Well, you made 9 more posts after the suggestion without even acknowledging it.
Rocker arms don't just get tired and break. The camshaft lobes come up and push on the valves. If the valves cannot make the full stroke, things bend and break. I say this for future readers of this thread, it sounds like you already know this.

Now that is just too touchy! Grow some skin.
We have recently had a couple of reports about exploding rockers.
I don;t know how a valve gets bent and all of the rockers get broken and there be no damage to the pistons. What else can the valves hit?
I STILL don't know what "tensioner locked up" means".
Never got clarification on the OBD code that does not exist.

Since I 'm not exactly sure of the meaning of "timing chain tensioner froze up l drove home the car ran fine" means I am guessing that you did not get a new one to install the new chain. They usually come in the chain kit and are rather difficult to reset for use after you take them out.
I am not sure what Oldblue is thinking. If the key is at 12:00 AND all 3 of the marked links line up with the "arrows" it has to be timed right.
We have had a few instances lately of broken rockers. I don't know how that happens.
So now that is given; are we at does crank doesn't start?

That code indicates the camshaft sensor is telling the ECM that a camshaft is out of time.
it’s doing it’s job , reporting a problem.
I suggest you have a close look at the timing marks. I know you are sure everything went together perfectly, but sometimes there’s a glitch.
I’ve taken the front cover and valve cover off a 2.4 towed to my place and determined the timing chain was put on backwards.

I didn't come here to upset anyone or to be treated like I'm some kind of Moron
If the tensioner would not go in or out that means it was never set. Presumably you got the hydraulic tensioner? There have been some that had to whack them like the old spring activated tensioners. If you got the spring activated kind it is wrong for your car, they should only be on non-VVT engines.
The clean one is the hydraulic.
