[VintageLambo] Espada air leaks (more)

I"m on a roll, I might as well keep sharing. Ya know how we are always complaining about the lousy air leaks, poor smell and noise of the Espada? Well I think I"ve found the major culprit! Belive it or not, those darling air intakes we"re so proud of on the hood leak like a sieve. I thought I found of them all with a flashlight on the firewall, but the air path is so long from the duct, light can"t be seen down it. There are three general problems with them. First, the control cable slider that opens/closes them isn"t adjusted to close completely. I fixed this and it made a difference, but I could still force air down there. So, Second I took off the inlet duct housing where the flap vane is, and lo and behold, the flap vane wasn"t sealing against anything. Eons ago, the brainiacs who built the car used an open cell low density foam seal around the flap vane closing surface. There were about 6-7 forlorn cells dangling from a piece of metal in there leftover from the Hoover administration. Major air leaks around the flap vane. I used some closed cell foam like you would use on a door seal that was cut to fit. Attached with silicone, and sealed both top and bottom of the flap vane mating surface. Lastly, when I took off the duct inlet, the bottom mounting surface to the fender was leaking too! So I had air and noise leaks from the vane being open, the foam missing, and hot air from the gap between the fender and duct bottom plate all entering the cabin. When I reattached it to the fender, I used a liberal amount of silicone to seal it to the fender. This is happening in your car too! Before final assembly, I bead blasted and painted my duct housing and the NACA inlet too. I plan on putting some kind of seal around the front of the duct to channel only cool air from the outside into the inner duct housing and into the car. One other fix I will be implementing is to close off the roof vent. I don"t smoke or eat in the car, so the only odors are generated by me (insert joke here). If I need to discharge air, I can open the quarter window behind my seat, now that I have repaired the handle and replaced the window seal back there. Back to leather dying tomorrow. I hope to finish with that this weekend, but I may go skiing instead, shoosh, woosh... Doc
