Sounds to me, the rings are out of that engine plus the valve seals are junk. You have more than a PCV issue.

Is there anyway to now for sure lol.
Well that's the clincher. In a previous post you said you never noticed smoke out the tail pipes.... Throttle closed deceleration is when the engine is under the highest vacuum. You could do a dry then wet compression test to make you feel better before going into the engine but your valve stem seals and rings are shot dude.

Does anyone know why the rings or valve seal went bad at 86k miles. Is this a common thing with the magnum?
The truck started burning oil at 65k miles but I’m thinking the plenum gasket was the issue at that time and this oil eating is new.
My next best thing is to figure out if it’s worth fixing or not because The truck runs’ drives perfect and I’ve invested a lot in the custom paint and performance
Start with a compression test. If it shows bad compression, which I'm guessing it will, do a leak down test to help pin point the problem.

With all of the issues you have talked about in this thread, just pull the engine have the short block rebuilt, buy a new set of heads and reassemble. If the heads you have now are original, they are more than likely cracked and non-repairable. If you are not willing to do this, anything else is a waste of time and money.

A compression test or leak-down test will not tell you if the oil rings or the valve seals are bad.

Is it something I did to make the oil rings go bad? I did bust a lot of donuts lol I hold A record for longest donuts in east bay lol.
Is this a common issue with the 5.9?
Stupidity is the leading cause of engine failure.

Nah, I've destroyed a set of basically brand new tires in 1 continuous donuts session, no issues with my motor, not to meantion all the other donuts I used to do all the time. hell with the 4.56's it's seen over 4000 rpm for 20 minutes straight bombing down the highway. As long as you didn't run it low of oil, and be smart about it you wont hurt it.

Rev limiter? that's what valve springs are for!
Valve seals are the cheapest and easiest to do.
How do valve seals go bad? And is there any sings besides oil burning.
Keep in mind I did replace valve seals about 3/4 years ago 10k miles ago.
You could have put shitty seals in, by that I mean cheap. Heat is the biggest killer of things like valve seals. These trucks run a 195 thermostat and run above 200 generally. That means things bake.
