Using a leak down tester (or air pressure in cylinder) you should be able to hear air escaping into the exhaust or intake if you have a leaking valve.
Blackstone labs say no coolant found in oil

This has been a learning curve for sure , I followed the instructions that were in the test kit , plus watched several YouTube videos . I’ll do the co2 tomorrow and post what I find . Fingers crossed .
i would call it 165. it is important to crank for about the same amount of time on each cyl. looking good so far.

Ok , I’ve fooled around with this combustion leak test seems all day , the picture of the milk jug is how much antifreeze I took out with a turkey baster , it was going fine both times ! But !!! Well you see , yes I cleaned the test tube and bubble well tried again , stayed blue ! But then the antifreeze comes up ? Did I take out enough antifreeze? Or do I have bigger problems?
you just sucked up antifreeze. looks good
you have to remove quite a bit of coolant to avoid sucking it up. Some kits have dual chambers to deal with this as well. Remove a bit more and try again with fresh dye. For a proper reading, you dont want any antifreeze mixed in with it.

I held onto the test kit, just a rental from autozone
That’s my next step
You're in Nashville, right?
@Zjohnsonua and @RocketCityCrzrs are fantastic cruiser heads down in Huntsville - best of the best. They're quite affordable. They did my top end rebuild a while ago. I'd just ship it down there and be done.

Thanks for the information I truly appreciate that , I can’t find anyone in town to dive that deep on it . That’s definitely beyond my pay grade

+1 on Cory and rocket city cruisers.
I’ve had similar head gasket trouble shooting and Ive confirmed this morning. When I’ve done a cold/hot compression test, nothing stood out. However, a borescope on a cold engine confirmed coolant in cyl 6.
Since you’ve done the compression test, you should be more than capable to shove a camera in there, amazon has them for 25$, they hook up to your phone.

Would a small digital scope camera work ?
Try it and tell us
Shouldnt matter as long as it has light on it and you can shove it down the hole

If your'e burning that much coolant, you're looking for a clean piston top. That coolant is steam cleaning it.
I've got a little Aliexpress-level scope that honestly works great. It's not actually that surprising when you think how small, cheap and good the camera is in your average smartphone at this point. They're just putting a similar camera module on the end of a little flexi-arm. I use it maybe once a year, but man is it nice that single time, and for the price I'd buy another if it broke.
