[Fot] Spitfire oil cooler orientation

[Don Marshall]

I'm curious if anyone has their oil cooler mounted with the openings at  
the bottom and if there have been any problems.  This is for a Spitfire  
with the 1147 engine.  As best I can tell it was raced most of its life  
with the oil cooler feeding from the bottom so I'm guessing that it won't  
be a problem but I thought I'd check with the group just in case.  From  
what I've read, there may be concerns about air getting trapped at the top  
of the cooler as well as the possibility of oil not making it all the way  
through and being less effective than it should.  Does anyone have any  
direct experience with this?  Thanks, Don
