Since Ed is having to
remove and disassemble the engine, I would guess it’s the coolant
o-rings. It will be interesting to hear how he discovered the
leak. For the benefit of the newbies on the group, we typically monitor
coolant pressure for signs of leaks. I’ve also installed a coolant level
sensor in my purge tank that should provide an advance warning of low coolant
level.

If you guys can
humor me, what's the nature of that coolant leak? Is that the cover that tends
to gradually degrade? Is there any chance to sense that failure before it gets
significant? Like, do you experience fluid level change gradually? Pressure
change? How bout Post shut down change in pressure? Know what I mean? Time vs
pressure after shutdown?
HI
everybody - this is Laura Crook. I am sure you've all heard
that Ed Anderson had another "event" - this time in LA while visiting
family. He actually has two issues - one is the his brakes caught on
fire -not rotary related 
and the other is that he has
an internal coolant leak. So.... he has to remove and overhaul the
engine again.
Since he
is not near home he has no access to his documentation. He wrote to
me and asked me to post a notice to the list regarding the
overhaul notes that he developed and posted to his newsgroup a few
months ago. He thinks that a few people down loaded it and one may
even be in .pdf format.
He REALLY
needs somebody to email a copy of his overhaul notes to the following
