I don't have heat inside my canard plane. Now am considering piping
hot engine oil to the cabin through a small oil cooler with a blower.
I am looking at a Harley Dyna oil cooler - about the right size. My
question is whether such a cooler will stand the typical aircraft oil
pressure. My engine oil pressure goes up to about 80 psi when cold
then goes down to about 60 psi. I have seen Harleys with oil cooler
pressure gauges 60psi. But shouldn't they have an extra safety stress
factor?

It seems like I recall someone saying that the oil cooler did not put out
enough heat in the winter to be very useful.

It would seem like the bike cooler would be tough enough. I would use it,
but put two in line petcocks in the line to bypass the cooler, and put them
where you can reach it while you are flying. If it did leak, you could turn
it off, but as big of a consideration is the fact that you will not want to
be using it in the summer, anyway!
