With outer rotor inserted into pump body, press rotor to one side with fingers. If clearance between rotor and pump body is .014 inch or more, replace
oil pump assembly.

With inner rotor inserted into pump body, place a straightedge across face between bolt holes. If a feeler gauge of 0.004 inch can be inserted between
rotors and straightedge, replace oil pump assembly.
