SERVICE PROCEDURE / INFORMATION
If you receive a customer concern of a tapping sound from the B2 cylinder head, confirm it is isolated
to the B2 valve train area before proceeding with any repairs. Once verified, order and replace the
intake and exhaust camshafts, the 4 intake and 4 exhaust valves, and all 8 rockers. Depending upon
the VIN (see part information table) you may also need to replace all 8 rocker pivots. To clarify, if
the VIN is BEFORE VIN D*017921 for Legacy or D*242757 for Outback, you will need to replace
the rocker pivots. Vehicles built after these VINs already incorporate the new pivots. Refer to the
service procedures outlined in the applicable Service Manual for installation.
NOTE: When setting the valve clearances, the intakes should be set to 0.13mm +0.02 / - 0.03
and the exhausts set to 0.22mm +/- 0.02. These are revised clearance specifications and are not
reflected in the Service Manual.
IMPORTANT: Do not mix old and new parts together as it will become impossible to obtain intake
valve clearances that are within specification.
TIP: An egg carton makes a perfect organizer tray. Make sure to mark it as necessary (front, intake,
exhaust) to eliminate any mixing of parts.
