[FC] Torn Thread

[James Davis]

There are a number of ways to fix this problem.  The Corsa tech guide has 
most and the Ultra Van tech tips (available on line) show how with out 
disassembling the engine.  I usually remove the cylinder and use a one inch 
long Helicoil.  A standard 3/8 course Helicoil kit comes with 3/4 inch long 
inserts.  Clarks sells the one inch inserts to use with the kits and the 
kits also.  Be sure and run a die on the course threads of the stud before 
reinstalling it in the block and use red Locktite in the stud threads.
