2011 - 2013 QX56 AND M56; WHINE NOISE FROM ENGINE AREA
This bulletin has been amended. Several changes have been made to accommodate inclusion of M56 vehicles.
Please discard previous versions of this bulletin.
APPLIED VEHICLES: 2011- 2013 QX56 (Z62)
2011- 2013 M56 (Y51)
IF YOU CONFIRM:
A whine type noise is coming from the Bank 2 (B2) side of the timing chain system.
•
•
•
The noise is best heard from the high pressure fuel pump area.
The noise should increase in frequency with engine speed (RPM).
If the noise does not increase with engine speed, the timing chain system may not be the cause.
Refer to the appropriate section of the Electronic Service Manual (ESM) for further diagnosis.
ACTION:
Replace the B2 oil jet, both timing chains, both crankshaft sprockets, and all guides listed in PARTS
INFORMATION (page 2).
•
•
•
•
•
Always replace all seals, o-rings and gaskets.
Replace repair-related components as necessary.
For repair procedure, refer to SERVICE PROCEDURE (starting on page 4).
For QX56: Use Oil Jet Remover/Installer Kit J-51269 for oil jet removal, inspection, and installation.
For M56: Use Installer J- 51316 along with Oil Jet Remover/Installer Kit J-51269 for oil jet removal,
inspection, and installation.
NOTE: Essential Service Tool Oil Jet Remover/Installer Kit J-51269 was shipped April 2013 to all
Infiniti dealerships. Dealer non-vehicle accounts were charged $140.82 plus applicable taxes and
freight. Essential Service Tool Oil Jet Installer J- 51316 (for M56) was shipped August 2013 with
dealer non-vehicle accounts charged $99.85 plus applicable taxes and freight.
Oil Jet Remover/Installer Kit J-51269 contains:
¾ J-51269-1 Remover
¾ J-51269-2 Installer
¾ Gauge Pin – GO/NO-GO
IMPORTANT: The purpose of ACTION above is to give you a quick idea of the work you will be performing.
You MUST closely follow the entire SERVICE PROCEDURE as it contains information that is essential to
successfully completing this repair.
Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Infiniti dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
Remove Oil Jet
NOTE: For easier viewing, most pictures of repairs are shown on a removed QX56 engine (M56 is similar).
There is no need to remove the engine from either model vehicle to perform this repair.
1. Write down all radio station presets.

2. Disconnect both battery cables, negative cable first.
3. Remove both B1 and B2 timing chains and guides.
•
For both model vehicles: Refer to the B ENGINE > EM Engine Mechanical section of the ESM.
IMPORTANT: Follow all related Warnings, Cautions, and Notes in the ESM.
NOTE: If the crankshaft is determined to be 360° off from 0° TDC on #1 cylinder compression stroke
after removing the timing chain front cover, put the crankshaft pulley back on, and then rotate the
crankshaft 360° (when camshaft and crankshaft sprocket mating marks are aligned).

ITB13-009a
4. 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 4a - 4c 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:
•
If the gauge pin cannot be inserted
in the hole more than 3 mm, oil jet
replacement can be completed. Go
to Install Oil Jet below.
•
If the pin can be inserted in the hole
more than 3 mm, this repair cannot
be performed. Replace the “short
engine” (short block) assembly.
NOTE: The gauge pin comes with
essential tool J-51269 Oil jet
Remover/Installer Kit.
Figure 3
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.
•
See page 1 for tool information.

2. Mount the installer tool to the block.
•
With the oil jet inserted in the installer tool,
position the other end of the oil jet in the
block’s hole, and then align and finger tighten
the three bolts.
•
Finger tighten the bolts enough to position the
installer tool flush with the block.

For M56: Before tool installation, make sure
old sealant has been removed from the
mounting surface on the block.

bottoms out on top of the oil jet.
Hand tighten
4. Next, tighten the press bolt two (2) full turns.
•
Confirm the oil jet is centered and aligned.
5. With a suitable tool, hand tighten, but not overtighten, the three bolts.
•
Make sure the installer tool is flush with the
block.
