2001 dodge ram 2500 24 valve cummins knocking

2001 ram 2500 turbodiesel knocking recently. Seems to be coming from the torque converter/flexplate area, has good oil pressure. Broken/cracked flexplate maybe? Sounds kinda like a rod knock, but just started making this recently, maintenance has been done regularly. 190k miles. Any input??

2006 5.9L cummins turbo diesel (Knocking)
This is a 2006 5.9L cummins mega cab, has 143000 miles on it and has a knocking sound to it. What does everyone think it is. It has no blow by so I can't imagine it's a piston. Adjusted the valves, still ticking, Only other 2 things it could be would be injector knocking, and/or CP3 pump ticking??? Any thoughts would be great thanks. Oh, by they way I've run alot of injector cleaner through it already...

trying to determine if the flexplate is bent / warped on the 455. Attached is a video of the start-up and idle of the flexplate disconnected from the torque converter.

01 Cummins: Adjusting Valve Lash
Music: Heath Morris - Going Away *I have his permission to use his music in my videos* http://HeathMorrisMusic.com Adjusting the valve lash on the 24v cummins is super easy! only took me a half an hour. you want to take your time, and make sure all the valves are set up the same. tools needed: 1/2" ratchet or breaker bar 22mm or 15/16" socket for alternator 14mm box wrench 5mm allen wrench or similar 3/8" ratchet 10mm .010 and .020 feeler gauges Thanks for Watching!
