Default Exhaust manifold to head bolt thread

Hi, could anyone be kind enough to tell me what the thread of the Exhaust manifold to head bolt is?
One of mine has fallen out, this might have something to do with my idle misfire

Is it a 6 or 8 ?? I don't think it would be causing an idle misfire i'd be more looking for an air intake leak

I would suggest replacing them with some high tensile ones. Exhaust bolts over time get brittle and snap thus making life really lame to get out. I would also suggest using female hex bolts to make them easier to get to.
Up to you but my current exhaust bolts have been in 3 cars and in and oh many many many times.

If you're just after one manifold bolt, your local dealer may be able to get it for you. Bayford Spares quoted me $6 each.

Which is the one that fell out, and how???

Front bottom bolt, I dunno how it fell it. I went to check their tension, one was gone....
They aren't standard as I have a set of extractors

Default Re: Exhaust manifold to head bolt thread

if they are the same as ef el bolts, im pretty sure they are M10 x 1.5 pitch?
take another bolt out and go into bunnings. bolt section
they have a sizing rack of bolts and nuts
screw it in and match up the thread
they may even keep a bolt in stock that fits
