1. Engine Oil Jet and Bolt - Inspection





1. Inspect the oil jet and bolt as follows.

* Make sure that a 1.2 mm (3/64 in) diameter drill bit will go through the nozzle hole (A) (1.31 mm (0.0516 in) diameter).
* Insert the other end of a 1.9 mm (1/16 in) drill into the oil intake (2.0 mm (0.079 in) diameter). Make sure the check ball (B) moves smoothly and has a stroke of about 2.0 mm (0.079 in).
* Check the oil jet operation with an air nozzle. It should take at least 325 kPa (3.9 kgf/cm2, 47 psi) to unseat the check ball.

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