It kinda sounds similar to spark knock, but with a slightly higher pitch.  I
need to drive his car to hear it again.

Doesn't matter what gear it is in.  It's all pretty much the same.  However
one thing that I left out was that on real hard accelleration the tap goes
away,  but eventually it comes back.  It's wierd......normally rod knock is
constant (noticeable at any engine speed....even idle,  worse at high RPM's)

Car runs fine......hasn't tired to overheat at all.
