yup, can just barely see it... that would work well enough... would like to do my catch can too... or just drop the catch can completely and route it down below under tray. It's annoying having to clean it out and the end of each winter due to the condensation... seems to be the only time it fills up.

 

I actually removed my catch can today, this pic is like 20 min after taking it off lol. It had a level indicating tube and it didn't have a drop of oil in it.

If you decide to use this type of container check out rotaryman13's thread for all the part numbers from us plastics.

 

Can you take a pic of your setup? I am going to use a Weapon R as my combo catch can/sohn reservoir.

 

My latest and likely final SOHN reservoir. Excuse the dirty engine bay

Is it just me or is your catch can HUGE!

You should rip it all down and paint that bay now

 

Yeah my catch can is large but not huge when you look at other turbo FD's etc. but for a reason, my last one was too small and caused my turbo to smoke. That issue is gone since this has gone in.

Yeah I wish I had painted my engine bay when the engine was out. But oh well that is what touch up spray paint is for besides the engine will come out soon enough I am sure,

 

You turbo guys and your problems, bunch of cry babies.

Sell me that tray

 

Here is my
SOHN container/ catch can in the factory battery location (battery was relocated to washer bottle position using the RE-A relocate kit, then put into the boot)

2 in 1 can, 2 liter capacity each,

The side with the cap is the SOHN side, running fitting and SS lines to the SOHN OMP (MOP). Top of that is a hole and vacuum hose with a filter on end for pressurizing the tank.

The other side is a Baffle oil catch can,

Both side has a drain plug at bottom, originally ran a hose to see fluid level but 2 stroke kept leaking from the holes so i removed it. With the 2 liter capacity i check maybe once a month using the spare washer bottle cap.

Tank is secured using L brackets onto my custom tray,





Sorry if its abit dirty =/

 

Has anyone used a dual purpose sohn res/catch can?
I tried searching but only find posts of using a catch AS a sohn reservoir.
My idea is to use one can as both, so any oil headed to the intake is dumped into the sohn reservoir and injected.
I know injecting pan oil is less than ideal, but the amount mixing with the 2 stroke will be miniscule.
Any thoughts or does anyone know if it has been tried?

 

I wouldn't do it . The foul goo i see coming out of my catch can looks pretty ................ foul and gooey . One sure way to clog up your omp system IMO .

 

Yeah I thought about using my SOHN reservoir as a catch can. But then when we emptied a friends catch can I changed my mind because of all of the water in there.

 

How long had it been sitting in the can?

Could that have been due to condensation building in the can since it has lots of empty space as it fills?

Since I am getting ready to install both mods, maybe I'll run a test system for a while.
Utilize the stock omp system for 1000 miles or so while running a mock up of my sohn reservoir with a catch line running to it. Then attach the reservoir to an actual catch can instead of the sohn adapter with a controlled drip.
Run that through a couple reservoirs full of 2 cycle and see what the oil looks like after.
My thought is that both of these issues could be due to how long the catch sits with the oil being exposed to minute contaminates before emptied.

 

The catch can gets mostly oil vapor and condensation....any large amounts of oil are a rarity.

So basically you are going to get very little actual oil...and much more water...not what you want to be mixing into your 2 stroke oil. Not to mention the volume of air that will end up mixing into your reservoir

Not a good idea......destined to fail miserably

 

Correct me if I am wrong, but those using the Sohn adapter are using Premix at Idemitsu Lubricants America Corporation in their Sohn reservoir, or are you using an actual 2 stroke oil? If so, what 2 stroke oil?

 

The premix is an actual 2 stroke oil, meets jaso fc ratings (highest available in japan) for 2 stroke engine oil

 

do we need to have a breather hole for the sohn tank? without a breather hole the tank would be in 'vacuum' and is the omp able to 'suck' the oil down?

 

Use a vented cap or breather hole, otherwise there will be no oil flow.

 

Both containers included in the Epitroch sohn adapter installation kit include vented caps.

How often are you guys cleaning your catch can and how often do you fill your reservoir? Obviously the second part of my question depends on the size of the reservoir and your driving habits but I am curious.

 

My apologies for necroing an old post, but I just installed my SOHN Saturday and was curious how you guys are protecting your oil lines running against that steel clamp on the radiator hose. Also, are any of your oil lines wearing in any way? Is it that huge of a concern? I just want these tubes to be safe for as long as possible.

 

My four clear-ish lines seem to be really heavy duty. No issues. And my engine is so much happier with the SOHN and the mix I'm running...which is the top end Amsoil 2-stroke synthetic mixed with berrymans b12 chemtool at a 2:1ratio (2parts 2stroke.)

 

Injecting a cleaning solvent with the 2 stroke wouldn't be my first choice. I could see doing it for a very short time to clean out the pump and lines.....but can't see it being a good idea all the time

 

Hmm...been doing it for quite some time now. That particular amsoil is so viscous and concentrated that adding the Berrymans was the most sensible solution to keep the stuff flowing. It's been two years now and 20k, engine has 73k on it now and is still running massively better than the preceding 10k before adding the SOHN. ;-)

Maybe on the next batch I'll change it to a 3:1 or 4:1 ratio.

 

I installed the Sohn adapter today and I noticed the pinching of the injector lines between the coolant pipe and the hose clamp. There didn't seem to be any other choice with the routing of these lines and I haven't seen any warnings from other RX8Club members, so I'll hope for the best.

 

I recently made the discovery that the feed to the sohn adapter from the 2 stroke oil resevior is a gravity feed system, does this mean that there needs to be absolutly no slack in the line for continous feeding to take place, or is vaccum created during operation?
