Who has change the dipstick tube? I snapped the plastic handle off of my dipstick and went to remove the dipstick tube to change the dipstick but I cant get the SOB out!! I have removed the nut from the EGR cooler and the bolt on the oil pan that holds it into place but she wont budge. I even tried visegrips on the tube and beating it out with a hmmer but still nothing!! I havent gotten the new tube I ordered yet so i cant see how its inserted, does it have a flonge that is recessed int the pan/block??
