MTH Veranda Turbine vent retrofit kit – cap over small vent doesn't fit snugly. What to do?

Any ideas?  Do you think that it would be better to post this question on the DCS forum?

I passed on getting this engine because of the smoke outlet issue when it was released. However I am familiar with the retrofit kit, which includes a tray-type arrangement to connect the turbine exhaust to the smoke unit. I think that the earlier version of this engine had something similar although the smoke unit position was different. In theory you should be able to fill the smoke unit through the turbine exhaust as the fluid should trickle down into it. However I don't imagine that this is as efficient as being able to access the smoke unit outlet directly.

If you are concerned about losing the cap over what was the original and wrongly placed smoke exhaust, I'd put just a tiny drop of White 'n Tacky or Elmer's on the rim to hold it in place but to be able to pull it free if/when you need to access that opening.
