A good friend of mine bought a 1997 F150 2wd, regular cab, long bed 4.2L 5spd new in the spring of '97. The truck now has 72,143 miles as it sits, with a broken(not thrown) connecting rod. This truck was routinely maintained, and babied for all of its life. There's not much that can prevent a rod from breaking, other than being easy on an engine, and this one I don't think ever saw 4500 rpms. This worries me, my '01 4.2L has 94,000 miles on it and they haven't been "easy miles". Is this a common problem in these engines or was my buddy just the "unlucky" one?
Thanks

I don't think there's a single thread posted on this site regarding broken rods. I think he was simply unlucky. It's certainly not a common problem, in any vehicle for that matter. I know plenty of guys who race their 4.2's and run nitrous through them and have in excess of 100k miles. Other than the fixed gasket failure problem on the 97 and 98's, the motors are pretty tough.
which is probably why no one responded to this thread, because there's simply nothing to discuss.
Yeah, your friend probably had a leaky intake gasket that didn't get fixed, thus the rod. Water+oil....bad combination. This was a problem in the 97-98 trucks. 99 and up are ok. Your 01 will be fine.
Your truck will last longer if you have a hot looking chick sitting in the passenger seat with short shorts on and one foot up on the dashboard. I find that this set up helps maximize the life of your trucks motor, as well as make passing motorists happy
