I believe that plate doesn’t prevent gas from going DOWN, it actually prevents gas from coming back UP>
If you remove it, and look down it, you will notice there is a port a couple inches down, into the chamber that the spent cooling water is diverted on its way out the snout.
The exhaust gas come up the chamber that the plate covers, out through that bypass port, then out the snout with the spent cooling water. If that plate were removed, you would have excess build up of gas there with no where to go.
I don’t totally understand the engineering of it, but I BELIEVE, that there is a siphon type effect that goes on there. Removing that plate would make it worse. Just my 2 cents. Wait till the mechanics chime in.
