Update. 

 

Preliminary information from Continental indicates that “the rocker arm in question is over thirty years old.  It also had numerous defects that appear to indicate that it would not pass rebuild, overhaul or serviceable limits.”

 

It also appears that the  Los Angeles FAA FSDO may be investigating.  If you have concerns about your engine or can report any  defects or deficiencies found in an engine that came from Performance  Engines, they should probably be reported there.  A Google search found the following web site for that office.

Call or write.  The life you save may be your own.
