Originally I just painted the valve cover with a high temp enamel. Looks clean. But like a few other guys, I like the exposed cam gears and thought this would be another project that would be mostly time and not a lot of money if I do it myself. I also figured if I was cutting off the front of the valve cover, I will also shave the lettering on the cover to make it as clean as possible.
I went ahead and bought a used valve cover for $65, shipped. Using a cordless reciprocating saw I trimmed off the front of the valve cover. Then I used hand files to smooth out and shape the edge.
Next up will be filing down the lettering. The "Mazda" is already gone, but the passenger side of the VC hasn't been touched yet. It's hot here in Texas.
The Intake Manifold has been by far the most time consuming but I have high hopes for it. I got a free manifold from a local guy who was going to trash it. Dirty as hell so I cleaned it up before filing.
This one I'm winging. It's pretty much the same concept as shaving the tail lenses except with metal. Just looking at the manifold in the bay there are obvious cast lines as well as surface texture:
On the right hand side of the manifold (by the Throttle body) there are two ports I capped off after deleting the Carbon canister. I decided when I shave the manifold, those ports and the metal humps at the base of the ports are going to disappear.
So when I say this is by far the most time consuming, it's just because of how complicated the surfaces of the manifold are. With the lens, it was easy to sand in one direction. On the manifold, getting an even surface finish is quite difficult. This is also still in progress, but here is some of the work.
So I hacked off the vacuum ports and just used a file to grind the area down flush with the rest of the base. That left me with a couple of small holes, which I filled with JB Weld. A sticky note is on the inside of the manifold, holding the JB weld in place till it cures. From this angle, the casting lines are not visible - which is how it would be mounted in the bay. After sanding down the JB weld flush, I'll go over the entire manifold with at least two more finer grits.
I like how the ribs now curve in like webbing. Definitely sexier.
I was thinking gold or a metallic brass for the VC/mani/intake tube and then maybe some other color for the STB and/or the exhaust manifold heat shield. If y'all have opinions for paints/color, I'm in for suggestions.
Here is how she looks today with the original painted VC and the stock manifold.
I'd love to shave or tuck the wire harness and might do bits and pieces here and there. Again - open for suggestions on additional shave projects, as well as a color theme for the bay. I'm not satisfied with what it looks like right now.
