Stop in for a cup of coffee

Good Morning Everyone. I hope all is well. Sorry about the high running temps and oil leak @Mopar Tim I agree with others that it sounds like a crankcase pressure issue if only leaks at 5K or more. I assume, you cleaned it off well, drove at rpm less than that, no leaks. Then ran it to upper rpms and this was when the leak showed?

Seriousy thinking wrong pcv, remember vac usualy drops then also so would the flow to the crankcase in Vac. Tim I have a bunch of NORS ones I can send you to try, not sure of the applications of them or how to see what the flow is on them.
