Wow that’s a tough call. Since you are doing head studs anyway I would take a chance on it and flush now. IMHO. You might ADD a turbo cleaning to your list. I am sure by now the unison ring is getting pretty rusted. Good Luck. WELCOME TO THE .ORG !!

The CCV mod is were you plug off the crank case vent that dumps oil vapor from the valve cover to the turbo inlet. Then I turned the elbow that is on the valve cover 90 deg and attached 8 feet of 1 inch clear tubing to it. I tied the tubing to the frame along the driver side to keep the oil vapor smell out of the cab. The reason for doing this mod it that all that oil vapor over time will collect inside and foul your inter-cooler. This oil will also lead to the failure rubber boots that connects the turbo pipes to everything else. Good luck with your truck you seam to be off to a good start. Just so you know typing in all caps is considered YELLING on most forums along with being hard to read.

if possible don't run the engine when it is ingesting coolant. not only you run the risk of hydrolock and possibly base engine damage but all that moisture in the combustion chamber is NOT good for your fuel injectors....... running the engine will give you small amounts of coolant in the oil.

water/coolant is not a lubricant. it doesn't belong anywhere near oil

Yes, for sure plan on an oil change. This is a hard judgement call. If it was my truck I would chance it if it wasn't burning a ton of water. If it was someone elses truck I was working one, NO WAY!!
