Ed, since a number of people have asked about my project, I'll give you

the

current status. After my 2 incidents caused by the same type oil cooler

which I

am embarassed to admit that I used very poor judgement, I got a lot of

"advice"

from my brother (also an engr and pilot). This caused my wife to really

give me

a hard time over the rotary engine to the point that I decided to have a

cooling

off period, plus I had worked solidly thru the previous 4 summers on the

plane.

I believe that things have settled down enough that I can now resume

work on the

plane. Since I was due for an annual, I have removed the engine/psru,

and will

inspect it to ensure that it is a-ok. Also, the Mazda oil cooler is

going into

the wing (out of the engine compartment) which is more easily

accomplished with

the engine out of the plane. I expect it to have it back in the air 1st

qtr of

next year.

Thx for asking and good luck with your project.

regards, Chuck H

Understandably, wives might tend to view a "certified" aircraft engine with
less angst than an "experimental" rotary meant for a car.  Getting the oil
cooler out of the engine compartment is certainly understandable given your
experience. I was fortunate when I had my oil lead (from the PSRU) unit.  It
flew back on the exhaust and cooked to a mess, but apparently my thick
walled headers with air blowing on them from the oil cooler just was not hot
enough to ignite the oil.  I wonder if there is any difference in mineral
based oil and synthetic oil as far as flash point.  I believe I recalled you
used Royal Purple.

Well, good luck with the rebuild/annual and hope you are back in the air
soon.

Best Regards

Ed.
