[DeTomaso] Techno question: a fine mess--update

Dear Dr,
I'm going to jump outside the box here. Do you run a mechanical fuel pump? Then if so, do you use an OEM eccentric to operate pump lever?  Next do you use any type of aftermarket thrust bearing at front of cam shaft? Or a non OEM pin to couple cam to cam gear? Could the cam gear mounting bolt be loose? I am trying to think if any noise from things above could be transmitted to the crankshaft?

   Dear Long Distance Mechanics,


                      This morning the test drive without the AC belt is
   first.    If the noise persists, then I while the engine is warm, which
   is when the noise most commonly occurs, then the alternator belt comes
   off.

                       I failed to mention that the mechanical and garden
   hose stethoscopes both reveal essentially silent water pump, alternator
   body, AC compressor and block.


                                             Warmest regards,  Chuck
   Engles

   Charles,

   Have you systematically removed one belt at a time and run the engine,
   to narrow down the source?
