I could probably be the poster child of why to keep the build simple. Although whats the fun in that...
On my oil temps I worked on my baffle sealing and then did a long 2 hour+ flight with no issues. Even adjusted my damper and got the temps to adjust accordingly. So it must have been the seals.... nope.
On the next long flight, again 2 hours + about an hour and a half in the temps started rising again. I slowed down and circled the airport for about 15 mins, long enough to see the temps stabilize at 226 and long enough to get 5 hours on the engine.
Doing the 5 hour oil change I expected to see a cowl seal pushed in or a big hole or something. I found nothing. After the oil change I decided to stick my hand down the oil cooler scat tube to see if something was shoved in there. As I reached in I inadvertently was able to push the butterfly valve close. Meaning that force air was probably doing the same thing.
My fault though in the way I had the actuator arm clocked. Won't go into the details but it was an easy fix so I'm looking forward to future flights with no oil issues!
