Timing chain is shot and/or the little gizmo that
takes up the slack [tensioner? whatever]. Don't rev it
up too high until you get a new timing set. Some
engines get really, really sick if the chain *jumps a
tooth*. It could last for hours, days, weeks, months,
years, or centuries. My 195K mile doggy Dodge 318 has
been jumpy for 5 years. If I cherished it, I wouldn't
drive it until I got it fixed. I just center the range
on the right timing mark. Plugs look better than
wifey's *new* car's plugs. Nice and tan. I have too
many cars, and too little time and money.
