LBZ Fuel Knock

[Janimal444]

I have a question on fuel knock for you guys. I had thought the knocking I was hearing from my truck was definitely fuel knock. It has gotten progressively worse. However, now when I shut the truck off, during the shutdown there is a very distinct knock/rattle. I guess my question is would a problem with injector cause a knocking/rattling sound like this upon shutdown of the truck? I would think not.

I cant imagine how it could.

Well this noise has gotten progressively worse. Take a look at the video I took, I wasn't sure how to upload here so I posted it to youtube. You can here a slight knock/rattle at idle than a horrible noise at shutdown. Does this every time now and there appears to be no noise when giving the motor any throttle at all, only at idle. Any thoughts on what I am dealing with here?

I'm starting to think maybe it is a loose torque converter, although it sounded like the noise was internal to the engine.

Flexplate?

Not sure what the sound is but that sounds horrible. Might check out the flexplate
