CAUTION
When a valve spring is compressed, the valve may drop out of the cylinder head.
Do not allow the valves to drop onto a hard surface. Failure to observe this
caution may result in damage to the valves.
1. Compress the intake valve spring (see Figure 2).
2. Remove the following components: valve keeper, spring retainer, spring, valve stem seal,
washer, and intake valve (see Figure 1). Discard the valve stem seal.
3. Tag the intake valve and the other components so they can be reinstalled in the same location.
