You are correct.  My housing is non turbo, however the engine is assembled therefore I will not be using this port for my oil supply to my re-drive although this is a very good spot.  Thanks for all you input.

You're welcome.  BTW, what aircraft are you planning to put this in? 

Also, we're a pretty informal group, and generally on a first name basis, so consider signing your name so we'll know who we're talking to.  Not mandatory of course, particularly if you're in the witness protection program, or maybe a fugitive :-) 

Cheers,

Rusty (getting way behind on the RV-3)
