[DML] Re: Delorean Choice of PRV

["welmoedj" <joe.dalton@xxxxxxxxxx>]

Hi Robert,

To approach it from another side: I am glad they decided to use the 
PRV. That's for the same reason as to why the British can't build a 
computer. They do not know how to make it leak oil! :D
My D leaves no spots or puddles of oil on the garage floor.

Welmoed.
