What does thin oil do?
My 2005 F150, 5.4L vapor locked, cylinder 1 due to leaking injector. After replacing plugs, injectors and fuel filter, I started it and the engine knocked like hell. I drained the oil and it is super thin. Will this cause the knocking? Should I continue to pull the pan off and check for bent rod or other damage? Any suggestions or advice what to look for is greatly appreciated.

Yup this royally sucks. In my other post when this all started "2005 F-150 5.4L Locking up when cranking, Smoking & Mis-firing", 70F100longbed said it was possible to replace a bent rod without pulling the engine. but first, I have to get this stupid oil pan off....What a nightmare. After I get this off, I am sorry to be so ignorant, but what should I be looking for? Is it obvious? Can I tell right-a-way?. Seriously moping in VA. Anyone please help!

You will have to loosen the steering gear, lower the front diff if its 4x4, and remove the small crossmember under the engine to get the pan off. The fuel dilutes the oil making it thin which can damage the bearings. Its pretty tight pulling the passenger side head with the engine in the truck. You could cut open the oil filter and look for bearing material, it will look like glitter. If that's found, then the engine is done. I wouldn't put a used engine in you never know what you are getting it may have the same problem as your or bad guides, phasers, roller followers, or whatever. If you like the truck get a good reman put in. Ford's remans are backed by a 3 year unlimited mileage warranty.
