looks like the roller quit rolling.
way back in olden times (1996), i had a bitchin' 85ish Chrysler LeBaron station wagon that had the mighty natually aspirated 2.2 in it... it started making a lifter tick noise, so i checked the oil and discovered that it was a quart low... when i took the oil cap off to add the oil, i could see 2 lobes of the cam and they both looked like someone threw a handful of sand in there... so i did what any broke guy would do: added the oil and put the cap back on. the tick went away and i drove that car for almost a year before selling it to a friend, who sold it to another friend, and on and on.. when i finally lost track of it 5 years later, that car was still running as good as it was when i had it...
