Remember if you use the Conversion
Concepts type mount (with the ½” aluminum base between engine and pan)
you automatically have ½” more depth to your oil pan. Not all of it is
useable because a big part of the space is taken up by the plate – but you
still get some. And I think the plate reduces foam because the oil drips onto
the plate first and then drains into the pan (I could be wrong about this).

Tracy didn't
think the Renesis pan was deep enough. It might have been total quantity,
but I think it was more the sloshing and foam. A deeper pan would
eliminate this problem.
Tracy, if this
isn't right, please set me straight.
Thanks for the answers. Now I can start fabricating.

Just a question, Chris - why modify the Renesis oil
Pan? Do you feel you need additional oil?
Yes, from the oil pickup hole in the block. I put a
gasket on the engine side of the plate and then a tube through the plate into
the pickup hole. I made a fitting that used the two oil pickup bolt holes
and with a big drill bit make the underside of the hole through the fitting a
bit convex. I put the fitting over the tube, an "O" ring
around the tube, stick the tube through the hole in the plate and then tighten
the two bolts forcing the "O" ring against the tube and plate giving
me an air tight seal. I use a new "O" ring anytime I loosen the
fitting. I do the same for the tube end entering the sump. If you
have even a slight air leak, the pump won't producing sufficient suction to
lift the oil, so careful going is called for in fabricating this.

This is all very helpful! I'm looked at leaving the
Renesis oil pan installed. Tapping a hole in the bottom to let oil flow
to the sump. I'll mount the sump at the side of the engine, just
below the level of the oil pan. Then I'll put the pickup from the
top, turn in 90 into the side of the oil pan, using the oil level indicator
hole.
Did you run one pickup line from the bottom of the engine,
through the plate into the top of the sump, and then seal up the hole where it
went through the plate? How did you set that part up?

Rotary "hang out" is generally on Row 19 on the
flight line with cowls-off until 1330 then to the rotary engine tent for rest
of afternoon.
My "Plugs Up" installation has the oil drain to
the bottom side of the block. The oil pan area is covered with a
3/16" aluminum plate. Then the oil drains through holes (six I
believe) in the bottom of the plate and through a 2"x1"
rectangular tube (running length of plate). The rectangular tube is used
to "stand-off" the "Sump" from the plate so I
can access the pan bolts in that area (otherwise the sump would be flat up
against the plate cover the oil pan holes in that area. The oil drains
through the six holes and into the sump which is a 4x4" rectangular tube
with plates welded on both ends and various fittings and holes (such as the
fill hole and dip still hole).
I then extended the oil pickup tube through the side of the
plate and into the top of the 4x4 sump. The pickup actually goes through
a removal plate on the top of the sump, so I have access to the screen on the
bottom of the pickup tube. The tube is sealed with rubber O rings where it
goes through the plate and sump to ensure an air tight seal - you do not want
any air leaks.
The system holds 4.3 quarts of oil (you could have more by
making the sump larger - but after 325 hours, my conclusion is you don't need
more - after all this is not an aircraft engine {:>)).
Here are a couple of photos that make made this
clearer. The long blue tube is the oil filler, you can see the oil pickup
arching out of the plate and into the top of the sump.

tank
My current problem: I don't want to take up the space
below the engine with the larger 13b oil pan. I was thinking of doing
something like Ed has. I can use the renesis pan as a collector or make a
blank out of alluminum, pipe the oil to a tank sitting on the side of the
engine, then plumb it back into the pump.
Ed, how does your system get the oil to the tank? How
big is the tank? How did you connect back to the pick-up?
As always, any comments and constructive criticism are welcome.
P.S. Sorry I missed everyone at Sun and Fun. Was
there a rotary hangout that I missed?
