1. Remove the oil jet, and inspect it as follows. Make sure that a 1.1 mm (0.04 in.) diameter drillwill go through the nozzle hole (A) (1.2 mm
(0.05 in.) diameter).
 Insert the other end of a 1.1 mm (0.04 in.) drill into the oil intake (1.2 mm (0.05 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/cm , 28 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.

7. Clean both balancer shaft No. 2 journals and the
bearing halves with a clean shop towel, then install
the balancer shafts into the lower balancer shaft
holder.
8. Place one strip of plastigage across each No. 2 journal.
9. Reinstall the bearings and the upper balancer shaft holder, then tighten the bolts.
NOTE: Do not rotate the balancer shafts during inspection.
 After torquing, tighten the three 8 mm bolts extra 16 ° (K20Z3 engine). 10. Remove the upper balancer shaft holder and the
bearings again, and measure the widest part with
the plastigage. If the balancer shaft No. 2 journal oil
clearance is out-of-tolerance, install new bearings,
and recheck. If it is still out-of-tolerance, replace the
balancer shafts.
11. Align the punch mark on the rear balancer shaft in the center of the two punch marks on the front
balancer shaft, then install the balancer shafts on
the lower balancer shaft holder.
