Crap man, I'm having a massive brain fart, I don't for the life of me remember what that second hose is for. I know it's stupid simple... But again, if you have pressure coming out of the draft tube then it's doing its job.

Ok I stayed up late doing some online research at various forums and all instances I found that had excessive blowby and wound up needing to be rebuilt all the owners also stated there trucks undercarriage was completely covered with oil maybe I'll get lucky sense mine only has a spot the size of a baseball glove. Like I said earlier borescope then injector or compression test whichever I get first I know I got my fingers crossed.
Question could the smoke I'm calling blowby be caused by diesel in my oil and only way for that to happen would be if fuel was getting past rings or if CP3 pump was leaking into crankcase correct?

Also forgot to mention before i disassembly I disabled fuel supply and let motor run out of fuel but when I removed fuel line from transfer tube to rail it was blowing out bubbles of air and fuel? Or is it cause that's just the way it is with the high rail pressure
Ran it with valve cover off and not much smoke coming out of engine but going to clean CCV hoses just because

As for the injectors and blowing bubbles, I've honestly not messed with the common rail hard parts that much. So I'd ask for @AccurateDiesel to chime in

I suspect the bubbles in the fuel line were just due to running the truck out of fuel (not a practice I would recommend). You mentioned diesel in the oil earlier - by far the most common cause is a cracked injector body leaking fuel into the under-the-valve-cover area.....
I was assuming fuel in oil or hoping that's what is causing the smoke from the draft tube. as far as running it out Of fuel I hear ya I was concerned about the few thousand psi still sitting in the rail
Had all injectors out didn't see any cracks but found one nozzle #3 injector the tip of needle was badly worn had a bad inj sitting at work so I swapped it it isn't great but looked way better
