Thanks to Larry Bible and Benzmac. Larry and I put the car up on ramps and pulled the valve covers and low and behold on this car with 160,000 miles, there was not even 1/2 degree stretch. I guess all those good oil changes really pay off. The marks top and bottom were as close as the eye could tell 0 - 0. Thanks again,
Brad
