INTRODUCTION
This bulletin announces information regarding a major change to the repair procedures previously
outlined in Service Bulletins 02-143-13R, 02-144-13R and 02-145-13R. These bulletins provided
a repair procedure for the replacement of the piston rings to address verified concerns of unusual
engine oil consumption. Vehicles confirmed as having this condition which are within the supplied
VIN ranges will no longer be repaired with piston ring replacement. The revised repair procedure
to address verified unusual oil consumption concerns on these specific vehicles will consist of
replacing the engine short block assembly.
It is critical to understand the nature of the concern as reported by the customer and to confirm the
actual condition prior to attempting repairs. Some oil consumption can and should be expected
as a by-product of engine operation even where no concern exists. Failure to recognize this and
correctly diagnose the condition presented can result in unnecessary repairs. For example: a vehicle
which is presented with a report of a low engine oil level (as read on engine dipstick/ gauge or
indicated by illumination of the low engine oil level warning lamp), which is at or near the time /
mileage of the next service interval (based upon the date / mileage of the most recent oil change),
is not representative of unusual oil consumption. The information supplied in this bulletin is
only applicable to vehicles within the specific production ranges of this publication exhibiting the
condition(s) previously described.
IMPORTANT: Read and understand this bulletin COMPLETELY before starting an oil
consumption test or initiating any repairs.
Concerns related to a possible oil consumption condition are generally initiated when the customer
believes the engine oil level on the dipstick has dropped since the last time it was checked or when
the low oil lamp illuminates. These types of complaints by themselves do not directly indicate
a concern with the vehicle exists. It is important to understand all the factors involved in order
to make a sound decision regarding whether or not a repair is required or if an oil consumption
test should even be started. When speaking with customers about a reported or suspected oil
consumption concern, always keep the following in mind:

Some engine oil will always be consumed as part of normal engine operation. How much and
when it is consumed varies according to manufacturing tolerances, wear, and vehicle usage patterns.
With the extended service intervals commonly used for today’s engines combined with one or more
of the conditions listed below, typical engine oil consumption may require adding engine oil in
between scheduled maintenance intervals:
•
When the engine is new and within the break-in period (during the first 1000 miles of
operation)
•
When the engine oil being used is of lower quality (other than “Energy or Resource
Conserving” API Classification SM or SN or ILSAC, look for the starburst design with
GF-4 or GF-5)
•
When the incorrect oil viscosity is used (viscosity other than 0W-20 in
the case of these specific vehicles)
•
When engine braking is employed (use of the transmission’s gear ranges
to decelerate while using the engine to apply resistance)
•
When the engine is operated at high engine speeds (continually or under
frequent, hard acceleration)
•
When the engine is operated under heavy loads (frequent carrying of
heavy cargo, passengers or trailer towing)
•
When the engine idles for long periods of time (may be related to frequent
use of a remote engine start system)
•
When the vehicle is operated in stop and go and/or heavy traffic situations
•
When the vehicle is used under severe temperature conditions (cold or hot)
•
When the vehicle accelerates and decelerates frequently
Under these or similar operating conditions, the oil level should be checked more frequently. The
engine oil and filter may also need to be changed more often. As per the Owner’s Manual, engine
oil consumption under these conditions may be as high as 1 quart per 1200 miles.
As related information, the low oil level warning light (on models so equipped) is designed to
illuminate when the engine oil level in the sump drops below approximately 4 quarts with the engine
not running (engine is 1.1 quarts low on oil) and 2.4 quarts when the engine is running. While this
may seem very low, keep in mind that oil remains suspended in the engine while running and will
not fully drain back until the engine has been shut off for at least 5 minutes. In some rare cases, this
light may illuminate with more oil present when the engine is running due to specific road or driving
conditions such as repeated hard acceleration/ deceleration, tight turning, driving on undulating
roads. In these cases, the light will generally reset on its own once the actual level is determined
to be above the illumination threshold. However, this may take some time as certain driving
parameters must be met for the system to self-correct. As long as the oil level has been checked and
adjusted (if necessary), the immediate concern has been addressed. If the lamp does not extinguish
on its own after some time and the oil level remains full, an inspection of the circuit and components
should be performed. See Section 3 of the Owner’s Manual for more information on the oil level
warning system. See Service Procedure to reduce false illumination of low oil level warning
lamp (on models so equipped) later in this bulletin for instructions on how to address customer
concerns where the low engine oil level warning lamp illuminates when the engine oil level is either
full or nearly full.

SERVICE PROCEDURE / INFORMATION
Before starting any repairs, the first step is to always confirm the customer’s complaint. It is
critical to get as much information from the customer as possible to help you make the most accurate
diagnosis.
•
Review all the available service and repair history along with any other records the customer
can provide to establish whether or not the vehicle has been properly maintained.
•
Perform a thorough visual inspection to make sure there are no external oil leaks that could
be contributing to the condition.
•
It is also very important to not overlook the engine’s PCV system and to confirm it is
operating properly. Check the air filter assembly and throttle body / intake manifold for any
excessive oil residue which could be an indicator of a sticking or failed PCV valve.
NOTES:
•
An oil consumption test will need to be completed to determine the proper course of action.
There is a specific procedure and Oil Consumption Test form which must be completed. See
Subarunet \ Service \ Forms for the latest test form. Always print the latest form anytime a
new test is started.
•
Where applicable, available reprogramming to reduce the possibility of false low engine oil
level warning lamp illumination must be installed. See Service Procedure to reduce false
illumination of low oil level warning lamp (on models so equipped) later in this bulletin
for further instructions. This must be completed at either the start or end of the consumption
testing regardless of the final outcome.
Continued...
Bulletin Number: 02-157-14; Revised: 09/08/14
Page 4
IMPORTANT: At the start of the Oil Consumption Test Form, specific information regarding what
prompted (reason for) the testing must be collected. Once this questionnaire section of the form is
completed, it must be faxed to 856-488-3199. Upon completion of the actual consumption test, the
remainder of the form must be completed and faxed AGAIN to 856-488-3199. This information is
being collected for quality assurance purposes only. You will not receive any response from these
submissions. This is NOT an authorization process. Proceed with any necessary testing or repairs as
indicated by the information provided in this service bulletin, the Oil Consumption Test form results,
Subaru’s Claims Policies and Procedures, and your evaluation of the actual condition presented based
upon your review of all three areas. Keep in mind, these repairs should only be completed when
unusual oil consumption has been confirmed.
Before initiating the consumption test, all basic checks must be completed. These include (but are not
limited to): confirming the actual oil level, noting if any oil has been added prior to this visit and how
much, checking for any external leaks, confirming PCV operation, and verifying that a consumption
test has not already been started or completed previously. Always use the latest Oil Consumption
Test form form found on Subarunet in the Service Forms area. Follow the instructions outlined on the
form.
NOTE: The oil and filter change is only necessary if no prior consumption test has been completed
or is already in process. There is no need for duplicate or repeat testing. One-time documented results
are all that is required to move forward with these repairs. Always close the repair order on the day
the oil change has been completed and submit the claim for the oil consumption test using the coding
provided at the end of this bulletin. Indicate “Oil Consumption Test” in the comments field / box
when entering your claim. DO NOT hold the repair order open until the vehicle returns. Have the
customer drive the vehicle then return for inspection when any of the following have occurred:
•
At least 1200 miles have elapsed
•
When the low engine oil level warning lamp illuminates (when equipped)
•
When the oil level reaches the lower hole in the dipstick/ gauge (as determined by the
customer).
The customer should be advised to not add oil unless there will be a significant delay before they can
return for inspection once a low oil condition occurs. A one-time check of the oil consumption by the
retailer is all that is needed to establish if the condition outlined in this bulletin applies.
SPECIFIC SERVICE PROCEDURES
The following information is provided to underscore service procedures specific to the repairs
outlined in this bulletin. They are not meant to represent the entire repair process from start
to finish. The procedures provided here are specific to certain steps in the overall process.
In some cases, they will differ greatly from the Service Manual instructions and should be
followed in place of the Service Manual for these specific areas only. For the balance of the
repair procedure, refer to the Service Manual. It is highly recommended to review all of the
Service Manual procedures for short block replacement then review these specific procedures to
become familiar with the differences.

•
When draining the engine oil, do not remove the engine oil filter. Leave the existing oil filter
in place through engine disassembly, reassembly, installation and initial startup after engine
reassembly.
•
When removing the engine, there is no need to remove the transmission case cover (CVT
only) or to disconnect / disturb any of the transmission harness connectors. While raising
the transmission with the service jack placed under the front differential as shown in the
illustration below, only raise it enough to access and remove the engine mounting
hardware. Raising it too high can push the transmission up into the bulkhead / transmission
tunnel and possibly cause damage.
•
When removing the CVT fluid cooler (if equipped), leave it attached to its mounting bracket
and remove as an assembly (3 bolts) from the transmission. Disconnect just the engine
coolant hoses from it and do not disturb the 2 short CVT fluid lines. Hook one of the cooler’s
mounting bracket “ears” behind the bulkhead harness as shown in the photo below to keep
the cooler assembly out of your way. Use a shop cloth between the “ear” and the bulkhead
harness to prevent any chafing.

•
To make separating the transmission (CVT) from the engine easier, there is a pry relief
shown below in the machined mounting surface of the transmission case near the engine
number. Use caution when applying any prying pressure and avoid twisting the tool to
prevent case damage.
•
Once the engine is removed, if you are using a generic engine stand (preferable since engine
rotation is necessary), use the four mounting holes on the engine block shown below to
mount it. NOTE: Do not use the mounting studs in the upper oil pan.

•
When removing the intake manifold, as shown in the photos below, leave the TGV
assemblies attached to the upper intake, remove the 2 nuts holding the EGR tube to the water
pipe then remove the complete assembly from the cylinder heads as a unit.
•
There is no need to remove the oil dipstick tube or the original oil filter from the front chain
cover. While the cover is removed, store it face (front side) down to minimize the chances of
damaging the machined sealing surface on the block / head side. Also, don’t use it as a tray
to store other removed parts.
•
IMPORTANT: After all 32 bolts securing the chain cover are removed, be EXTREMELY
careful where you pry and what you pry on to break the silicone sealant’s bond. The photos
below show an example of where NOT to pry. In this case, the cam cap became cracked
requiring a complete cam carrier replacement. Patience is the key!

Refer to the instructions found in the Technician Reference Booklet (TRB) for Technical
Training Module 105: “Chain Driven Valve Train Boxer Engines” when removing and
reassembling the timing chain components. The photos and instructions found in the TRB
and provided below have shown to be preferable to those provided in the Service Manual.
•
The timing chains driving the camshafts are identical and are provided with colored
identification links used to align with component timing marks. Chain guides are also
identical for the left and right banks. It is recommended to mark the parts as they are
removed. Return them to their original positions during reassembly to maintain established
wear patterns. Colors used for the identification links will vary.
•
Begin timing chain removal by positioning the crankshaft keyway at the 6:00 position. The
RIGHT bank intake camshaft timing mark (Δ) must be at 6:00 with right bank exhaust timing
mark at 12:00 (camshafts will be unloaded).

Compress the chain tensioner by hand, insert a pin through the lever into the access hole
to lock the plunger in place then remove the 2 bolts, tensioner, guides and right side timing
chain.

After turning the crankshaft CLOCKWISE, repeat the procedure for the LEFT side with the
timing marks (Δ) positioned as shown below. Align the crank sprocket keyway with RH
chain dowel pin (shown in red below).

Compress the chain tensioner by hand, insert a pin through the lever into the access hole to
lock the plunger in place then remove the 2 bolts, tensioner, guides and the left side timing
chain.
•
After the left chain is removed, turn the crankshaft in a COUNTER CLOCKWISE direction
until the timing mark on the crankshaft sprocket (NOT the keyway) is back to the 6:00
position as shown below. This positions all the pistons away from TDC and prevents
accidental contact between the pistons and valves.

•
Before proceeding, it is best to rotate the engine on the stand 90 degrees so it is vertical with
one cylinder head facing up (head gasket surface horizontal).
•
Remove the rocker cover then the cam carrier from the head that is “up”. Do not disturb the
small camshaft end cap covers. Remove the cam carrier with the camshafts as an assembly.
At this point, the rest of the valve train is sitting loose on the cylinder head. It is imperative
all the rockers, selective lash caps and rocker pivots are returned to their original
positions on the cylinder head during reassembly. TIP: An egg carton for each head
makes a perfect organizer tray. Make sure to mark it as necessary (front, intake, exhaust) to
eliminate any mixing of parts.
•
Loosen the cylinder head bolts in proper order, remove the head, then flip the engine over and
repeat the same steps for the opposite side.
•
It is very important to take the time necessary to thoroughly clean the old silicone sealer from
all the removed components before reassembly. It is a good idea to clean the surrounding
areas then use tape to block off any oil passages in the front cover and cam carriers so any
small bits of removed silicone debris are kept from entering the oil passages and possibly
causing problems after reassembly. Once all the old sealer has been removed, remove any
block-off tape, rinse out any oil passages thoroughly with brake cleaner and shop air.

•
Don’t forget to clean (without removing) the filter screens in the cam carriers (one filter in
each carrier). In addition, always be sure to do a thorough inspection and cleaning of the oil
pan, pick-up tube and screen as shown in the photos below before reassembly.
Cam Carrier Filter Screen
Oil Pick Up Tube/Filter Screen Assembly
REASSEMBLY
Begin by putting the new short block onto your engine stand using the same mounting points as
before.
Important Reminders:
•
Install the new one-time use PCV adapter. NOTE: Never try to reuse the original.
•
Swap over the PCV assembly and the PCV baffle plate onto the front of the block.
NOTE: No sealer is used between the baffle plate and the block.
Continued...
Bulletin Number: 02-157-14; Revised: 09/08/14

•
If equipped, swap over the lower water jacket coolant baffles into the new block.
•
Head gaskets are marked “L” and “R”. Always make sure they are properly installed while
paying close attention to the sealer application areas as outlined in the Service Manual.
•
Always make sure to clean the head bolt threads and apply engine oil to the threads and head
bolt washers before starting the torque sequence. Always follow the torque sequence closely.
•
IMPORTANT: If by chance the AVCS filter screens in the cam carriers have come loose
or fallen out during disassembly, they are directional and MUST be reinstalled in their
original position. There is an oil passage in the cam case which MUST align with a hole on
the outside diameter of the filter screen tube otherwise, oil flow to the AVCS will be restricted
or blocked resulting in engine damage.
•
Before installing the upper and lower oil pans, always thoroughly clean and inspect the
pick-up tube and screen. Always use new o-rings on the pick-up tube and both oil pans
during reassembly.
•
Once the basic “long block” has been reassembled (valve cover to valve cover), proceed with
installation of the timing components as outlined below.

IMPORTANT REMINDER: To eliminate possible confusion, it is strongly recommended
to follow the timing chain reinstallation procedure outlined in this TSB and / or the Technician
Reference Booklet (TRB) for Module 105: “Chain Driven Valve Train Boxer Engines” instead of
the Service Manual procedure.
•
To begin timing chain re-installation, turn the crankshaft COUNTER-CLOCKWISE until
the crankshaft sprocket keyway is back to the 6:00 position. This positions the pistons away
from TDC and prevents accidental contact with the valves. NOTE: The keyway is NOT a
timing mark. The oblong / oval-shaped timing mark must face front and be to the RIGHT of
the keyway as shown below. Do not confuse this mark with a mark which may be found on
the back side of the sprocket.

•
Install the chain guides and tensioner. Once proper positioning has been confirmed, pull the pin
to release the tensioner. With your hand, grab and squeeze the upper and lower chain / guides
together as shown in the reference photo below to allow the plunger in the tensioner to fully
extend and click into its furthest notch.
•
If you have 3 notches showing, you want to get one more “click” so that 4 notches are visible
as shown in the photos below. If you have 4 showing, you want to end up with 5. Whether
you start with 3 or 4 will depend on the amount of wear present on the chains and guides.
The number of clicks listed here is simply a guide. The point is to ensure proper initial chain
tension is applied to avoid creating a brief rattle sound at engine start.

If necessary, insert a plastic screwdriver handle between the lip of the block and the left side
(B2) guide. Then, VERY CAREFULLY push down on the guide just enough to get the extra
tensioner notch / “click”. When using this method, always make sure you are using plastic on
plastic and NOT metal on plastic to avoid damaging the chain guides.

Same as the left side, align the indicator links to the timing marks found on the cam sprocket
assemblies. Install the chain guides and tensioner. Once proper positioning has been
confirmed, pull the pin to release the tensioner. With your hand, grab and squeeze the upper
and lower left side chain / guides together to allow the plunger in the tensioner to extend fully
and click into its furthest notch as shown in the previous (right side) photo. If necessary,
insert a rubber-coated plier handle between the ledge area on the front of the block and the
right side (B1) lower chain guide. Then, VERY CAREFULLY lift up on the guide just
enough to get the extra “click” on the tensioner as shown in the photo below.

•
IMPORTANT: When re-installing the front cover assembly, be very careful to not allow it
to contact any of the timing sprockets. If contact does occur, it will most likely be with the
exhaust sprockets and it is almost a guarantee the silicone sealer you have put on the front
cover will be disturbed. If not properly addressed, that area will most likely be the source of
an oil leak after reassembly. Don’t hesitate to use a helper for the installation to prevent this.
•
REMINDER: When replacing the short block, in addition to transferring the crankshaft
position sensor, be sure to index the reluctor properly onto the crankshaft as shown in the
photos below. The reluctor is indexed by a dowel pin in the rear crankshaft flange which
aligns with a corresponding hole in the reluctor. It is possible to install the reluctor without
indexing it correctly. Failure to index the reluctor correctly will result in a no-start condition
due to an out of time crank position signal to the ECM.

•
Once the engine is back in the car and filled with fluids, remove the fuel pump fuse and
crank the engine over (for no more than 10 seconds at a time) to prime the oiling system until
the oil pressure warning light goes out. Re-install the fuel pump fuse then run the engine
initially with the original oil filter left on the front cover for approximately 5 minutes to catch
any other remaining debris. Check for any fluid leaks then install a new oil filter. Start the
engine again and run it for another few minutes. Shut off the engine and allow it cool down
for at least five minutes. Re-check and top off the engine oil to the full mark on the dipstick
before releasing the vehicle.
•
Be advised, some higher than expected oil consumption may occur initially following
the shortblock replacement until the new piston rings become seated. While higher than
expected normally, this oil consumption rate should not be as severe as verified prior to
the repair. This will generally improve within 1000 miles of driving until the expected oil
consumption rate is achieved.
•
Complete the following procedure (where applicable) to conclude the repair procedure, even
if no complaint of this condition has been indicated by the customer.
SERVICE PROCEDURE TO REDUCE FALSE ILLUMINATION OF LOW OIL LEVEL
WARNING LAMP (ON MODELS SO EQUIPPED)
•
Any repairs performed as part of this bulletin must include installation of the applicable
reprogramming file for this condition where applicable. (See Applicable Vehicle Model and
MY in the Warranty/ Claim Information section of this Service Bulletin.)
•
If a vehicle is presented where no repairs for actual oil consumption are required but an
oil consumption test was completed, this reprogramming must also be completed. (See
Applicable Vehicle Model and MY in the Warranty/ Claim Information section of this
Service Bulletin.)
NOTES:
SOA now highly recommends connecting the Midtronics GR8 Diagnostic Battery Charger to the
vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being
reprogrammed. Once the GR8 is connected to the vehicle, as long as the battery is fully charged, it
takes less than 3 minutes to boot-up the charger, select the Power Supply Mode, and have the battery
voltage stabilized and ready for reprogramming.
VERY IMPORTANT: This information is applicable to the Midtronics GR8 Diagnostic Battery
Charger ONLY. It does not apply to any other brand / type of “generic” battery charger whatsoever.
ONLY the GR8 and its Power Supply Mode feature has been tested and approved by Subaru of
America, Inc. (SOA).
If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8 before
proceeding to reprogram the vehicle while using the Power Supply Mode.
•
Control module failures as a result of battery discharge during reprogramming are not a
matter for warranty. Should any DTCs reset after the reprogramming update is performed,
diagnose per the procedure outlined in the applicable Service Manual.
