how do I install the guiding tube for the oil dip stick?

I did not see a bracket...my engine was changed out some months ago and the dealership never did the right thing. I noticed the tube was loose I called another Toyota dealership and the never mentioned a bracket when I ordered the new one

No, i mean is the bracket still welded to the tube that you pulled out of your engine?? Not intrested in a new one for now!

I see the end where it goes into the engine block and there is a larger tube like peice on the outer side where the dipstick goes in... I don't know much about engines...I'm a female lol

My bad! Get a car person to help you out.
