Engine torque specs needed and does this engine use normal or Flex bolts?

Here are the torque specs for the engine and I have included how to use a torque wrench video in case you need it. There are two different kinds of bolts the torque to yield bolts will need to be replaced, see below:

Check out the images (below). Please let us know if you need anything else to get the problem fixed.

If the piston is broken it will need to be replaced, do you mean the skirt of the piston? Can you upload an image?

No problem, either way the engine will need to be replaced or disassembled and repaired. I like the rebuilt engine from Ford, they have a great warranty and any ford dealer will take care of the engine if you should have a problem.

Yes, you can replace one piston, but the cylinder will use oil unless you have the block re-machined and use an oversized piston.
