Started with a cyl 6 misfire. Then started smoking when cold but stopping after gets to operating temp. Got a borescope in and found this first is cylinder 4, then 5, then 6. Looks to be coolant sitting in 6

What do the spark plugs look like?
If the "smoke" goes away are you sure it's not condensation?
What does the smoke smell like?
Maple syrup?
BBQ?
Forest fire?
Electrical fire?
Wet dog?
What other symptoms have you seen?

It smells sweet! Can’t say maple syrup though.
I also have had some missing coolant. And it doesn’t leak on the ground.
When it smokes there is a loss of power too.

Compression
1-180
2-180
3-180
4-170
5- about 162
6-180
Combustion gas leak test turned yellow didn’t get a pic though
So that's a positive test for gasses? I forget the colors.
My concern would be #5 based on compression readings.

Yeah positive gas test. The minimum pressure in the FSM is 124 but that’s what I thought just looks don’t match the readings
