Need help with tub drain and vent

[matchap]

Having trouble with this tub drain. Tub was switched from left to right drain. Original p trap was located 3 feet from the vertical drop in the photo without its own vent except the vent line in the photo to right of wye. The vent line to the right of the wye and ties into the vertical main stack above the toilet

The set up (unglued) in the photo creates an s trap. Should I just reconfigure to get a trap arm that is at least 3”?

Any ideas would be appreciated

NO!!!! You should just reconfigure the drain so it HAS A PROPER VENT.....

So the vent line on the right that ties into the vertical stack 5 feet from the floor is incorrect?

So the venting was done improperly when the house was built?

The vents are higher than the trap arm, not below. What you have would siphon dry and allow sewer gas into the home.

Perfect picture that shows how back siphon can happen contributing to trap seal loss
