Oil Jet Replacement (as needed)
1. Remove the B2 oil jet using Remover Tool J-51269-1 (see Figure 1).
a. Install the remover tool onto the oil jet and flush against the engine block (see cutaway, Figure 1).

Align the hex bolts to contact the oil jet’s flat and worn sides.

Slide the threaded shaft all the way in the outer housing.
b. Hand tighten both hex bolts with an Allen wrench.

Tighten enough to keep the remover tool from slipping, but no more.

c. Hold the remover tool’s outer housing
with a wrench while turning the nut
clockwise.

This procedure will extract the oil jet
from the block.

If the oil jet is not extracted on the
first attempt, steps 1a - 1c will need
to be performed a second time.

d. Determine if oil jet replacement is
possible by inserting the gauge pin into
the block’s hole:
NOTE: The gauge pin comes with
essential tool J-51269 Oil jet
Remover/Installer Kit.

If the gauge pin cannot be inserted
into the hole more than 3 mm, oil jet
replacement can be completed. Go
to Install Oil Jet below.

If the pin can be inserted into the hole
more than 3 mm, this repair cannot
be performed replace long engine.

IMPORTANT: Powertrain Call Center must be called for preauthorization first before
replacing a long engine (long block). Please see details starting on page 14.
Install Oil Jet
1. Insert the new oil jet into the installer tool.

For QX56, use tool J-51269-2.

For M56, use tool J- 51316.

bottoms out on top of the oil jet.
Hand tighten
4. Next, tighten the press bolt two (2) full turns.
5. With a suitable tool, hand tighten, but not overtighten, the three bolts.

Press bolt
Bolts should only be tight enough to seat the
installer tool to the block.

If a new oil jet pin can be inserted into the hole more than 3 mm and indicates long engine replacement is
required.
1. Complete the PCC Preauthorization Form in ASIST.
13/14
ITB16-015a
2. Attach the required video (15 seconds or less) of oil jet pin test and vehicle VIN to the Preauthorization
Form.

Failure to submit a continuous video showing evidence of loose oil jet hole and the VIN will cause
immediate denial of request for long engine replacement.
3. Call the PCC for authorization at 800-973-9992 (opt 1).
IMPORTANT: Make sure the video has a clear image of the VIN on the F.M.V.S.S.
