I have been having some problems with many issues on my 05 f150. The engine was pulled and the cylinders were looked at. They determined this...
The clearance from cylinder wall to piston skirt is .003".
The build specification provided is .0015".
The shop stated the noise was heard using a stethoscope at the #2 cylinder

Is normal for a truck with 58,000 miles?

All the help is greatly appreciated since ford and my warranty company can't help me out.

Also, they can't figure out why the back of the truck is bouncing up and down at speeds around 50mph. Can anyone help me with that?

Thanks everyone.
