B. Inspect rotor tip clearance
Using a feeler gauge, measure the clearance between the
drive and driven rotors.
Standard tip clearance:
2JZ–GE
0.310–0.490 mm (0.0122–0.0193 in.)
2JZ–GTE
0.056–0.326 mm (0.0022–0.0128 in.)
Maximum tip clearance:
2JZ–GE
0.53 mm (0.0209 in.)
2JZ–GTE
0.40 mm (0.0157 in.)
If the tip clearance is greater than maximum, replace the ro-
tors as a set.

C. Inspect rotor body clearance
Using a feeler gauge, measure the clearance between the
driven rotor and pump body.
Standard body clearance:
2JZ–GE
0.100–0.175 mm (0.0039–0.0069 in.)
2JZ–GTE
0.080–0.135 mm (0.0031–0.0053 in.)
Maximum body clearance:
2JZ–GE
0.20 mm (0.0079 in.)
2JZ–GTE
0.16 mm (0.0063 in.)
If the body clearance is greater than maximum, replace the
rotors as a set. If necessary, replace the oil pump assembly.

D. Inspect rotor side clearance
Using a feeler gauge and precision straight edge, measure
the clearance between the rotors and precision straight
edge.
Standard side clearance:
2JZ–GE
0.030–0.090 mm (0.0012–0.0035 in.)
2JZ–GTE
0.020–0.065 mm (0.0007–0.0026 in.)
