Re: IML: broken exhaust manifold studs

["Pete Engel" <peter.engel@xxxxxxxxxxx>]

The back stud on my 70 LeBaron was broken years ago.  About 1/4" of it stuck
out of the head.  Since I was about to install a new y-pipe I really wanted
to get rid of the phht phht phht noise that had been irritation me for
years.  I went all out to remove the broken stud.

It is truly horrible to access that back stud.  I went so far as to remove
the steering column.  After hours of leaning over that huge fender and
soaking, heating, tapping, drilling, soaking, heating, tapping, drilling  I
called that car everything but a 1970 Imperial LeBaron.

I bit the bullet and pulled the cylinder head.  When I saw the condition of
the original stamped steel head gasket I pulled the other head too.  I had
them both reconditioned and put the whole thing back together.  The engine
ran smoother than ever before.

Unless your engine has been apart recently I'd just pull the heads and get
it over with.  I suspect that you'll be happy that you did.

Subject: IML: Problem with exhaust manifold studs...

I need some expert advise with regard to the exhaust manifold studs of my
1960  Imperial.  For 10 days ago I broke the exhaust manifold flange of the
left manifold...

<snip>

The number two stud (counting from the radiator) and the last stud are
broken and almost flush with the head.
Ofcourse I can try if the 4 remaining studs and bolts will secure the
manifold but  I simply don't like the idea.

On the otherhand, I either don't like the idea of taking the head off.
And at least the last stud is very difficult (or not..) accessible with
the head in place.  So maybe I should aim for the second stud to come out.

Both studs are almost flushed with the head surface (slightly below
actually).
