Wife's Fit (2009 base MT, 80k miles) is making more and more noise at idle. Car runs fine and gets 38mpg. I don't drive it much so just recently noticed it making more noise than usual when she pulled into the driveway while I was standing there. Has already had the lost motion spring (LMS) recall. Video below will let you hear the sound. It sounds like maybe just noisy injectors, but suppose it could be valves getting loose, or even the LMS failing? I'm not very experienced with Honda engines so can't make this diagnosis myself - hence seeking opinions from you guys. I am planning on doing valve lash adjustment in the very near future.
