Oil Jet Inspection

Remove the oil jet, and inspect it as follows.
- Make sure that a 1.5 mm (0.059 in.) diameter drill will go through the nozzle hole (A) (1.6 mm (0.062 in.) diameter).
- Insert the end of a 1.1 mm (0.043 in.) drill into the oil intake (1.2 mm (0.047 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.
  NOTE: Replace the oil jet assembly if the nozzle is damaged or bent.

The mounting torque is critical. Be very precise when installing the oil jet.
Torque: 16 N.m (1.6 kgf.m, 12 lbf.ft)
