Al,
As others have mentioned, the leak in question is probably between the water jacket & combustion chamber. Ed was suspicious while he was here in Jackson MS for our rotary seminar Memorial Day weekend because his coolant system was still pressurized after engine cool-down (without being pre-pressurized).

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 Smiley emoticon 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:
