The 3.0L engine had a problem with the lifters that would cause the top end to tick. There is a TSB i believe on how to fix it. If the ticking is coming from the bottom of the engine (sometimes hard to tell) then you might have a Con-Rod knock that starting to show. Eitherway take it to a mechanic for diagnoses.

Q: Why would a 1997 Dodge Caravan engine make a tapping-ticking noise that went away after warming up but now is constant and seems to come from the top of the engine?
