knocking sound

  1. ('03-'05) 2005 - Rod knock, piston slap, tensioner? (video)

    EJ25 - 2.5L Non-Turbo (1998-2010)
    2005 Forester x manual, swap with engine from salvage auto. Changed headgasket, timing components, seals. Really loud knock sound, I cannot tell if it’s a rod knock, piston slap, tensioner or lifters. Any ideas?
