Interesting note about the adjustment screw.

My problem does not appear to be a leaking or stuck open thermostat. A little on-vehicle testing indicates that the thermostat appears to be opening a little bit above 70 C. The factory service manual specifies that the 82 C thermostat does not start to open until 82C. I am pretty sure I have the 82 C thermostat. That is what the box said; but, I must admit that I probably did not check the markings on the thermostat before it went in.

Have you ever checked to confirm the opening temperature for your Wahler? If the Wahler 82C starts to open at around 70C then there is no up side to putting a new whaler in.
