I have filled up 4X since I installed the adapter and not a single ounce of 2-stroke oil is missing from the reservoir.

I am also reading that pre-mixing oil with gas in the fuel tank is clogging our fuel filters so what the hell do I do?

DarkBrew

Basic questions. Someone has to ask...

Where did you mount the reservoir
Did you get the air out of your oil lines?
Is the adaptor installed correctly?

don't drive anymore without adding premix to your tank - at least until you find out what is wrong .....
Don't worry about the fuel filter - would you rather have a fried engine or a clogged filter (which won't happen anyway BTW )

The oil reservoir is mounted where the oem washer fluid would be.

I did bleed the oil line 100% but there might be air inside the OMP and adapter.

I am highly confident the adapter was installed correctly.

Well both would be very bad.

A clogged fuel filter would lead to fuel starvation issues while in boost no?

I think everyone who installs the sohn mod is worried about something being wrong. If you search my posts, I asked on this forum pretty much what you did.

The oil lines out of the OMP were brownish in color and I am using RP which is purple... when I saw no purple in the lines I thought it wasn't working. But the oil lines are stained from the hot oil and they will always be brown in color.


Also I wouldn't worry about air bubbles, they will rise up in the hose leading to the OMP.

When I asked what happened if the omp wasn't giving oil to the engine, the reply I got was the engine would die within 20 miles or so. Since you've filled up four times, you should be OK.

If you want to be sure your engine is OK, premix for the time being, until you're sure oil is flowing.

oh, make sure the cap on your fluid container has a pinhole or something in it to allow air through. without it, it will build up a vacuum and prevent oil from draining. I use the oem washer bottle, it's lid already has one.

Thanks for you're reply mysql

What made me start to worry is when MazdaManiac said the OMP should consume (400:1) 1quart for every 100gallons of fuel.

turborx8

iTrader: (1)

Yeah I am using a washer bottle as a reservoir so no vacuum will build up at all.

mysql101

I did 1 complete quart in 1,000 miles before the turbo was removed. Usually I see 1 quart per 3k miles.

Wow, that's barely none at all.

What are you using to pre-mix? I heard your oil filter was clogged when you replaced your fuel pump.

mysql101

I use the mazsport fuel pump. So the filter was just replaced to fix the issue.

1 quart in 1,000 miles is a lot. Not a small amount.

I don't really premix anymore. I do use a few oz of fp60 per tank though.

turborx8

iTrader: (1)

So you stopped premixing because the clogged filter scared you?

MM seems to think premixing is required to keep our engines happy.

mysql101

if you're in boost and your filter is clogged and you don't get enough fuel in boost, you could lose your engine.

It's not premixing that keeps the engine happy, it's making sure it gets enough oil. MM's omp doesn't seem to inject as much oil as my omp does.

It seems like I am in the same boat as MM.

I wonder what he does to keep his fuel filter clean. Maybe If I pre-mix 6oz of Idemitsu and 2oz of FP60 it would help to keep my fuel filter healthy!

mysql101

i was doing 4 oz of rp 2 stroke syn plus 2 oz of fp60.

I've got a Sohn adapter sitting here in the garage, waiting for a free moment to be installed.
As I've noted elsewhere, my current OMP doesn't "P" any more, apparently. I haven't seen a drop of oil consumption on the last two motors for nearly two years.
(While it is true that the OE lines get stained, the "bubbles" of oil do move - I verified this by pushing compressed air into them and watching them move. I also verified that they do NOT move on their own by marking several of their positions with a Sharpie and noted that their positions were unchanged after several days.)
So, I was going to swap the pump for another that I have laying around and put in the Sohn adapter at the same time.
However, I have a concern -
The OE OMP is indeed a pump, but it sees oil at normal engine pressure (30 to 60 PSI or so) before it pumps it.
The Sohn adapter just sees oil at atmo since it isn't receiving oil from the engine oil pump, so won't the flow be significantly less than the normal OE flow?

mysql101

Well, you saw my washer fluid bottle was right about on the top marker line that showed 1 quart. The lower line shows the end of 1 quart...

I've driven around 550 miles on the new transmission, and here's the washer fluid bottle now:

mysql101

I think the OMP just sucks in a small amount of oil every so often. I don't think it relies on pressure, but I'm just guessing. The fact that my oil tank is decreasing should be evidence that it's working. I also checked for leaks and I don't see any. All the hoses are completely dry.

I am trying to figure out a way to use my sohn adapter with my turbo. Since I have a front mounted turbo the manifold comes up under the OMP by the stepper motor control plug. My manifold is wrapped in DEI exhaust wrap. I have re-routed all the wires and plugs to give the most clearance possible and zip tied them so they wont move. The downpipe is also DEI exhaust wrapped. When the sohn adapter is installed it pushes the OMP out by about 1"(the thickness of the adapter). This is my problem. There is little to no clearance between the position sensor and the downpipe. I think I can get everything to fit and I will be heat shielding the OMP but do you guys think the exhaust wrap and heat shielding will be enough to keep things from getting too hot and melting? If not, does anyone have any suggestions? Anybody know if the the position sensor can be turned upside-down?

Jason - do you see any bubbles in the clear lines and, if so, do they move from day to day?

Tommy - That heat wrap stuff is really good. However, if the MOP stuff actually touches, it will wear and it will melt.
If its just really close, you can add one more layer of radiant shielding (the aluminized type, facing away from the MOP) to the side of the MOP and it'll be fine.

mysql101

the only time I had bubbles that I can recall was when the OMP adapter was first installed. Because the hose slopes downward, the bubbles eventually all rise and nothing but oil remains.

I can check again tonight to verify, but I'm pretty sure this is how it is.

MazdaManiac

iTrader: (3)

I mean in the clear lines after the MOP, not the adapter feed line.

mysql101

ahh. I'll check tonight for you.

OMP may see some oil pressure from normal feed, but the OMP flows so little oil that not much pressure is required to keep the input source full.

With the Sohn Adapter on, gravity pressure is adequate to assure continuous supply and to prevent pockets in the lines a long as the tank is 6 inches above the adapter.

As for the initial air pockets, they only result from residual air that gets in the feed from installation and should not appear again once cleared - if they do, your lines are not sealed and/or flowing properly (enough tank elevation obove OMP).

It does take a while for the air pockets to fully work there way through - mine still feeds 1 qt every 3000 miles and it took about 700 miles for the air pockets to work themselves all the way out.
