Grrrrrr. I'll check those preacher as that does seem highly likely. The previous owner only drove it occassionally and that was around town. He had only put it on the Interstate or Highway like 3 times. To make things worse I live 2.8 miles from work so other than that it saw no interstate driving. I did put it on the interstate to go visit family about once a month. Also, I do know that when I change the thermostat about 2 months ago it had a 180 in there. I replaced that with a 190 or 195 can't remember which one. This was based off the recommendation that an inline 6 should actually run a little warmer than a V8. So no telling how long the 180 thermostat was in there.
When I get around to overhauling it I'll check the pan again. If it has sludge build up again then I'll pay close attention to the valves and pistions and make sure they seal correctly.
