When I go in the car I noticed that the heater was beginning to blow warm air. When I got to the store the temp gauges had just moved off low peg. When I got back in to go home the water gauge had moved up a bit the oil temp was still at the low peg. I decided to take it down the road a ways to check this new condition out and I found that the water and oil temp was moving up VERY slowly. Much slower then ever before. I drove about 10 miles and checked, by feel, the temp of both water manifolds and the cam covers and they seemed to be reasonable and not too hot. The water temp gauge worked its way up to 140 and the oil was about 110. On the water temp I usually run about 180.
Sorry for the long winded story but I now am convinced that I have a flakey thermostat and it is now stuck open. It may not be the whole story but I am going to change it out anyway.
More later

In normal driving it takes me about 5-8 minutes to get oil temp up to 160. --Bob
