[DeTomaso] My Engine Died at the Fun Rally This Year

[Michael Becker]

As suspected by a few listers, the cause of the damage was a valve seat.
The #8 exhaust valve seat was completely pulverized into tiny little pieces,
like those visible lodged into the top of the #8 piston.  The cause of the
valve seat dropping was a large crack in the head dead center between the
exhaust and intake seats.  It must have released enough pressure to allow
the exhaust seat to drop, but the intake seat stayed tight.  The head was
too badly hammered, so its scrap, but I have already sourced a replacement
closed chamber head and my other head is fine.

Gang,
Some of you may have heard that my engine met its end at the Fun Rally this
year.  We pulled the engine and did a post mortem on it this weekend.  Did
anybody lose any debris?  Because I think my engine may have found it!  Here
are some pictures of the gory details:
