- Inspect the face of the lifter for excessive wear (1). The lifter face should be highly polished with no visible grooves.
- Using a marker, mark the location of each valve lifter. Use the following coding for marking the valve lifters:
- Prepare a clean piece of cardboard to place the lifters on.
- Remove the lifters and place them on the cardboard.
- Secure the cardboard and the followers in order to prevent damage or contamination.
| • | A large circular pattern with deep grooves starting at the center and moving outward (1) indicates the lifter is not wearing correctly. This pattern most likely is caused by improperly machined or worn camshaft lobes. |
| • | The lifter must be replaced if wear is evident. |
| • | Cylinder number |
| • | Follow the cylinder number with I for intake or E for exhaust |
| • | Valve number, 1 or 2, from the front of the engine |
| • | For example, 3E1 would be defined as number three cylinder, first exhaust valve from the front of the engine. |
