Hydraulic Lash Adjuster (HLA) Inspection

HYDRAULIC LASH ADJUSTER (HLA) INSPECTION
1. Measure the diameter of each HLA bore.

Standard diameter
16.018-16.057 mm (0.63063-0.63216 in)

2. Measure the diameter of each HLA.

Standard diameter
15.988-16.000 mm (0.62945-0.62992 in)

3. Calculate the clearance between the HLA and the related HLA bores.
^ If the clearance exceeds the maximum clearance, replace the cylinder head or the HLA.

Standard clearance
0.018-0.069 mm (0.0008-0.0027 in)
Maximum clearance
0.16 mm (0.0063 in)
