- Coat valve stems with clean engine oil and insert in cylinder head.
- Install new valve stem seals (3) on all valves using an appropriate sized socket to seat the seal/spring seat. The valve stem seals should be pushed firmly and squarely over valve guide.
- Install valve springs (2).
- Install keepers in retainer and place on valve spring.
- Using metric valve keeper tool such as Snap-on® GA317 (or equivalent) installer (2) and remover (1) as a handle, push downward to install keepers.
- Check the valve spring installed height B after refacing the valve and seat. Make sure measurements are taken from top of spring seat to the bottom surface of spring retainer. If height is greater than 38.75 mm (1.525 in.), install a 0.762 mm (0.030 in.) spacer under the valve spring seat to bring spring height back within specification.
