Oil Spray Jet: Testing and Inspection

Engine Oil Jet Inspection

1. Remove the oil jet, and inspect it as follows.
- Make sure that a 1.1 mm (0.04 in.) diameter drill will go through the nozzle hole (A) (1.2 mm (0.05 in.) diameter).

- Insert the other end of a 1.1 mm (0.04 in.) drill into the oil intake (1.2 mm (0.05 in.) diameter).
Make sure the check ball (B) moves smoothly and has a stroke of approximately 4.0 mm (0.16 in.).

- Check the oil jet operation with an air nozzle. It should take at least 200 kPa (2.0 kgf/cm2, 28 psi) to unseat the check ball.





2. Carefully install the oil jet. The mounting torque is critical.
