1. INSPECT OIL PUMP RELIEF VALVE

INSPECT OIL PUMP RELIEF VALVE

(a) Coat the relief valve with engine oil and check that it falls smoothly into the valve hole under its own weight.

If the valve does not fall smoothly, replace the relief valve. If necessary, replace the oil pump assembly.

2. INSPECT OIL PUMP ROTOR SET

 INSPECT OIL PUMP ROTOR SET

(a) Install the rotors to the timing chain cover with the rotors' marks facing outward. Check that the rotors rotate smoothly.

INSPECT OIL PUMP ROTOR SET

(b) Check the tip clearance.

(1) Using a feeler gauge, measure the clearance between the drive and driven rotors, as shown in the illustration.

Tip clearance

If the clearance is greater than the maximum, replace the drive and driven rotors.

INSPECT OIL PUMP ROTOR SET

(c) Check the side clearance.

(1) Using a feeler gauge and precision straightedge, measure the clearance between the rotors and precision straightedge, as shown in the illustration.

Side clearance

If the side clearance is greater than the maximum, replace the timing chain cover.

INSPECT OIL PUMP ROTOR SET

(d) Check the body clearance.

(1) Using a feeler gauge, measure the clearance between the timing chain cover and driven rotor, as shown in the illustration.

Body clearance

If the body clearance is greater than the maximum, replace the timing chain cover.
