August 31, 200916 yr I thought the 2.2's needed the valves adjusted....took the valve covers of my 96 2.2 legacy and see no screw adjusters.... Edited August 31, 200916 yr by bgambino typo
August 31, 200916 yr What year 2.2? Pre '97s had hydraulic lifters...post '97 2.2 had screw adjusters. Nathan
August 31, 200916 yr Author 96 (said above) well that explains it Can someone explain why subaru switched to a different lifter arrangement when the hydraulics needed NON adjustment?? Why switch to something that requires more maint?
August 31, 200916 yr Can someone explain why subaru switched to a different lifter arrangement when the hydraulics needed NON adjustment??Why switch to something that requires more maint? As part of a larger performance update to the EJ22, the hydraulic lash adjusters were dropped as they put pressure and thus performance robbing drag on the cam lobes. The solid lifters only need adjusting every 100,000 miles (thus can be done at t-belt interval) and this change along with several others netted something like a 15 HP increase with little to no loss in effeciency.
