Another strange incident, a guy lost power on cylinder number 7. Turns out a rocker arm or rocker arm keeper on that cylinder broke. The rockers are retained in the ball/stud fashion (how cheap is that???) and to replace it the bolt holding it down is also a head bolt. With removal of it Ford considers the head/gasket compromised and the ENTIRE head must be removed so the gasket can be replaced
