And did you rebuild that block yourself? Approximately how many hours on the core/block in its present state of build?

If I remember correctly you are using a normally aspirated 13B, with EC2 and RD-1 correct?

Thanks, David

Yes, I still lean toward the spark plug theory - but, the delay and the fact
that it did not appear to happen to both rotor at the same time sorts of
leaves ??? about the theory.   It does seem unlikely a few bits of plastic
would have taken out all 6 apex seals, but should be able to tell tomorrow
by peeking into the intake - if the dividers still in place then that would
pretty much eliminate that as a cause.

Well, this is the third time (charmed?) that I made the decision to divert
to an airport unintended - well unintended until it look like the best
choice given the situation {: ).

Just a bummer missing the gang at S & F

There you go again, trying the be the rotary engine glider expert.  It
is such a shame that it interrupted the trip to SnF.  I got invited to
go in a friends Lancair IV-P but am working all week.

It take a lot of confidence to go cross country after putting on a new
part of the intake system.  Even I (fly to mexico with a broken
turbo), would hesitate to do that.

I find it hard to believe that a little plastic could break [at least]
4/6 apex seals.  So the spark plug theory (of the two listed) is more
likely in my mind.

Other possibilities.. hmmm.  All seem very unlikely:  Other FOD,
detonation, loss of apex seal lubrication, lead deposits on the spark
plugs poking into the chamber, fuel contamination with grit or sand,
spark plugs actually broke and won't seal or are loose.

Glad to hear you are safe, bummer about the trip, interested to hear
the post mortum.
