Badali-Your gaskets look new around the heater flaps. Are they? If they are new, did they glue on or attach on with friction grip?---------------I remember taking a coat hanger and cleaning out my vent holes. I also flushed them with water to clean them out. They were clogged with dirt. It came out under the car onto the garage floor. I cleaned them out real good- and repaired the rubber gasket that comes out of the lower firewall. I repaired it with black silicone. They wanted something crazy like $100.00 for a new rubber grommet that comes out of the lower firewall.. I repaired it with silicone and it did just fine-------looks new again. These are the litlle things that will make a difference. If water comes into the air vent, it is supposed to have a clear way out, or it could pool in the air box and cause rust and corrosion. Luckily, my air vent box was totally clean. I put in a new filter, oiled the cable , and put the chrome and cover back on. I forgot to mention that I did put on a new flap gasket for the large rectangular flap that opens and closes over the filter. It was tricky to glue on.
