1999, 3.3 V6. Had my oil pan re-sealed. When I tried to check the oil, I could not get the dipstick out. It came out a few inches, and was stuck. When I tried to start the vehicle, it made a metallic tapping noise. As it turns out, my mechanic didn't remove the dipstick before he put the oil pan back on and it bent the dipstick. He made it right, so all is well. Sharing this to hopefully save someone else from going through the same thing.
