Jeremy......thanks for your comments and suggestions. I will give your tips a try after doing the following:
Carl52 suggested that I put a torque wrench on the harmonic balancer and give her a turn when the engine is cold, and then compare the amount of torque needed when it is hot. If the engine cranks real hard with the torque wrench when hot, then the problem is something internal. Im hoping this test shows about the same torque on the wrench on the cold and hot engines.
My other thought would be the water pump.....maybe that sucker is getting hot and causing a drag.
So, I will keep prodding and testing, and will post what I find.
Oil Pressure Gauge.....that was just a picture I had to show the gauge (engine was off). I will try to take a pic of the High Oil Pressure reading the next time I take her on a test run.
Thanks.
