Is it a 4.0 SOHC or OHV. 98 should be a SOHC which means it may be the timing chain guides. They're plastic and break if they flop around too much. Since the chain tensioner is oil fed, for some fluke reason, it may have emptied and not put enough tension on the chain during start-up. Or the tensioner itself could be bad. Let me know if you need anything.
