Maintenance: Subaru Periodic Maintenance Part 4:

Valve Clearance:

Some Subaru vehicles are equipped with hydraulic valve lash adjusters, while others feature “solid” lash adjusters. Those equipped with solid adjusters require an inspection of the valve clearance at 105 months/105,000 miles. Consult the service manual to determine whether the vehicle you are servicing has solid or hydraulic valve lash adjusters. Procedures for adjusting valve clearance on solid adjuster engines can also be found there.
