Please look @ pics ICP sensor oil leak?

Somewhere between KY and MI my truck developed a leak. Oil was everywhere under the truck. It seems to run and start just fine. It was about 1 1/2 qt low.
I pressure washed the bottom of the truck and the back of the engine, took it for a short two mile drive and snapped the pics. I can't tell for sure if it's the ICP sensor. Please take a look at these pics and tell me what you think.

Also, it looks like the heat shield may be removed already. Is that right?

In the pic with the goofy red arrow, is that the wire harness for the ICP?

In pic "Leak 2" it looks like the block is stamped 4-29-08. WTH? The truck is an '03. Maybe it's had a new engine installed???

Just remove the icp sensor and look at the plug harness and you will not be in doubt anymore. It's very common for it to leak. I think I have replaced mine twice.

Anyone have any comments on the questions below? I quoted myself:

Your exhaust heat shield is still there.
Yes, that's where it is. inside the insulated sleeve.
That could be a code. Only way to know is to have an Oasis report drawn up but even that will only show if it was done at Ford. IM fairly certain that's not the motor build date because after early 04 they moved the icp sensor to the front right of the motor.
If I were you I would check the vally to see if you have any coolant in there. Check around the when cooler hose because the are very common to leak and look like oil leaks running down the back of the motor. My best guess though would be the icp.... I'm fairly sure.

I would bet your truck got a new engine block in 08, maybe a long block

That sure is a lot of oil to come from the ICP. You could check your ICP, but I would bet you may be leaking from the HPOP cover, or turbo drain.

Definately looks like typical ICP sensor leaking... Patience is the key when changing the sensor. Make sure if the wiring is compromised to replace the pigtail.
