Subject vehicle is a 1990 E350 class C motorhome with a Ford 460 V8. Now it has been sitting in the driveway for about three days since it was last run. So I go out, wipe the stick, jamb it down the tube and immediately pull it out. Reads about 1/4-inch above the full mark. This is good as that is where I like it. But there also is a weak trail of oil up one edge of the stick for another 1/2-inch above that. Now if I wipe the stick and jamb it in the tube and count to 10 and pull it out, the oil is solidly 3/4-inch above the full mark. I have seen it with shorter counts where it will show the 1/4-inch above, then a small gap, and then some oil across the stick above the gap. I could understand if it was recently shut down that there could be oil dripping down right over the stick, confounding the reading, but as I said, this thing has been shut down for three days. Or could it be draining from the lifter valley and take longer? Could the stick be rubbing against a spot and the rubbing action causing the drip to start each time I stick it? My other vehicles don't do this.
