Jeff,

Be very careful on selecting an oil cooler. A few years back, one builder had two in-flight oil cooler failures... not good. Maybe someone recalls the brand. Also, be sure to pressure test whatever you choose.

Someone tried using an a/c evaporator for an oil cooler and it failed within a few hours resulting in a forced landing at an air force base.

I went with a Fluidyne cooler, used by the NASCAR folks.

No experience with Earl’s version; but it appears to be the same as the Setrab (copy, made by?), which has a good reputation.
