Life After Installing an SOHN OMP Adapter

This may be a dumb question but I haven't really found the anwser I'm looking for yet. If you have a Sohn adapter kit, does the factory oil pump still work? Like, ive seen install videos and the pump mounts roughly in the same place after the kit is installed. So, let's say you run out of premix in your resovior. Does the factory oil pump still inject oil where the car is drivable? Or is pretty much deleteing it and focusing on the kit to create all of the lubrication.
I apologize if this question has been anwsered, but that's what forums are for.

This is the primary one of the reasons Mazda doesn't do it that way, plus most people would either consider it a hassle to always be checking and filling the tank or wouldn't and let it run dry killing the engine (and likely blame Mazda for making it this way).

Adding to the previous two replies:
The engine has two oil pumps.
The first is the main circulation pump similar to every other 4-stroke engine that lubes bearings and such remains unchanged.
The second pump injects specific amounts of oil into the combustion chamber and this is specific to rotary engines. With the Sohn adapter, it remains but the source of the oil it pumps is changed from engine oil to a reservoir you have to mount somewhere.

Ok, thank you. That clears it up a lot more. I have had 2 RX8's, but have never experienced with the sohn adapter whatsoever. I'll probably be looking into getting one. It just seems easier to check the resivor instead of having to check the oil every couple of days.

Read and learn a lot before any experiment. I'm sure you don't find any doc saying that the Renesis has two oil pumps.
Try to install the SONH reservoir on a low place, under the oil injectors and will see how many oil "pump" the MOP.

I have it and I use idemitsu 10w30 In the reservoir. The same in the pan.
There is something that shows me and it would be probably not noticeable without the sohn:
My dipstick level is increasing. Part of the oil coming from the reservoir and mixed with fuel is passing through the sideseals and entering to the oil system. That’s why my dipstick shows that it have more and more oil.

No, it is not. It's a positive displacement pump. If you give it fluid, it will pump it. By definition a positive displacement pump doesn't know anything about the pressure before the pump, so if you have a mile of hose before it, yes it won't pump. It's job, by definition, is to guarantee constant flow after the pump regardless of what pressure it's pumping against (within reason).
Mazda's own documentation calls it a pump. So yes there are 2 pumps. Someone with website called Essential Renesis Parts ought to know that
Do we really need to have an argument about the definition of what a pump is?

well it's a very low pressure positive displacement metering pump, but assisted by engine vacuum pulling in intake air at the oil injection nozzle to create to create a venturi-effect just like the one in the fuel tank pulls fuel from the RH saddle into the LH saddle.

If you try to do a fountain with 4 injectors you will never have the same level of water per jet. You have to put four levels to see the same water in the four jets. What means that omp makes a “perfect” first stage where the four tubes will have the same amount of oil.
#93
YEs. But that after the omp prepares the same amount of oil in each tube. The rest of suction comes from the part of the injectors and also is needed a hole in the reservoir.

Well it is vacuum dependent to some degree, so as an engine has issues in one rotor or the other and vacuum drops as a result it also compounds the situation with getting less injection oil as a result of low vacuum imo
A relief venting hole in the holding tank is needed regardless of how the system works

What does MOP stand for again?.....
Regardless of what you call it we all know what it does and nobody can prove if a SOHN adapter is worth it or not.
I get the theory side of it, nice clean oil for lubrication. But at the same time I don't run one and have had 50,000+ kms of beautiful boost without issue. It's a dead topic and as 9K stated ya'll are just regurgitating a bunch of BS from years before.

SOHN OMP Adapter Updates
Hi to everyone, New to the forum, but not to the Rotary.....
Quick question. Do we have any updates/concerns regarding the SOHN adapter kits.... i.e spark plug issues or oil leaks ??
or issues with turbo chargers (other than fitting) >>>???<<<
also would there be any benefit to using an Engine Oil Reservoir Catch Can +Vacuum Pressure Gauge rather than the supplied res. that comes with the SOHN kit ?????
thanks....
