Also, the dancing oil cap test revealed a very bouncy cap with tons of vapor coming out, and by that i mean a stream like steam from a kettle.
whatcha thinK?
My one observation on the seals is that after using a box wrench to push them on, no easy task, i'm wondering if i may have damaged one of them?
hoping I didn't scratch a valve stem, though i'm guessing they are pretty hard.

I seriously doubt that you scratched a valve stem with anything softer than carbide.
Do a compression test and if you find low compression, do a leakage test on the weak cylinders to find out if you are having ring seal problems. That is the major cause of excessive blow by. All these engines will give some blow by. It’s the nature of a high compression engine.
I weigh 190 pounds and have a grip that could make an oyster wince. But I’m not stout enough to seat a valve seal properly with a box end wrench. I see most people use a hammer driven socket to seat them. I use a plastic factory valve seal installation tool that I bought from Baum tools over thirty years ago. It’s actually made for 9mm and 10mm Porsche valve seals but I found that it works on everything of a similar size. Remember to use the little plastic sleeves over the valve stem threads to keep from damaging the seal as you slide it into place. I drive the seal home by hitting the tool with a rubber hammer.
If you have a valve stem seal problem it will be on your exhaust valve(s). I know many diesel mechanics that don’t even bother to use intake valve seals because we don’t have vacuum like a gas rig. I use them.
I hope you used a block off plate for your discarded EGR and put a good plug in your exhaust manifold where the EGR feed pipe exits. A BB in the vacuum line works just fine if you are positive that your EGR is completely closed.
