franey Posted September 10, 2004 Report Share Posted September 10, 2004 I am sure at one time or another this question has been asked , but i do not remember the answer. Was the north star engine block ever modified to prevent the head bolts from pulling the threads outl. I have owned several cars with aluminum blocks and never heard of or experienced this problem with any of them. Now i know some one is going to bring up the reason for the problem is improper collant maint. , but WE all have read too many times that someone on this board owned their car from day one , took all the care needed to prevent the problem and still wound up with a head bolt pulling the threads out. Mileage also does not seem to be the underlying problem , since we have seen engines with problem in the low 30000, mile range all the way up to over 180,000 miles. If anyone knows wheither their ev er was a mod. , what year would it have been done. Link to comment Share on other sites More sharing options...
