Let’s say it’s valve guides in the reman head. I could never prove this and actually get someone to warranty it!

yeah you can,... pull the exhaust manifold and inspect the stems for wetness.

You can also do a simple check by letting engine cool off all the way, pulling away the Doser pipe and hold a piece of paper a couple inches behind the turbo exhaust outlet and have someone crank the engine,.. see if the paper gets spattered with oil.
