Red49truck, I don't have the link but on most trucks the cowl vent handle has a spring to keep it closed tight. Does your's have one? Should it?
....and what type of material is your gasket? Had a "rubber" one that leaked because it wasn't soft enough for the vent to seal. I changed to a cork gasket and problem solved as the vent would "sink" done in it and seal it off tight....and my 37 had a spring on it to keep it tight. Not sure about your 49.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
