I cant comment b/c I have not checked my out going pipe for oil..i will when its time to empty the can..I realize there are other PCV outlets and the OCC doesnt solve for all of them..but mine IS catching oil and did so almost immediately..I would rather this than automatically directing it to the intake track like stock does..

if there is an issue w upgraded turbos and the PCV set up..then i suppose another solution is in order..i cant comment on this either since I am stock turbos..so it doesnt apply to me

I am simply pointing out that my can does work..and there are many others who have theirs work too..its unfair to just blanket statement that it doesnt work...

So if my RR OCC is collecting oil... what does that mean?

Self contradicting much?

Dude, the point of this OCC is to capture ALL of the fumes. Not 70%, not 80% not 99%, but all 100% of oil.

If you look at your OCC and you see oil being there you CANNOT say that yours is working fine, because chances are, for every oz of oil captured, your engine ingested equal amount.

Quit arguing this. Go take a look at your OCC, disconnect both tubes and see what't the deal.

It means that it is capturing SOME oil blow by. The only way to be sure that the OCC is getting ALL of the fumes that pass through its portion of the PCV system is to look at the outgoing pipe of the PCC. If it is dry, then OCC is capturing everything it sees. If it is greasy, its not doing a lot.


Also, as repeated above: the OCC is attached only to one portion of the PCV system. There are two more check valves responsible for relieving PCV pressure when cruizing and deceleation. If you have not modified those, then your valves are STILL getting dirty.

The only issue i have seen w RR is the plastic fittings which degraded over time and started leaking

2. The vast majority of the OCCs out there are sitting on top of the hot turbos and their internal design relies on oil fumes condensating on the walls/mess/screen of the OCC. Guess what, that ain't happening if the OCC is as hot as everything around it. You need to put the OCC in a location where the fumes will condensate. However, this requires extra long tubing which in return causes a massive pressure drop. So the OCC attached to long ass tubing, regardless of the diameter, will be rendered useless or at the worst: causing pressure changes in the PCV system.

3. Hell, our cars already come with the best OCC available. It is called an intercooler. I have absolutely no problem taking mine off and washing it with denaturated alcohol twice per year. Same goes for the valve cleanup job.

Thanks for the post.. Admittedly I am pretty ignorant in this area.

It would seem to me though that the OCC's are catching something though. Your not opening them up and having they be completely dry.

Realistically there is no way that using the "condensing" method that you are describing in an engine bay without some sort of direct cooling method. Your going to have to use some sort of filter or mesh.. what I am uncertain about is whether this filtration itself adds to pressure drop.

Doesn't the BSH use what is basically a fine steel wool and the AR use a micron filter?

[pHo_e92]

i have the same issue to but its not always. im fully catless to but even when i had my stock exhaust on it did the same thing. just a couple puffs of smoke when i come to a stop. i cant smell it and when i tried to pull over one time it didnt do it again so i wasnt able to check to see if it was blueish.

100% really?> ok guys to each their own..

I can say that b/c i have had mine for 1000 miles and its collected the same amt urs has in 16000 miles or kms..

Its just logic..

There's only one way to determine if a OCC is working or not, and if you find oil in the outgoing hose you can be sure that your OCC does NOT work.

If you excuse, I don't have the time to explain this to you anymore, so I really hope that you got it now...

That simply means that your engine produces more blow by than mine. If anything your piston rings are in worse condition than mine. Still don't get it?

Filtration adds more restriction..you want to catch as much oil as possible but still have a system that breathes properly.

BSH uses only a perforated metal baffle..no filtration...the AR uses some filtration media I believe

That's what I've been preaching, but apparently in NY they have problems comprehending simple concepts.

With 17K miles I HIGHLY doubt that..you are just speculating and guessing idly trying to justify your point..its cool stay stock..BSH sucks..

True. Have you actually seen the insides of the BSH can? I have. When I got mine brand new, I put a green laser light in it. That perforated metal baffle you speak of does not go in the entire length nor width in the cylinder. It is suspended about 1/3 of the way infront of the airflow. Its more like a splash screen than anything. Air has the ability to pass around it like very easily.

I made a commend about this last year. BSH came on board, claimed their design was flawless and never posted back. Then I created the thread which proves the BSH OCC is crap and they are nowehere to be found. They won't even respond to PM.

I wonder why....

LOL! The RR OCC is not a OCC. It's a toy.

My only concern was keeping oil out of the intercooler. Ive been running the OCC and Methanol since practically day 1 on this car and I bought it new.

I think mine has about 17K on it. It was leaking at the seals on the catch can itself in the beginning but i fixed those.

In retrospect I may very well just remove it when i get around to it. Again, my only concern was keeping oil out of the intercooler.

This is what I got after 5K

FOLLOWING ARE THE SPECIFICATIONS OF A PROPERLY WORKING OCC:

- It should have as short hoses as possible.

- It should have an inner diameter greater than 16 mm, through the whole system.

- It should be placed in a cool place. Not above the turbos.

- It should have a filter that manage to filter the air, without restrictions.

- It should be 100% gravity feeded, which means there should be no uphills in the system.

- It should not have any oil, dirt or moisture in the outgoing hose.

Ooh , I've "seen the light" long time ago. I just needed time to prove that the BSH OCC is junk, that's all...

I may be regretting this but here goes...

Big Tom, those are great goals. I 100% agree with you. However none of us have successfully found an OCC except for apparently you that come close to this.

That leaves the rest of us that do not have time to research and make a custom OCC only two choices: use whats available or go back to stock.

Now with that in mind 100% dry outlet hose is certainly ideal, but even if my OCC only catches 10% of the oil vapor that passes through, that is still 10% better than stock with regard to preventing oil from passing through.

On the issue of back pressure I offer the following example (again). Balance a straw on the tip of your finger. Now put 4 inches of water in it. The backpressure we are talking about is the same as the pressure at the tip of your finger due to the water. Make sure you ignore the weight of the straw.

I am not trying to be a smart ass here but I am a little tired of the OCC bashing when the offered alternative of going back to stock is 0% effective relative to any OCC.

Big Tom, how about some kits or at least a DIY. I would rather be on the constructive side of things since we all have a common problem.

[Express]

tibra1, all these accusations an no real hard facts.


i am also still wondering your secret suspension setup since its "soooo much better" than mine.
