A broken rocker arm stud may be encountered on a 1985 2.5L engine. This condition may be the result of a shallow stud hole in the cylinder head.
Remove broken stud before installing new stud. Grinding a small amount off the end of the new stud prior to installing it in the head will usually correct
this condition.
