06 Caravan, like many others, plastic loop broke at top, leaving stick about an inch from the top. Others had mentioned this procedure, and I as well. Make sure engine is cooled down before attempting to remedy this. Drill hole in plastic, not much room to work with. Spray WD40 or similar product into hole where plastic is. Wait for a brief period, then put, I used a long thin wood screw, into drilled hole. A turn or two will usually do the trick. I then used a small crowbar and banked down on it, and to my chagrin the dipstick came out. Saves beadcoup bucks and complete satisfaction is at hand. Thanx to others who used this method.
