| SUBJECT: | PCV Valve- Design Change |
INTRODUCTION:
Subaru of America, Inc. (Subaru) is initiating a new safety recall for certain 2017-2018 model year Impreza vehicles and certain 2018 model year Crosstrek vehicles in which the Positive Crankcase Ventilation (PCV) valve may be defective.
AFFECTED VEHICLES:
| Model Year(s) | Carline | Production Date Range |
| 2017-2019 | Impreza | July 28, 2016 – March 8, 2018 |
| 2018 | Crosstrek | May 9, 2017 – April 2, 2018 |
Not all vehicles in the production range listed above are affected by this recall. Coverage must be confirmed by using the Vehicle Coverage Inquiry function on subarunet.com prior to repair.
The status of this recall will display as “Open – Remedy Not Yet Available” until sufficient parts supply is available.
REASON FOR THIS RECALL:
The PCV valve may separate and allow engine oil to enter the combustion chamber, resulting in a visible change in appearance and/or the amount of tailpipe exhaust. If driving under this condition continues, separated components from the PCV valve may enter the engine.
SAFETY RISK:
If separated components from the PCV valve enter the engine, the vehicle may experience a loss of motive power, increasing the risk of a crash.
DESCRIPTION OF THE REMEDY:
Vehicles affected by this recall will require an inspection and potential replacement of the PCV valve and hose.
OWNER NOTIFICATION:
Subaru will notify affected vehicle owners by first class mail within 60 days. Owners with a valid email address on file will also be notified by email. Retailers will be advised when the notification is scheduled.
RETAILER RESPONSIBILITY:
Please be advised that it is a violation of Federal law for a dealer to deliver a new motor vehicle covered by a recall under a sale or lease until the defect is remedied. Therefore, any Authorized Subaru Retailer failing to perform the applicable service procedures to correct all affected vehicles in their inventory prior to the vehicle being placed in service may be subject to civil penalties of up to $21,000 per violation (i.e., for each vehicle), as provided in 49 CFR §578.6 and will also be in breach of the Subaru Dealer Agreement.
Any vehicles listed in any recall/campaign that are in retailer stock must be:
- Immediately identified.
- Tagged or otherwise marked to prevent their delivery or use prior to repair.
- Repaired in accordance with the repair procedures outlined in the Product Campaign Bulletin
Retailers are to promptly follow the applicable service procedures, to correct all affected vehicles in their inventory (used, demo & SSLP). Additionally, whenever a vehicle subject to this recall is taken into retailer inventory necessary steps should be taken to ensure the recall correction has been made before selling or releasing the vehicle.
PART INFORMATION:
REMINDER: Always order the most up-to-date replacement parts based on the specific VIN being repaired.
A new parts kit, p.n. X1181AA000 consisting of a new steel PCV valve and hose is now available. The NEW-style PCV Valve is made of steel and has a BLUE ring above the hex portion as shown. The old -style is made of aluminum and has a PINK ring above the hex portion.
NOTE: P.n. SOA635322 (ThreeBond 1217H) is to be used for the PCV valve thread sealer.
SERVICE PROCEDURE / INFORMATION:
Due to a production error, the Positive Crankcase Ventilation (PCV) valve may fail causing its internal components to fall into the crankcase. As a result, the engine may smoke excessively from the exhaust. The repair involves removal of the PCV valve, inspection for failure and replacement. If the valve has failed (come apart), further action is necessary to locate and remove the failed PCV valve components.
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
The service procedures for PCV valve and hose replacement remain unchanged. Always refer to the applicable Service Manual and review the full requirements of the repair 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, necessary special tools, required processes and related one-time-use parts needed for a complete and lasting repair.
IMPORTANT: The two flow charts below provide an overview for the service procedures. The first is for Crosstrek and the second for Impreza. Detailed service procedures to be followed are also provided and must reviewed completely before proceeding.
FLOW CHART FOR CROSSTREK:
FLOW CHART FOR IMPREZA:
STEP 1: Locate the PCV valve and check the identification color. If for some reason the color cannot be identified, remove the PCV valve and confirm the condition (failed / come apart). If the (unidentifiable) PCV valve is not broken, replace it with a new (BLUE) valve and PCV hose. If the valve is broken, proceed as if it were a PINK valve using the flow chart(s) above as a guide.
- If the valve has a PINK identification ring, proceed to STEP 2.
- If the valve has a BLUE identification ring, STOP. The procedure is complete. Proceed to the Claim Reimbursement and Entry Procedures section of this bulletin.
Step 2: Remove the PINK PCV valve and inspect it for breakage. Use the photos below for reference.
- If the PCV valve is BROKEN (NG), proceed to Step 3 and remove the engine following the procedure in the applicable Service Manual.
- If the PCV valve is OK (NOT broken), replace it with the new BLUE valve and hose from the kit to complete the procedure following the applicable Service Manual.
Step 3: (If necessary), following the applicable Service Manual procedures, remove the engine to collect the PCV valve component parts that may have fallen into the engine. Remove the oil separator cover and collect the PCV valve components (4 small parts) as shown in the photos below. If all the PCV valve components cannot be collected after removing the oil separator cover, proceed with removing the engine oil pan to collect any remaining components.
TIP: If any PCV valve components remain in the oil pan-side passage, CAREFULLY apply compressed air to the oil pan-side passage as shown below.
IMPORTANT REMINDERS:
- Always wear safety glasses.
- Never reuse the oil separator cover as it is a one-time use item. Replace it with n. 11831AA260.
Step 4:
- If all the broken PCV valve components cannot be found and collected, replace the short block assembly along with a new PCV valve and hose (kit) following the applicable Service Manual procedures.
- If all the broken PCV valve components are found and collected, install a new separator cover, PCV valve and hose (kit) then reassemble the vehicle following the applicable Service Manual procedures to complete the procedure.
