After bead blasting the aluminum intake manifold, I applied a very thin coat of high temp silver paint. The paint will prevent the raw aluminum from oxidizing.
The flange thicknesses of the intake manifold and exhaust manifold vary by 3/16 of an inch. To compensate for the difference, I attached a shim to the thinner flange. Now the washer and nut apply the proper pressure to each flange preventing leaks. Why can't these manufacturers engineer these parts to fit. It isn't "rocket surgery". But, it is what it is.
Now, I am in the process of rebuilding the side-draft Weber carburetor. As I explained in a previous post, the carburetor was clogged with dirt and varnish. Cleaning is the first step in the rebuilding process. This may take some time.
Stay tuned,
Tom McCurry
