I recieved a private response with a picture of the "add on" pump shaft 
extension (with separate oil intake) and a contact email for the maker. 
I've already made email contact with the maker of that device, PCV 
Technologies..
 
I never did get a batch mail copy of the thread, and I dont know how 
easy/difficult/involved that is going to be. I am actively tearing down 
a 13B core at the present time. It's actually one of THREE I snagged off 
Ebay last week for a pretty decent price (if they all end up 
working/being workable). I just went back out and looked at the cores, 
and NONE of them have the actual oil injector pump attached to them.
 
Is there any reason that I wouldnt be able to put an older mechanically 
controlled pump on a newer gen engine (provided the device from PCV is 
in the assembly to serve as the metering pumps mounting surface and oil 
intake source?
 
I am definitely looking forward to picking some of the brains on this 
group/listserv.... so much more QUALITY of information than 
rec.aviation.homebuilt... nice guys over there.. but the technical level 
of information here is outstanding... whats funny is, even though I 
never had a science major degree, I took a lot of science major 
courses.. the numbers/math in some of the other threads is bringing back 
memories (not all of em pleasant, either) but at least I'm keeping up.
 
Thanks and looking forward to feedback.
