The intake cam lobes on bank one are ate up on my 2019 Chrysler Pacifica touring L v6. The timing chain on bank two it tight. But the chain on bank one is loose.
my question is, if I replace the cam shaft and rockers, will I be good? Or is there a problem with the chain that will just cause the same problem again? Here are the codes it has thrown.

also I made a quick video of the problem and uploaded it to my YouTube channel. Could you watch it and let me know your thoughts?
Here is the video.

hey Scotty, sorry I didn’t explain well. ...
Scotty does not usually revisit topics he has already answered. Between the "K-Seal" snake oil in the engine due to the blown head gasket and this problem you'd probably be better off looking for a used low-mileage engine from a wreck rather than digging a deeper hole with this one. Then get rid of that thing once it's running OK.
@chucktobias thanks for the reply chuck. I decided to go with the k-seal for the head gasket because I watched one of Scotty’s videos about using a head gasket sealer. I know it is a temporary solution. But honestly, I’m just trying to make the vehicle last long enough to get to next year‘s tax season where I can get something else.
Do you think that if I just replaced the one damaged intake cam shaft, that it would get me by for the next 4 months?
Unfortunately there's no way to tell from here how extensive the damage really is or what caused it in the first place. Modern engines are so complex it's going to be a real crap shoot.
The check engine light flashes and dings letting me know that disaster is imminent. So I have caught it before major disaster
I would say having torn up your camshafts alone, it already has been through a major disaster; it's barely running. The camshafts alone will be costing thousands to replace as-is, and negating that you blew the head gasket, that engine is already toast. The engine hasn't undergone catastrophic damage yet, but the flashing CEL means you shouldn't be driving it at all. You're trying to rebuild an engine, which isn't cheap in the slightest bit. Most run-of-the-mill mechanics can't rebuild a modern motor and do it properly because they're too complex. Heck, my '99 Ranger has an old 4-speed automatic transmission that I had rebuilt a few years ago by professional mechanics. It shifts much better than before, but it's not perfect in the slightest bit. Just get a "new", low mileage engine from the same year Pacifica that was wrecked, fix and sell it if possible.
Well, the engine is probably too damaged to fix. That is an interference engine and wants the chain or the cam locks up while driving. The Pistons hit the valves and the engine is pretty much destroyed
@scottykilmer hey Scotty, sorry I didn’t explain well. The engine hasn’t locked up. I don’t know if you are able to see the video I made about it. The link seems glitchy. The engine has a blown head gasket. I used a bottle of K-seal and it seems to have worked for the head gasket.
The cam stuff seems to be a separate issue. The engine still runs and I could drive it right now. The check engine light flashes and dings letting me know that disaster is imminent. So I have caught it before major disaster. I’m just not sure why the timing chain on Bank 1 is so loose compared to the chain on bank two. After inspecting all of the cams, there is only one cam with any damage. The intake cam on bank one has damaged to just about every lobe. Like I say there is zero damage to any other cam. Because there is damage to every single lobe on that one camshaft, I do not think that it is just bad rockers. I think there is a larger problem, but I am not sure exactly what is going on here?
