REFLECTOR: oil cooler issues

[Alex]

Hi Tom-
Without looking at a picture of your particular cooler- if it is stacked
plate type (most probably it is) the plates are not all the same inside-
some have holes to allow the oil to pass and some do not, so the flow can be
controlled by the design of the stack- the oil most certainly does flow
through the fin section, but the arrangement of having the inlet and outlet
on the same side does reduce the overall efficiency of the cooler- hard to
say by what percent, but it could be significant depending on the airflow
available and difference in temperature between the oil and the air.

Hi, I'm a new Velocity owner and had a few issues while flying it home. 
One was that there was an oil cooler leak, I've removed and will pressure
test today to determine if it's indeed the cooler or just fittings. In
looking at it I noticed that it utilizes inlet and outlet on same (side)
tank. Won't a lot of the oil just pressure right through at 75psi and not
fall through the cooling lines/fins?? Is this a normal set up or poetic
license by builder? It does run too hot (225 in cruise) and does not have a
2nd cooler. The cooler is an SW10557A which I can't seem to locate either as
far as replacement if I need one. What are most folks using?? thx much
