I changed oil today and put in one qt. of Rislone. Let the truck run for about 10-15 minutes. Temp got to about 182, no oil leaks except for maybe just a very thin line trace where the head mounts to the block. At slow idle, the truck is posting oil pressure of a hair above 30, after applying rpm's, goes to 60. Truck runs and idles perfect. Maybe I just have a good oil pressure. Still will have the gauge checked when I can locate a manual pressure gauge. Pump is working because I pulled valve cover and oiler is pumping oil into the rocker arm tubes. Not as much toward the front but it is getting oil and probably will get more when going down the road. By the way, thanks to all who have replied. I apprciate it.
