Oil Spray Jet: Testing and Inspection
Engine Oil Jet Bolt Inspection
1. Remove the oil jet bolt See: Service and Repair.
2. Inspect the oil jet bolt as follows.
-
Make sure that a 0.6 mm (0.024 in) diameter drill will go through the oil intake (0.7 mm (0.028 in) diameter). Make sure the check ball (A)
moves smoothly and has a stroke of about 4.0 mm (0.157 in).
-
Check the oil jet bolt operation with an air nozzle. It should take at least 120 kPa (1.22 kgf/cm2, 17.4 psi)to unseat the check ball.
