That is certainly how I see it from the pictures....the top of the T should always be higher than the bottom of the main evaporator pan, and have a cap with a small hole (about 1/4 inch) hole in it....you can use a threaded piece it you still want to have access close to the drain line. Only costs a few bucks in PVC fittings and pipe...

Do you have more when the unit cycles off?
I have seen many times where there is a sag in the lineafter the trap. In other words the line has 2 traps. If this is the case the water will move up and down in the trap, at times raising the level up in to the connection at the coil. The air between the traps is the culprit.
If this is the case,try adding some height to the T you have installed after the trap and drill a hole in the cap.
