If it doesn't, replace the valve or the entire oil pump.
2. Using a feeler gauge, measure the radial clearance between the driven rotor and the pump housing.
Rated Clearance:
- 2C. 2S-T - 0.10-0.17 mm
- 3S-FE, 3S-GE, 4S-FE - 0.10-0.26 mm
- 4A-FE, 7A-FE - 0.08-0.18 mm
- 5E-FE - 0.10-0.21 mm
Maximum allowable - 0.20 mm
3. Using a feeler gauge, measure the radial clearance between the male and female rotor lugs.
Nominal:
- 2C, 2C-T, 5E-FE - 0.080-0.160 mm
- 3S-FE, 3S-GE and 4S-FE - 0.040-0.150mm
- 4A-FE - 0.060-0.180 mm
- 7A-FE - 0.025-0.085 mm
Maximum allowable:
- 2C, 2C-T, 3S-FE, 3S-GE and 4S-FE - 0.20 mm
- 4A-FE, 7A-FE - 0.35mm
- 5E-FE - 0.25 mm
4. Using a precision ruler and feeler gauge, measure the end clearance between the rotors and the housing wall:
Nominal:
- 4A-FE - 0.025-0.075 mm
- 5E-FE - 2.97-2.91 mm
- 7A-FE - 0.025-0.085 mm
Maximum allowable:
- 4A-FE, 7A-FE - 0.10 mm
- 5E-FE - 2.90mm

If either gap is greater than maximum, replace both rotors. Replace the entire pump if necessary.
