Final answer:
All of the following oil pump measurements should be performed with a feeler gauge, except for measuring the pump cover flatness.
Step-by-step explanation:
All of the following oil pump measurements should be performed with a feeler gauge EXCEPT:
- Measure pump cover flatness with a feeler gauge positioned between a straightedge and the cover.
- Measure the clearance between the inner rotor and the housing.
- Measure the clearance between the inner and outer rotors with the rotors installed.
- Measure the clearance between the top of the rotors and straightedge positioned across the top of the oil pump.
So, the oil pump measurement that should not be performed with a feeler gauge is measuring the pump cover flatness with a feeler gauge.
