Another update. I started the car with the radiator cap off. I used the infrared thermometer, pointing it at the thermostat cover periodically. After a half hour, the highest temp showing up on the gauge was 160. The corresponding temp showing on my infrared thermometer was about 155. At start up, the oil pressure was 55. After one half hour at idle, the oil pressure dropped to 30. Because it didn't get hot enough to open the thermostat, I don't know if the cooling system is moving coolant or not. Of course some of the checks suggested were not possible either. I am nervous about the lack of oil pressure, and especially the loss of power I experienced the first time. There are some 50 mph back roads I could test it out on to see if I can get it to heat up and lose oil pressure again. Besides all the checks, the only thing I really did different was to change the 100% coolant to a 50:50 ratio. At what temp and oil pressure do I need to pull the car over and shut it off?
A local British shop near me charges $65 to go through a 5 page checklist. Unless someone has any other things I can do, I think I am just ready to take it in there and see what they have to say. What do you think?
