2008 Mercury Mountaineer, V6.
Last mechanic to change the oil must have used an impact wrench to tighten the drain plug. Can't budge it even with a 28" break bar.
Trying to siphon the oil out with a Harbor Freight hand siphon pump, but the dipstick hose meets an obstruction about 3/4 the length of the dipstick, doesn't reach the crankcase--maybe a guide for the dipstick?
Any ideas, clues, or suggestions about how to proceed?
