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 email address:
