Subject: [FlyRotary] oil return
location?
Greetings,
Attached is a picture that shows
an open port in my engine. Bruce said this would be used to return oil
from the oil cooler / filter. After finding a perfect metric to AN-12
fitting, I just found out that it won’t fit due to the mount. In
another thread, there was a picture of an engine, with all the holes labeled,
and I noticed that it didn’t even have this port. There was also no
labeled port for returning oil from the cooler. Do you just get it to
the pan any way you can? Of course now I have to find a plug for this
goofy metric hole.
On to the cowl… (someone
shoot me)

Rusty,
That hole is your oil
return hole after its been through your filter and oil cooler. Do
not fail to return oil to this hole as internally, it feeds you bearings
as well as you oil pressure controller and the oil for cooling the
rotors! Do not plug the hole- return your oil to it! If you
return your oil straight to your oil pan you will fry you bearings as well as
your rotor. Actually, you probably won't fry the rotors as the bearings will
seize first.
It appears you may able to
return your oil via the hole where your engine mounted oil fillter resided on
the block as it feeds the same galleys as the regular oil return hole.
So it appears from looking at the lubrication diagram to block off the regular
oil return provided you return it to the oil filter location if you can't
return it to that oil-return hole. I recall someone having made that
modification for some reason.
