Engine Oil Jet Inspection

1.Remove the oil jet, and inspect it as follows.

  • Make sure that a 1.7 mm (0.07 in.) diameter drill will go through the nozzle hole (A) (1.8 mm
    (0.07 in.) diameter).
  • Insert the other end of a 3.1 mm (0.12 in.) drill into the oil intake (3.2 mm (0.13 in.) diameter). Make sure the check ball (B) moves smoothly and has a stroke of about 2.0 mm (0.08 in.).
  • Check the oil jet operation with an air nozzle. It should take at least 120 kPa (1.2 kgf/cm2, 17 psi) to unseat the check ball.

NOTE: Replace the oil jet assembly, if the nozzle is damaged or bent.


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

Specified Torque: 22 N·m (2.2 kgf·m, 16 lbf·ft)
