Well went to get lunch on saturday, nice day out and while waiting in the drive through noticed "im in danger"
Temps came right back down as soon as i kicked the heat on max and stayed average while the car was moving, so took it easy on the way home.
Let it all cool down then got underneath too see if something was leaking, water pump/radiator/hose/heads/etc. to find it all looked okay no build up/crust that would suggest a leak, except the rad cap looked like the heat cycling from the road trip killed it.
One radiator cap later from the lps and looks like the problem is solved. hopefully no need for more work anytime soon.
cars are stupid.
