The water channel in question is on the push rod side of the engine. In
between cylinder #3 and #4 on that side of the engine is a head stud. The
channel is between this head stud and cylinder #4. The breakage is not all
the way down into the bore. At the top of the cylinder is a groove maybe 1/8
inch deep. The chip goes no deeper than the top of this groove. In fact, it
looks almost identical to the hole directly opposite the cylinder that DOES
overlap into this groove, except that hole does not appear to go anywhere.
That is why I did not notice it when I first had the head off, it looked just
like the other holes.
In a related story, I was unable to drain the water from the block using the
drain plug on the side of the engine. My Haynes manual (picture 3.6) says the
correct bolt is located to the right of the fuel pump and above the starter.
When I started this project about a week ago I got a small discharge of oil
from this hole, but no water. Is this the correct bolt to remove for draining
the block of water? If so, I may just have a bigger problem than a small chip
in a water channel. Could I have a blockage in the water system, or is this
not the correct drain point?
Hmm, Joe's block is starting to look pretty good.
