 Hi! Rusty
I keep on reading about your trials = & tribulations regarding your engine, what was the original problem?<= BR>Georges B.

Hi Georges,

In the previous configuration, I us= ed an evaporator core for an oil cooler.  This turned out to be a mi= stake, but as Ed always says, make new mistakes, not old ones.  The = best theory is that the positive displacement oil pump produces some puni= shing pressure pulses, and over time, it split the core at one of the sea= ms.  Actually, it split two of them. 

The first was damaged in shipping o= riginally, but worked fine for about 30 hours of mostly ground running. I= t then started to leak at one of the seams, and I replaced it with an und= amaged core.  That core did fine for about 10 flight hours, until I = was on my way home from the first cross country in the plane. 

The core split open at about 6000 f= eet, and nearly full throttle.  Lot's of smoke, oil, and probably so= me flames that I didn't see on the exhaust.  The result was a dead s= tick landing at a Navy helicopter training field on a Sunday.  There= wasn't any damage as a result of fire, or landing, but the engine was tr= ashed from running without oil for a handful of seconds at high throttle.=  

About $2500, and 4 months later, he= re I am, but with a real oil cooler :-)

Cheers,
Rusty (watching it rain, and hopi= ng the water doesn't rise too much again)
