2001 sport trac
when i bought my sporttrac i purchased the extended warranty ,i purchased it use & the timing chain had a rattle in it ,,took it to the shop where i bought it ,they contacted the warranty people & suggested a new engine because they said it had 3 chains & there was a bunch of junk in my oil pan ,,,the next thing i know i'm driving a 2001 with a brand new remamnufactured 4.0 sohc ,,man i never realized how bad that other engine rrally was ...but i still have a bit of a shimmy in it when driving between 60 & 65 mph
