Jeff:
You may be on the right track. If could be a cracked block or a cracked
head. However, from my past encounters with similar problems I would
suspect it is most likely a warped head. If you remove the head, and check
the head gasket there may be tell tale signs on the gasket surface, of a
leak , from a coolant passage hole to #2 cylinder.
If there is a crack in the head or block it should be visible.
You can check the head surface for true using a straight edge and feeler
gauges. You can use a carpenters square if you do not have a straight edge
handy. Work across the head, then lengthwise and finally, diagonally. Take
feeler gauge measurements of any gap. Start by trying the gap with a 2 one
thousanths feeler gauge. If you find spaces where 2 thou slides through
then work up a thousanth at a time to see how much gap there is. If you
find any gap over 2 thou the head will need truing. A head gasket should
seal even when a head is 2 thou out.
If the head is warped, you can get it trued by a machine shop. Or just
remove the head, take it to a machine shop and have it checked for true.
I have only seen a warped block once, and it was in an MG. It was trued
without disassembly of the motor.
