This page is about a different variant/trim than selected.
- Coat the valve stems (2) with clean engine oil and install the valves into the cylinder head.NOTE:
If the valves are being reused, reassemble them into their original locations.
- If the valves or valve seats have been refinished, check the valve tip height (5). If the valve tip height (5) exceeds the specification, grind the valve tip until it is within specification. Refer to Engine - Specifications . Make sure the measurement is taken from the cylinder head surface (7) to the top of the valve stem (2).
- If removed, install the spring seat (3) and valve guide seal (1) over the valve guide. Refer to SEAL(S), VALVE GUIDE, INSTALLATION .NOTE:
Ensure that the garter spring (2) is intact around the top of the valve guide seal (1). Number 5 cylinder exhaust valve guide seal shown in illustration, all other valves similar.
NOTE:If the valve springs are being reused, reassemble them into their original locations. Number 5 cylinder exhaust valve spring shown in illustration, all other valves similar.
- Install the valve spring (2) and valve spring retainer (1).
NOTE:
Number 3 cylinder intake valve spring compression shown in illustration, all other valves similar.
- Compress valve springs (3) with the Valve Spring Compressor Adapter (special tool #10224, Adapter, Valve Spring) (2) mounted in the Valve Spring Compressor (special tool #C-3422-D, Compressor, Valve Spring) (1). Install the retaining locks (4) and release the valve spring compression.
- If the valves or valve seats have been refinished, check the installed height of the valve springs (4). If the installed valve spring height (4) is greater than 40.0 mm (1.575 in.), install a second spring seat (8) in the head counterbore under the valve spring seat (8) to bring the spring height back within specification. Make sure the measurement is taken from the top of spring seat (6) to the bottom surface of spring retainer (1).
