I would like some help with identifying the various openings on my
engine.  This engine was built by Bruce Turrentine with his aviation
mods.  I just want to make sure I know where to connect everything up.

On hot-side-a, there are two plugs.  Is 'B' where the oil metering
pump went?  What is 'A'?  The exhaust system was built by Jerry Hey.  I
will report sound level numbers as soon as I can get the engine running.
Yes, Item B is where the oil metering pump is mounted. The round "thing" near that is the drive arm for the pump, and it rotates/drives off the front accessory gear under the front cover. The SMALL hole just to the left of the drive arm is the engine oil feed to this oil injection metering pump. If you are not going to use the oil injection pump (or not use ENGINE oil for the oil injection), I would have to say that at a minimum the oil feed needs to be plugged (if bruce didnt do it) and honestly the best approach in my mind would have been to remove the drive arm before remounting the front cover. To do that now would involve trashing a gasket/seal

Item A if I am correct is the turbocharger oil RETURN. This simply drops oil into the oil pan below. If you arent turbocharged, you can block this off with a blind flange made out of scrap steel/aluminum. You also can use it for an aux oil return, an oil fill (prolly a SLOW oil fill..) or anything you would want to do which would involve draining into the oil pan.
On plug-side-1a, I'm pretty sure the 'WATER TEMP' sensor is the famous
sensor sometimes incorrectly used for oil temp, but what about 'D' and
'E'? (Note oil filter block has been removed.)



D is oil pressure and or temp. Factory uses it for oil pressure.

E is hot water out to the heater core (car use). I havent figured out if I'm gonna cap it, tap and plug or what.
 
G goes into the water jacket. It extends all the way to the bottom of the engine, in the middle of the outer edge of the water jacket. It is plugged on factory the several engines I disassembled. No idea what goes there.

'C' appears to be a vent (for the oil?).  What do I do with it?
C is crankcase ventilation - connecting to an air/oil separator wouldnt be out of the question but I dont know what everyone else is doing.
 
Also on the back side near the flywheel, barely visible in this photo,
there is a line that used to go to the water pump.  I will either have
EWP's or a mechanical pump on the side of the engine.  Can this line be
connected near the water filler cap?  

On plug-side-2, I know where the Oil lines go, but do I have 'IN' and
'OUT' identified correctly?  Also, is the proper setup to connect oil
out to oil filter to oil cooler to oil in?

Oil flow should be from 1) oil out to the 2) oil cooler to 3) an inline filter if equipped to 4) oil in. 

If you use an inline oil filter, remember you MUST use a bypass block
on the oil filter pad. Oil WILL flow out one of those holes and needs
to go back IN the other.

Is 'F' where the oil return for the redrive goes?
F is not on my engine. It appears to be an aftermarket tap that should empty into the oil pain. Redrive oil return is a good possibility.
What is 'G'?  It's plugged off, so I probalby don't need to know but I'm
curious.
G goes into the water jacket. It extends all the way to the bottom of the engine, in the middle of the outer edge of the water jacket. It is plugged on factory the several engines I disassembled. No idea what goes there. 

Are 'H' and 'K' the Mazda oil temp and oil level sensors?
H is an oil temperature probe but if I understand correctly it serves ONE purpose and was not integrated into the factory engine controllers. It triggered a "cold start" function of some kind on equipped engines.

K is an oil level sensor and if I remember correctly the switch closes (goes ON) with a very low oil level.
 
Hope I was of some assistance.
