Thermostatic Air Cleaners & Smog
My Air Cleaner does not have the foil duct coming from the exhaust manifold like I've seen on so many other vehicles. The port is there on the air cleaner, and the air cleaner has the flap inside the intake. The flap is hooked up to vacuum via a single port the protrudes from the top of the intake. Also, the manifold does have a heat shield on it, but there is no provision for the foil duct on it, and no duct. I'm almost inclined to believe it never had it, as the last owner claimed it passed smog this way... However, the words of a salesman, if only a salesman for a day, mean little to me.
Is this duct required to pass smog? Is there a way to accommodate the use of one without having to change the heat shield? I would hate to have to search for one at the junkyard and swap it out, would really like to get this thing smogged and in my name tomorrow!
