I had a big coolant leak on my 91.  After installing a new water pump, I
found out the leak was due to a missing soft plug (?)  The plug is on the
side of the head.  I realized that the stud was broken off inside the head.
I plan on taking off the head and getting to the stud and praying that there
is no major damage elsewhere.  I think I'll need a head gasket kit and push
tube seal with the installation.  Does anyone have experience with this?
