Knocking issues at cold start

Well, another who is in panic mode yet never returns with the final results so we can all learn.

 

You dont need to be under any apprehension about the noise, when I went to the dealer and spoke to the service people about it they said if I did not have a code I should not worry about it. Pushing 380k miles now no problem although I let it warm up a little in the morning so I don't have to hear it, this is somewhat aggravating.
I worked on a Camry that didn't throw a code but until I changed the crank ps the car would quit everywhere so.
When I bought the truck (brand new) I took it in for a noise, the mech said it was the shaft and that I should raise the volume of the radio if I did not want to hear it (these certified kids are a pita sometimes) after looking again I found the fire wall plate for the steering shaft was nowhere around.
I wish I knew what the heck the knocking sound is, I dont have a clue.
