I just got my truck back from the dealer after they pulled the oil pan and then re-sealed and reinstalled it. I tried to check engine oil tonight and the dipstick would not come out. It will pull past the 2 O-rings and it actually comes out about 1 inch, enough to get past the plastic piece and then it is stuck. I tried twisting it which it does do in both directions and pulling / jerking it fairly hard at each position on the clock and it is definitely hung up on something. I have had it out many times before and there has never been an issue with it hanging up on something when pulling it out. This is just too bizarre. Has anyone come across such a thing before? I did a search on "stuck dipstick" and "dipstick" but nothing relevant showed up.
