Oil/Air Separator Canister Experiment

[Jay In Milpitas]

Looking good.
I notice the flash point and viscosity have also increased.

Supplement: notes that Peter is of like mind. Must be something in military mind set

Solid results, JBFL! Looks like the 90 degree thermostat might be the ticket!

Yes, I hope so.

But this is far from conclusive; too many variables, not enough samples, no "control" vehicles.....

I'll have one or two more oil analyses to see if the results hold up.

I have hesitated posting about this air/oil separator catch can for several reasons:

There are less expensive ways to accomplish the same thing. You can purchase 3 or 4 stock OCS' for the price of the the replacement one.

The stock OCS functions exactly the same.

Where I have it mounted is subject to damage. It was the easiest place to mount it and I am still exploring alternate mounting positions.

I haven't finished exploring other catch can options.

However, I am convinced that some type of catch can, the stock RX3 OCS or a replacement, is beneficial for the health of your engine.

This is the Rutland Motors Oil Catch Tank from the UK







It is ~25 UK pounds. With shipping, and depending on the exchange rate at the time, is about $55 US.

The stock OCS from CSC is $13 US:

You can read about the catch can Here:

And order one here:

Before you rush to buy one, continue reading, then make your own decision.

The catch can is mounted in the same location as the stock OCS:




Since it protrudes in front of the frame, it is subject to damage from road debris, especially in off road riding.


Here is another installed photo:




The other necessary task is to close the hole in the air box. I used a 1/2" rubber cap, purchased at a local auto parts store, fastened with a hose clamp.






The first photo of the mounted catch can shows the amount of fluid collected after about 150 miles.

IMO, sending that amount of oil (60% +) and combustion by products back into the engine is not beneficial for the engine.

In previous posts I have mentioned the consequences of doing so.

Here is the stock OCS in a configuration that accomplishes exactly the same thing.....and it is nearly free. The only cost would be for the 1/2" rubber cap and hose clamp for closing up the air box.




You have to decide how you feel about releasing the filtered gases into the atmosphere, and what to do with the liquid collected in the catch can.

And as mentioned in earlier posts, altering the stock emissions configuration is illegal.

I make no recommendations.

There may be less expensive options to the Rutland Catch Tank, besides the stock OCS, that I have not finished experimenting with.

Smart ...like the way you say for experimentation only...

Great write-up jb. Thanks a ton!

Back to a much more simple and dated issue in this whole OCS thing....in the "official" position, the bent hose off the motor dang near kinks and I'm afraid that it will really stifle the vapor flow...which I would think may ADD to the fuel in the oil problem by creating a resistance in the escaping gases.

I've left Mrs. 2LZ in the "unofficial" position (factory set) and the bent hose is much more natural in it's shape. I think may leave it like that, plug the air box and then run the "filtered gases" out the backside.

Revisiting this whole thing.....I have 12k miles on my bike and have no more issues as I flipped it as shown in JB's pic(nice write-up)
And installed a fuel shut off valve barely cracked open to not allow buildup in
Tube.

My only issue as stated by previous poster is the "S" shaped crankcase tube kink
Which has a pin hole in it from crankcase pressure making a hard turn at that junction.

So I have ordered a new "S" crankcase tube but when I install it I am going to mount somehow to eliminate the kink.

I no longer have mystery oil level rising going on with suspected fuel as I had earlier experienced when my engine was young.

This thread never gets old! I'm currently venting back n2 the airbox with no noticeable issues....but this sure makes you think.... Bouncing these ideas around makes us all better owners, makes for enjoyable reading and banter and is why this site is the best forum for us.....well done to all
