Technical Sound of water sloshing around when turning

My new ones seemed slightly smaller than the holes, so fit easily, but do not seal completely. The engine should not produce fumes, as the breathing system should be sealed, as is the exhaust, but if any fumes are produced, it will get into the cabin. The cause should then be addressed immediately, not worry too much about the duckbills preventing the effect.

The duckbills usually perform another job, to direct water away from the bulkhead, so it drains to the ground, not soaking into sound insulation, or sitting in traps to create rust. (Or for some Puntos, not into the alternator) So leaving them out altogether could lead to problems elsewhere.
 
@ Portland Bill where did you get your new duckbills?

If it really bothers you, cut the flange off the lower side of the grommet and glue the duckbill in place with body panel acrylic sealant. That stuff is tough but it will tear away if you ever need to remove the duckbill.

After that, hose it out every time the car is washed so dirt wont build up.

When I put the fan on in the car dashboard, and rotated the vent directing knob to the position where the AIR directs to the lower part (footwell) way, I could actually sense the fume.

So yes, the duckbill must be doing the critical job = blocking the fume coming into the cabin.

I was away over the weekend, so the duckbill had not been cleaned and put back to the car. Still sitting in the garden.

But maybe it need to do it sooner or later. I thought the duckbill was hanging on something in the bonnet when I pulled it out. I couldn't tell how it will go back and get attached to the right spot in proper way.
