Sorry.... wasn't quite clear in the message. Was fairly ecstatic when I
discovered the diaphragm was leaking (NOT a bad rear main)... Meaning, it
was indeed the BPV making the noise.

So, consensus so far is the 710 BPV.

As for your psychiatrist/ear doctor "shot", my reliving the sound was an
attempt at humor.

Have you been to an ear doctor or psychiatrist?  The noise should stop
when you park the car...

A replacement for what?  The rear main seal?  Or the "BPV" mentioned in
the subject line?
