Re: coolant leak
Take a look at the
picture of the month on Tracy's web site. That is a picture of
the coolant spouting from Ed's engine when it was dead cold. When he
lifted the pressure relief lever on the coolant cap, it pressurized the
overflow tank. He knew then that there might be a problem. His
First thought was that the diameter of the O ring's that came in the overhaul
kit might have been a little small. I guess we will hear exactly
what the problem was when he gets the engine
open.
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:
