I pulled my TR4 head and pulled out my spare head. Examining them I find
that both have a crack between the #2 and #3 water jacket passages. The
crack runs from one passage to the other passage and does not go anywhere
near the combustion chambers. Examining where the crack is located it
appears that there is nothing on the back side of the crack except the water
way. From everything I can see it would appear this would have no effect on
the use of head.
Now here is the question, one of the heads has this crack brazed up while
the other does not. Is this something that should be attended to before I
have a valve job done?
Again thanks for any advise.
