Charlie,
Here's what I have for coolant flow. Water neck (that's what I call it)
needs a plug to replace the thermoset. NPT tap and plug but don't
remember the size. Drill a small hole (#30) in the thermostat plug to
allow a path for air to migrate to the upper half of the water neck.
Water out of engine\ top half of water neck, I have the radiator feed
hose, water temperature sensor, -4 hose to a high spot on the swirl tank
above the normal water level. I also have a Schrader valve for initial
air purge, WP pressure sensor testing and radiator cap testing. I had
1/8 NPT fitting welded high on the top of the water neck for the -4
fitting and Schrader valve. The temperature sensor also required a
fitting. There is a port for the factory water temperature sensor. My
engine came with the sensor but I'm using it as a plug. I think others
have calibrated the EM2/3 to use the stock sensor.
For the lower half of the water neck\ water return to engine I have the
radiator hose and a -10 hose from bottom of the swirl tank. The -10 is
oversized but aids in filling up the system since I don't have a cap on
the radiators.
My heater outlet port on the rear iron is plugged. Bruce T recommends
not removing the factory press in fitting due to possible housing
damage.
Oil out on the front iron and returned at the filter mount pad. The
outlet is 18MM thread if I remember correctly. I use Dale's adapter
block for the oil return and a remote oil filter adapter. I use -10 oil
hose but others use -8. The adapter block has ports for the gearbox
feed, oil temperature and oil pressure sensors. Some remote oil filter
adapters provide two inlet and outlet ports. This offers another
convenient place to added sensors. There is an oil sensor port in the
housing below the filter pad. I don't remember the thread size but I
recall it was different from the other engine fittings. Possible 1/8"
British threads?
One of the oil paths below the filter pad may go directly to the
pressure regulator but not sure.

Subject: [FlyRotary] Renesis plumbing diagrams?
I've got my intake manifold & heat exchangers mounted, & need to start
'plumbing' work. I thought I had saved flow path diagrams for the
Renesis, but I can't seem to find them now. Anyone have oil & water
diagrams they can share?
The only info I've been able to find so far indicates that cooling water
exits the block via the top water pump port & returns in the lower port,
& the heater send port is the one next to the flywheel on the spark plug
side. The small port at the top of the flywheel-end iron seems to have a
matching port on the return side of the water pump fittings; is that an
acceptable place to tie this line, or should it go straight to the swirl
pot?
Any options other than a big pipe tap to plug the inlet/outlet passage
used by the thermostat?
For oil, the Renesis images I've been able to find show an oil filter
mount low on the accessory cover; not what I've got, and an oil port low
in the flywheel-end iron, also not what I've got. Assuming that oil
leaves the pump at the accessory case oil port, flows through the
cooler, and then to the filter mount 'tower' that bolts to the top of
the flywheel-end iron, what are the paths of the 2 ports in the mount
point? (My engine came with the filter tower already removed & the mount
point taped over.)
Thanks,
Charlie
