Well the engine was up to temperature when I tried extracting the oil but perhaps not really hot, hot, hot. Does the dip stick reach the true bottom of the oil pan? I'm thinking not but rather that it reaches a point that can measure the low point on the dip stick. The extractor tub will go about 2" further in than the dip stick before it "thumps" on the bottom or something. So, am I at the true bottom of the pan or is there an obstacle such as the oil pump or other object directly below the dip stick tub that I might be hitting? If so is there any way of getting past such an object?
