[QUOTE="sb69mustang, post: 1054809, member: 78848"] I have a 2007 with the 4.0 v6. mine has 174000. I have owned it 7 years. It has always gotten 12 to 18 mpg. I recently replace my motor when it developed the 4.0 death rattle. Lots of videos on YouTube about the death rattle. These have 2 timing chains one on front one on back. Have to pull motor to fix issues with the parts that tension the timing chains. Once it starts if you don't fix promptly the cam shaft bearings can have issues. I chose to replace the motor because my mechanic wouldn't guarantee it. Contacted the local Ford dealership, it takes special tools, and they told me of the camshaft issues. I chose to get a rebuilt motor, final cost $9340. I love my truck, hate the gas mileage. But to get another truck it would have cost just as much and no guarantee it wouldn't have the same issue. I'm hoping for another 170000 miles. [/QUOTE]
