No word on the exact cause yet but did learn that Chuck was using seals from Mazdatrix.  They sell only stock Mazda seals as far as I know.

Hi Chuck,

I'm sorry to hear about your engine failure, but glad that at least it
was a soft failure.  No smoke or flames and you were making enough
power to extend your glide to an airport. :)  I will be very
interested in what you find when you tear it down.
