Well, on a ministry trip, I noticed a hot, oily smell when we idled at a red light. On down the road, I began to see little fingers of oil creeping along the top of my hood. Upon closer inspection, there was oil everywhere in the engine compartment. The problem turned out to be the dipstick. Over the years, the gasket at the top of the stick shrunk.
Engine oil is always under pressure.
This happened once before and was cured by the application of a simple piece of duct tape. In the Bible, oil represents the Holy Spirit. He provides a hedge against undue friction and keeps us running smoothly. People, like Tonka, need to have plenty of oil. The oil needs to be confined to the proper area.
