I'm new to the site. I've been a F-150 fan/owner for the past 18 years. On my 3rd one. Currently, I have a 2002 Ford Lariat, Crew Cab, 5.3 Tri Ton. I was told recently that Ford F-150's are known for having something very serious happen to the engines when they get near 175,000-200,000 miles. Whatever this big thing is, they said can cost up to $5,000 to fix! Now, I am getting near the 200,000 mile mark and I am getting nervous. Does anyone know what this may be?
Is this true or some folk lore myth?
