I've been slowly rebuilding Red's engine after I damaged it with a broken belt and an overheat. The passenger head was destroyed so I had to find a replacement. About a year of searching ebay and I got one pretty cheap. My mechanic checked it over and gave it a green light. I installed it and completely forgot that I needed to remove this odd pipe that is in place of the temperature sensor. Of course I remember the exact second I finish the last bolt's torque. It's in a horrible place to reach, I can't seem to get any tools to grip it, and I am pretty sure I am going to have to pull the head again to get this off. I thought I'd ask here if anyone had any tips or tricks or have ever seen this on a DeLorean head before?
