MC oil pressure update: What the Gods want...

[R Mangas]

   Since you're going to be pulling the motor anyway, if it was me I'd find
a way to drive the oil pump electrically and run it with the head on, then
off.  I don't know exactly what I'd be expecting, but something is sure Not
Right!

>else {

>	-hone if necessary
>	-install all your new parts
>	-re-install it and sacrifice old block to Audi gods

>either way, sounds like the Audi gods want a sacrifice :-/
