Looking at your exhaust manifold, it looks like an oil leak from your valve cover.

Sounds like you need new valve cover gaskets. Not a big deal changing them.

Most likely the oil has built up on the metal shield you mention. The hotter the exhaust gets the more smoke you will see until there is either fire or the oil burns off.

Fires on your year isn't common, but it is possible if enough oil is present.

Keeps the heat off the fans. I've been running headers for a few years with no shield and no problems.

I see smoke, but dunno what you were talking about because you posted in a seperate post. Please link us up. Could be a cracked manifold or a leaky valve cover from the looks.
