I have had my '97 Expedition {4.6L} since new, and She just now turned a cool 178K~~
Only problem I have ever had was the serpentine belt blew and tangled up around the pulley. Worst part was, I was at the entrance to one of the tunnels in N.Y. (Without my tools in the back) In rush hour, tryin' to get my Daughter to the docks to get on a cruise with Her boyfriend. Hailed a Taxi, got them off and then had to call AAA and get a flatbed to take me 100 mls. back to Philly.~~~WTF.? Had to remove tools to make room for luggage. Go Figure.!!
Only time She let me down..... Not to mention it was atleast 98* out that day.
