RE: [Chrysler300] Broken Exhaust Manifold Bolt

That's the way we did it too. There is also a "hole shop" in our area
that specializes in this sort of stuff. There may be one near you if
you get really stuck.

Subject: Re: [Chrysler300] Broken Exhaust Manifold Bolt

Mark, I had the same problem with two of my 383's in the past. (the same

bolt in fact.....front right) Unless you are lucky enough to be able to
grab 
some of the bolt that may still be protruding from the head, there
really is 
only one way to remove it.

Soak the threads with penetrating oil for a few days. Generally, these
bolts 
are not actually tightened into the hole but rather they use the tension

placed on them by tightening the nut against the manifold to hold them 
securely in place so fortunately they don't (typically) require to much 
torque to unthread them.

Center punch the stud and drill out as much of the stud as possible
being 
carefull not to drill off-center or drill into the threads of the head.
Then 
use an "easy-out" to back the stud out. I'm not sure how much room you
have 
between the engine and fenderwell? The first one I did, I removed the
inner 
fender (my car's are 1965's) and the second one I was able to drill out
with 
a small 90 degree air drill. The heat from the drill bit broke the
threads 
loose and I just backed it out attached to the drill bit.

Of course the alternatives are to lift the engine or remove the head.
Good 
luck. Anyone has any better methods I'd love to know for next time.

Ryan.
