Youre crank pulley damper might have gone bad and has been moving in and out to rub on the belt cover. Doesnt look like you jumped teeth since you dont have the markers lined up right?
I had a 2.2 in my wagon that actually crank walked. this is unheard of but due to massive oil leaking from every seal imaginable I'm guessing the previous owner(s) let it get too low on oil and ruined the thrust bearings or something. I have a 2.5/2.2 in it now. good luck!
