Radial clearance
WARNING: This page is about a different car, the 2010 Suzuki Kizashi. However, it is still accessible from the selected car via links, so may be relevant.
Check radial clearance between outer rotor (2) and oil pump housing (3) using feeler gauge (1).
If clearance is out of specification, replace oil pimp assembly.
