I'm trying to get the oil dip stick tube in and it won't go in. I'm pushing it and and wiggling it and it won't go through. The tube is straight and the end is smooth and nothing blocking the hole. The motor is a 98 Explorer 5.0 and the dip stick tube is from a 94 GT. Is the dip stick tube on the Explorer motor different than the 90-95 5.0? I'm thinking it would be the same but I can't get the tube into the hole. In the pic, you can see the tube is not all the way in and I can't get it in any further. Any ideas?
