I will be working on the Tamiya 1/20 Brabham BT46. I bought this in the 80s back when I bought a 1:1 Alfa Romeo Spider and started following Formula 1.

This is the current state. I was wondering if I should re=paint the engine as a small note that I missed says to add some Gold Leaf paint to the Aluminum paint. It doesn't say how much though. So I looked for images of the Alfa Flat-12 and then wished I hadn't found them.
The actual engine block is plain Aluminum but the cylinder heads, camshaft covers, and throttle plates are gold tint, as are some other pieces. Now I am wondering if I should re-paint these or just move on.
Oh, and the distributor cap should look like a normal distributor cap rather than the spider-like thing Tamiya gives you. Again, fix or move on?
