Heat Shields for Headers
 

After installing an LCE header on my 22re, stuff under the hood was getting HOT near the header. The Florida heat in the summer didn't help, but I wanted to cut down on the heat going into nearby parts, like the brake master cylinder, which got so hot I couldn't even grab it.

I didn't want to wrap the header, so I modified the original manifold heat shield, covering it with header wrap... Originally I was going to "glue" it on...then I used my brain and screwed it on with sheet metal screws.

The shield is installed with 4 sheet metal screws at the top, on the metal part of the factory gasket that hangs over, and then secured at the bottom with a piece of wire. You cannot see the 4 attachment screws on the top because they are under the header wrap, but they are in between the spark plug wires.

It works very well, and allows the header to breathe, but not penetrate surrounding areas with heat, as before. There are 2 strips of header wrap that I placed lengthwise along 2 tubes to keep the upper A arm bushing from roasting, and also to keep heat from rising from that area.
....

Also, this is the heat shield fabbed for the master cylinder, which attaches to the 2 left side bolts. It is 304 stainless.

nice thinking! out of curisoity though why did you not just want to wrap the header?

I've heard that it's the worst thing for headers. I think the headers can't handle the heat (unless they are ceramic?).

did you ever paint the headers? If not a nice coating of some real high temp paint will help too. I dont know if you needed to cover the MC

looks good

You should think about getting the heat shield stuff for the spark plug wires also!

If they were ceramic you wouldnt need the wrap at all!

Not sure on the quality of LCE headers but if its like the rest of the stuff they make... :laugh: is all I can do followed by :barf:!

I think the LC header has ceramic on it, but dang that thing was hot. The truck was in FL at the time though, and it was about 95 out when I first put it on. Currently I'm up north so there's less of a problem with the heat.

I decided not to do wrap because all header manufacturers void the warranty if you do that. People thought it was moisture that caused problems after wrapping (causing rust), but from what I read, the wrap actually keeps the pipes from being able to expand after heating up, especially if they are wrapped tight, and this stresses the steel tubing over and over, until it falls apart.

Ceramic headers are definitely the way to go that is for sure! I loved my downey ones alot on my 3.4!
