SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
IMPORTANT NOTES: The service procedures for the steps involving valve spring replacement
have been revised for this Product Campaign. These specific procedures, involve the use of a set of
special tools, carefully designed to help Technicians perform this campaign with increased efficiency
while reducing the amount of engine disassembly. Proper use of these special tools is critical to
achieve the required results. Some portions of the overall procedure (e.g. engine assembly removal
and reinstallation) are unchanged. For those portions of this procedure, always refer to the applicable
Service Manual and review the full requirements of the steps being performed. The Service Manual
procedures contain information critical to performing an effective repair the first time and every
time. This includes but is not limited to: important SAFETY precautions, proper inspection criteria,
other necessary special tools and required processes needed for a complete and lasting repair.
The Service Procedure for this campaign will be divided into 3 sections:
•

Section 1: Special Tools

•

Section 2: Valve Spring replacement for 2.0L “FA” engine used in BRZ

•

Section 3: Valve Spring replacement for 2.0L “FB” engines used in Impreza and Crosstrek.

The major differences between procedures can be summarized as follows:
For FA engine:
•

Timing cover, timing chain, camshaft (and related components) removal is required for
access.

•

The valve spring replacement tools consist of one remover and one installer.

Continued...
Bulletin Number: WTY-84R; Revised: 05/06/20

Page 3 of 42

For FB engine:
•

Timing cover (and related components) removal is NOT required for access.

•

The valve spring replacement tools consist of a set of four different spring compressor tools,
two retainer / keeper re-installation tools and a “bridge” framework to properly position each
tool.

Both the FA and FB procedures require removal of the engine assembly.
NOTE: If the engine has been removed from the vehicle for any warrantable concern in addition to
performing WTY-84, see the CLAIM REIMBURSEMENT AND ENTRY PROCEDURES section
on pg. 28 for instruction on how to properly submit the claim.

VERY IMPORTANT: When using the above spring compressor and installation tools, use ONLY
the tool specified for the specific task being performed. NEVER ATTEMPT TO USE THESE FBSPECIFIC TOOLS TO PERFORM THIS PROCEDURE ON A FA ENGINE (to avoid removing
the front cover and camshafts) OR A 2015MY or later FB ENGINE AS DOING SO WILL
SEVERELY DAMAGE THEM. Although some of these tools look very similar to each other, there
are significant design differences in each which make them specific for each function. This is why
they have the paint markings and alpha-numeric identification information etched onto them. More
detail on each tool’s specific function will be provided later in this bulletin.
Section 2: FA Engine Procedure:
TIPS:
• Road test the vehicle before disassembly to confirm the engine operates as designed with no
abnormalities (e.g. smoke from exhaust, engine noise, fluid leak(s), A/C system operation,
etc.).
•

Check for any DTC(s).

•

Check for any vehicle modifications. If found, document them using the existing process
outlined in the Claims Policies and Procedures section 8.4.45 “Procedures for Assessment,
Documentation, and Notification of Non-Warrantable Repairs” using the “Vehicle
Modification and Accident Damage Report” found on Subarunet under Service-Technical /
Forms / Downloads.

•

Note and review any items needing attention with the customer BEFORE proceeding.
Having the customer initial these item by item on the repair order is highly recommended.

•

Contact the SOA Techline immediately to review any concerns believed to be impeding or
preventing proper completion of this recall. There should be very few if any cases where this
would be necessary. A severe example of an impediment would be if the wrong specification
engine is found to be installed. Nearly all aftermarket modifications can be worked around or
removed to allow valve spring replacement to proceed.

•

Contact the SOA Claims Team should removal and / or reinstallation of these customer
modifications require significant additional time.

•

Open both door windows before disconnecting the battery to avoid weatherstrip damage.

•

Remove the fuel pump fuse. Start and run the vehicle until it stalls to relieve fuel pressure.

•

Remove the fuel cap to release any vapor pressure inside the fuel tank and to prevent fuel
spray when disconnecting fuel lines.

•

Record the customer’s radio station presets (and Navigation System Favorites if applicable)
then disconnect the battery negative cable from the battery terminal.

•

Separate the exhaust manifold assembly from the front exhaust pipe and remove the manifold
from the vehicle. The manifold to cylinder head gaskets are included in the Parts Kit but the
front pipe gasket, p.n. 44011AG000 as mentioned in the Parts
Information section is not.

•

Evacuate the A/C system. Remove the discharge (highside) line from the compressor. Always protect any exposed
connections from contamination while the system is open.

•

Secure the compressor to the hood hinge so it is out of the
way as shown in the illustration . Be careful to not kink or
twist the attached hose assembly.

IMPORTANT NOTE: In a limited number of cases, some vehicles may have had prior repairs
which included valve spring replacement. Should you encounter a vehicle that appears to have had
valve springs installed of the type described in these procedures, whether through engine assembly,
cylinder head, or simply valve spring replacement as part of a prior repair, contact the SOA Claims
Team to review any findings or concerns BEFORE proceeding further with this WTY-84R spring
replacement campaign. The SOA Claims Team will work to provide guidance on how best to
proceed and claim for these limited cases.
1) After draining the engine oil and coolant, remove the engine assembly following the existing
procedures in the applicable Service Manual.
•

On A/T models, use the special support tool p.n. 18632AA010 to support the transmission
while the engine is removed. VERY IMPORTANT: NEVER use a jack or a block of
wood on the oil pan of the A/T
assembly as valve body damage
can occur easily. On M/T
models, a block of wood can be
used to support the transmission.

•

Also on A/T models, ALWAYS
install the torque converter
stopper tool to keep the converter
secured in the transmission when
separating the engine.

2) Secure the engine assembly to the engine stand using the four (4) bolt locations as shown below.
Before tightening any of the bolts, position the engine on the stand so the crankshaft centerline
is as close as possible to being aligned with the center pivot point of the engine stand. This will
make the engine easier to rotate when switching from side to side.

3) Remove both LH and RH intake manifold protectors.
4) Remove all the ignition coils and spark plugs. Leave the coils
connected to the engine wiring harness.
5) Secure the ignition coils and harnesses to the intake manifold
to keep them out of the work space.
6) Remove both LH and RH valve covers. Apply Silicone Gasket
Remover spray and allow it to “soak” while performing other
steps of the procedure. This will make removing the original
sealer considerably easier.
7) Measure and record the cam clearances following the procedure in the applicable Service Manual.
Continued...
Bulletin Number: WTY-84R; Revised: 05/06/20

Page 7 of 42

IMPORTANT NOTES: The purpose for performing these cam clearance measurements is to
compare the “before” and “after” values and confirm there was no change.
•

If the clearances are out of specification, obtain the required shims for installation prior to
reassembly.

•

If the clearances are all within specification at this point but after reassembly, some are
found to be out of specification, it is likely some of the shims were miss-positioned during
reassembly. CAREFULLY Re-adjust as necessary to insure all clearances are within the
following specifications:
Standard values (cold engine):  
○ INTAKE: 0.10 to 0.16 mm {0.0039 to 0.0063 in.}  
○ EXHAUST: 0.21 to 0.27 mm {0.0083 to 0.0106 in.}

8) CAREFULLY remove the timing chain cover, timing chain and all related components following
the existing procedures in the applicable Service Manual.

9) Apply a reference mark to the face of the removed crankshaft pulley using touch-up paint or a
grease pencil adjacent to the locating pin hole as shown below.

TIPS: Stand the removed timing cover up as shown to allow any remaining oil to drain from the
internal passages. This keeps residual oil from potentially contaminating fresh sealer applied to the
cover at reassembly (which could cause a leak or a possible comeback).

Use of aerosol Subaru Silicone Gasket Remover (p.n. SOA868V9175)
along with white plastic razor blades and / or a sharpened plastic
trim removal stick to use as a non-marring scraper will make this
critical part of the procedure easier. Applying the Gasket Remover
spray and allowing it to “soak” while performing other steps
