Inspection
NOTE: Refer to the Exploded View if needed during this procedure.
1. Remove the screws from the pump housing, then separate the pump housing and the cover.
2. Check the inner rotor-to-outer rotor radial clearance between the inner rotor (A) and the outer rotor (B). If the inner rotor-to-outer rotor clearance exceeds the service limit, replace the oil pump assembly.

6. Apply liquid gasket (P/N 08717-0004, 08718-0003, 08718-0004, or 08718-0009) to the engine block mating surface of the oil pump and to the inside edge of the threaded bolt holes. Install the component within 5 minutes of applying the liquid gasket.
NOTE:
- Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A).
- If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
- If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply the new liquid gasket.
7. Apply a light coat of new engine oil to the lip of the crankshaft oil seal, and to the new O-ring (A).
8. Install the dowel pins (B), then align the inner rotor with the crankshaft, and install the oil pump (C).
NOTE:
- Wait at least 30 minutes before filling the engine with oil.
- Do not run the engine for at least 3 hours after installing the oil pump.
9. Clean the excess oil off the crankshaft, and check that the oil seal lip is not distorted.
10. Install the oil strainer (D) with a new O-ring (E).
11. Install the oil pan Engine Oil Pan Installation.
12. Install the oil filter base/oil filter assembly, with a new O-ring (J35Z2 engine), or rocker arm oil control solenoid/oil filter assembly, with a new rocker arm oil control solenoid filter (J35Z3 engine).
13. Install the timing belt drive pulley to the crankshaft:
- J35Z2 engine Service and Repair
- J35Z3 engine Service and Repair
14. Support the engine with a jack and a wood block under the oil pan.
