Ha! I like that.

did you run it and rev it a few times with the heater on once at operating temp as part of the burping process? If not give that a try.
Yep. Squeezed the tube to get out any bubbles and I've done one full track day since I swapped everything even. It's probably just my own paranoia.

If it's actually a problem, then I can say with full confidence that this old 4.6L is a beast having gone through a track day without proper cooling. I'm pretty sure the engine heard me when I said "I'm going to swap it out for an Aluminator when it goes" and is just hanging on for dear life.
