Engine Oil Jet Inspection

  1. Remove the oil jet , and inspect it as follows.
    • Make sure that a 1.2 mm (0.05 in.) diameter drill will go through the nozzle hole (A) (1.31 mm (0.052 in.) diameter).
    • Insert the other end of a 1.9 mm (0.07 in.) drill into the oil intake (2.0 mm (0.08 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 340 kPa (3.5 kgf/cm 2 , 50 psi) to unseat the check ball.
    NOTE: Replace the oil jet assembly, if the nozzle is damaged or bent.
  1. Carefully install the oil jet. The mounting torque is critical.
    Specified Torque:
    16 N·m (1.6 kgf·m, 12 lbf·ft)
