MX-5 Miata L4-1597cc 1.6L DOHC (1992)
HLA
Caution: The HLA must be reinstalled in the same position from which they were removed. If they are not, it can cause premature and uneven wear.
Note: Mark the HLA to show their original positions. Remove the HLA from the cylinder head.
1. Inspect the friction surfaces of each HLA for wear or damage. Replace the HLA if necessary - do not attempt to repair it.
2. Hold the bucket body and press the plunger by hand. If the plunger moves, it is defective. Replace the HLA - do not attempt to repair it.
