brycarp Posted February 27, 2012 Share Posted February 27, 2012 I'm wondering whether someone can tell me what the deal is with valve adjustment for an EJ18 motor in a 1995 Impreza L. I've never had the valve covers off this motor, but when I did for my 1996 Impreza Outback EJ22, there were no screw adjusters and I think that's either adjusted with shims or has hydraulic lifters. Sorry to be so clueless - it's been a while since I paid attention, but the lifters are a bit noisy on the '95 EJ18, so I'll probably pop the covers soon. Thanks, Bry Quote Link to comment Share on other sites More sharing options...
danbennett2u Posted February 27, 2012 Share Posted February 27, 2012 They are hydraulic, no adjustment necessary Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 27, 2012 Share Posted February 27, 2012 Noisy HLAs can sometimes be cured by half a bottle of Marvels Mystery Oil poured in the crankcase and run for a few hundred miles. Change with fresh oil and filter. To help keep the lifter ticks away I run Valvoline Maxlife 5w30. It cleans everything in the crankcase and helps condition seals. Seafoam works as well, with similar results. Quote Link to comment Share on other sites More sharing options...
