New Alternatives to OCC's being adapted for MS3!

[Breakdown81]

Hey Everyone-

I just wanted to throw it out there that a new part for our cars is about to be tested. I gave Ming Tai, owner of ixizconcept a call yesterday and spoke with him about his AOseparator. You can read about this device here:

IxizConcept

the information is located under the Power tab at the AOsep link.
The short explanation is that it acts as an oil catch with a bonus. No maitenence. It separates the oil vapor and air that bypasses the pistons under boost, separates the two and returns the oil to the crankcase keeping your intake track clean.

Ming has been developing parts for the subaru community for a while, and was excited to hear about my interest in his product. I should be recieving a unit for testing sometime in the next week. pics and a review as well as an installation procedure will follow.

Assuming that the product is successful on our platform and there is enough interest in the community for more. We batted a few ideas around, Ming would be interested in producing a short throw shifter, an engine torque damper and pretty much anything else the community would be interested in having.

There is one thing i could really use the forums help on though. Since I am In Los Angeles and Ixizconcept is located in Lawrenceville, GA, its rather difficult for me to get my car out there for him to directly take a look at. Id like to ask the forum members who are in or near that area to please send a pm if they would be interested in taking their MS3 out to Ixizconcept to get measured. Thanks for taking a look at this post and please let me know if you'd be interested in this product or any other that ixiz could develop for us. Thanks.

just a note,

i wouldent want my latest OCC contents going back into my engine.....

interest +1

[MazdaspeedGT08]

Very interested break! keep us updated

[numbnuts22715]

Ive heard about this before.. Idont remember who posted it though.

[superskaterxes]

ok well as far as the new explanation goes i completely understand it. but my concern still stands. i def do not want that crap from my CC going back into my crank case. because we have a high oil dilution from the DI i dont think it would be a bad idea to add a little oil once in a while. this will raise the oil/gas ratio and keep things running smoother. for the record my turbo smokes like cheech and chong and after emptying my OCC i still dont see any noticeable decrease in oil between changes. otherwise this is a great product and def serves its point!!!!

I do not have an OCC, but have seen what comes out of them. And at first I would have to say, "hey I don"t want that crap back in my engine".
But consider this,
the fuel is not likely coming from the intake.
direct injection engines seem to produce high fuel dilution in the oil.

My point being that, it is likely already there in mine and your oil.

I have seen a similar setup on a turbo Diesel common rail, we never had a fuel dilution issue, but we changed the oil ever 50 hours of operation. (mobil 1 syn is cheap when you don't have to buy it)

I was all about the OCC a while ago, but I would like to see more engines that "coke up" / "carbon up" the the cylinders. Also knowing how those examples were driven, would be great.

Finally, I am not too worried, as I am keeping mine mod free, and if the time comes (hope not) talk to Mazda.

So you want to consciously put more of that crap back in? Isn't it smarter to remove it and replace with clean oil if you are "consuming" too much?

[red07]

Therein lies the dilemma of OCC vs AOS: one separates the gunk out better, but then you lose oil constantly. If you run low and forget to add oil...

The AOS will minimize oil loss, but then you run the risk of contaminants....

[Breakdown81]

im pretty sure that once the oil gets returned to the crank case it ends up being pumped through the oil filter a second time. I'll have to check on this and let you all know. However, I really don't think that ixiz would have lasted long in the subaru community if his product let contaminated oil lubricate moving parts. I'm supposed to speak with ming this weekend so expect an update monday or tuesday.

[Silver Ecstasy]

I like the clutch adjustment thing that guy sells! Pretty smart!

[car46999]

Even if you drained out of your OCC 1oz of fuel each time, I think all that you are seeing is what is a portion of what is there.

It would be great if someone could do oil analysis before and after OCC/AOseparator install. To see if it changes.

I am neither for of against either of these "solutions". I believe that they don't fix sh!t. I would say a OCC would be a better option, but I don't see a need for one on my car.

I would think if you run low on oil you OCC would have exploded.

Breakdown81
IxizConcept may be a great company, and I am not bagging on them.

The oil is filtered each time it is pumped through the engine. But filtering does nothing for fuel dilution. Because the fuel bonds to the oil and changes the viscosity of the oil.

Oops, let me clarify. If you continually dump your OCC then subsequently forget to top off, you're going to be seriously low if you are a heavy footed driver.

[mlassek]

a lot of the crap that you find in you OCC is from moisture that condenses and accumulates in the OCC and hoses. so if this new product just constantly re-directs the blow-by oil everything should be fine. esp after it runs through the oil filter.
i am interested in seeing how this mod will set up with our cars

[Breakdown81]

Thanks for throwing that in mlassek, i was going to add an update concerning what you mentioned, but it seems you've beat me to it.

So, if you haven't read mlassek's post, please do. Then continue.

The AOseparator operates as a completely closed system, hence no outside contaminants (i.e. moisture and condensation, unfiltered air, dirt, metal or other particulates) can enter and pollute the oil. So in light of this fact and the information mlassek provided, the concerns some people have about introducing contaminated oil (like the stuff you find in catch cans) is unfounded and shouldnt play a part in a decision concerning the use of this product. You only are reclaiming the oil that would otherwise end up in your intake track as a result of blow by.

Im not one for dramatics but in this case i feel its pretty clear. Over time engine performance will be affected if you don't have some method of keeping vaporized oil from entering your intake track and contaminating your combustion mixture. Not to mention it could get caught inside your intercooler and gum that up over time.

Personally, I'd set up a one shot system that will automatically reclaim the vaporised oil and send it back into recirculation. I'm lazy and don't want to deal with emptying a catch can. So hopefully, this update has settled any lingering doubts about what this system actually is. I'll post again once i have the system in hand.

thanks for keeping up with the thread.

[car46999]

I am still going to pass on both of these options. If it does hurt my performance, I will simply take it to Mazda. That is the reason I am staying stock.
If it gets out of warranty, then I might consider one of these.

I am sure Mazda wouldn't like you plumbing back into the oil pan for the drain back, which is why I would lean to OCC. (that is the plan correct, to go back into the pan)?

I still say "I would like to see more engines that "coke up" / "carbon up" the the cylinders. Also knowing how those examples were driven, would be great."

I really think the solution is that Mazda should re-design a fixed PCV.

Later

Car46999 please re-read my original post, or go to ixiz concept and research further. No plumbing into the oil pan is needed to make this product work.

I don't see where it says the oil goes back into (other than it says crankcase). But that is quite vague, (could be anywhere on the engine) the webpage also was of little help. I see that it says no drilling.

So where does it go?

[car46999]

From you PM you have proven to me that you have no mechanical knowledge, and I will contact the manufacture.

Thanks ass.

[TRU-BOOST]

there is 1 problem with this device. it only works in 1 direction. the car pulls more oil into the intake anifold under vac. than what seeps past the PCV under boost. that why i prefer a CC. it will catch the oil being drawn in uder vac. and when you install it with a second PCV it will seal up perfectly not allowing any blowby under boost.
