Fixing my exhaust leaks, got a new pipe to replace the one that rattles…
Also i hose clamped the cat heat shields.And upon removing the farthest right fastener I found it to be not even tight… and its broken below the surface of the head:
And here you can see I have already removed and replaced the two broken studs:
And here is the exhaust manifold removed (I also removed and re-tapped the bolt i snapped while removing heatshield):
Main questions:
How much should it cost to plane the exhaust manifold? As it is quite badly warped.
How would I clean/prep the head for gasket mating? Currently its coated in soot/carbon where the exhaust leak was.
Can I re-use the head-to-manifold gasket? And can i also re-use the manifold-to-downpipe gasket?
Anything else I can try to remove the stuck bolt? I already tried (in order) : drilling, easy out (broke inside ofc), more drilling, punch technique.
If I can’t get it out, how much would a shop charge to remove it?Other than that really annoying bolt, everything else is going well…

Yeah I have seen that multiple times, thanks however. The punch method (which was the only method that might have worked) wasn’t working since I can’t orient the punch to spin the bolt. Its too constricted. I broke an easy-out in the bolt, so i can’t drill it out again and try another.
I tried again this morning, and upon just making it worse, I am just going to take it to the shops instead.Just to re-iterate:
“How would I clean/prep the head for gasket mating?

And can i also re-use the manifold-to-downpipe gasket?”If it is too much to get the bolt removed, I will have to leave it as it is, and just get the exhaust manifold flattened.

Heres how I would prep the head and block. you can buy a smaller sanding block.
if the gaskets are metal reuse if not I would replace.

They are steel, but they have carbon build up on them (in between the steel sheets). Would I have to somehow clean off the areas between the steel sheets?
Sorry when I asked about the head, I didn’t mean head gasket surface, I mean’t head to exhaust manifold area.

Thanks! BTW I was able to pinpoint my rattle to a tee, the gasket that went from the cat to the mid-pipe (small one) had disintegrated, and every time the pipe flexed, the metal portion of the pipe would hit the cat flange, and rattle like crazy. Probably why the service bulletin Honda put out was to replace those gaskets / spring bolts.
