I just bought a used 2007 tacoma 4x4 access cab 2.7l. I went to check the oil today and there appears to be a piece of the plastic end of the dipstick handle stuck in the tube down about 1" down from the top. there is a visible slot where you can still pass the dipstick through but I am unable to get an accurate reading on the dipstick as it smears as it comes through. and requires a significant amount of force to insert/ pull. There should not be anything 1" down from the top of the tube correct? I have tried to pull it out with a cutoff allen key but didn't want to pull to hard in case it is meant to be there! Has anyone replaced the entire tube?
