hey, i noticed theres two different part numbers for the exhaust manifold gaskets, one for the cylinder head side and one for the exhaust side. Looking at my old gasket it appears that the only difference is that little tab on the bottom. Do i really need to get the two different ones? my dealership only has the exhaust side in stock, could i just use two of those?

The exhaust manifold gasket is a 2-piece design, but it shouldn't have two part numbers.

Oddly, it seems that he's right, at least for the US Spec 1.6. The Mazda parts book shows the two pieces as separate items, part numbers B695-13-460A and B695-13-462, and on the diagram they're not conjoined by the line that typically denotes multiple parts as a package. See attachment.

To answer the original question, assuming your exhaust gasket is damaged and in need of replacing, try it and see. I think that the manifold side is the one with the bead rolled in it and the head side the flat piece, so you might be able to re-use that side. If your old gasket isn't destroyed however, re-use it. That's what most folks do (myself included), and I believe that FM, Greddy, etc actually recommend it.

I believe that the gasket is made up of two pieces spot welded together. They probably call out both parts more for internal engineering and procurement reasons and it got that way into the workshop manual.

You're probably right. I seem to recall that mine were sort of sticking together at one end, I guess that in reality they had actually come un-welded at the other end instead. But all told I've had the manifold off and on three times over the past month, and it's still working fine.

PenPen, have we sufficiently obfuscated this topic?

I am about to add a begi cast manifold to an 04 engine. I should reuse the exhaust manifold gasket?
If I need new what kind should i look for.
