Long story short, I could hear a HLA tapping, quite loudly actually. I tried a half-quart of tranny fluid for two weeks, and nothing. Drained some oil, and added a quart of Lucas, aka engine honey. Still nothing. I finally bit the bullet and dug in.
One HLA was stuck completely flat, and three others were stuck about halfway down. Lame. Change your oil, people. Good thing I have about two motors worth of HLA's laying around.
Total time was about 1.5 hours. I swear, nothing is easier to work on than a 2.2L Subaru.
