Oil catch can (not your typical redundant questions about OCC’s thread)

[Cobra Jet]

So we all know:

- there are many varieties and styles of aftermarket S550 oil catch cans….

- the many redundant threads on here about “is it worth it to add one or not”… or “there’s no need for a OCC”…

- the theories, tech, and ideology behind oil catch cans and their function…

This thread is NOT that thread…

—

What I want to know is:

Is there an S550 oil catch can that is designed to drain back into the oil pan so that the user never has to open it to drain it?

If not, then if anyone designs a new S550 OCC with oil pan drain back properties based on my/this thread and that conceptual idea - please feel free to add me to the design trademark/patent elements and consider me as part owner of this specific S550 OCC concept and its new functionality. Hit me up on PayPal with 10% of each sale…. Thanks

I just want to point out I had that thought when I bought my OCC back in 2020 so I think I deserve half of your 10%

The amount of times needed for servicing the OCC really doesn't bother me but I have thought of this.

However - and have in mind that I am no engineer, motor specialist or have any deeper knowledge of ICE - but I imagine that the things to have in mind is if there is any sort of vacuum/pressure in the oil pan. It might not be much but it cannot be a straight hose from OCC to pan. Also there is a possibility/risk of exhaust gasses getting to the oil pan and if that comes with some sort of pressure it could do something...

Again - I'm no expert but that's just what comes to mind.

But I got an offer for you @Cobra Jet ! You can drill a hole in your oilpan and in you OCC and I'll transfer you $15 for a couple of connectors and a hose. THen you can see what happens and report back

Every OEM solution that has been designed this way has lead to problems, just look into it a little bit.

The best options are to either run one with manual emptying, or not run one at all.

You do not want one that empties back into the oil pan, for the simple fact that it not only collects crankcase byproducts, but it also collects condensation (water).

it must be manually drained.

There is an option for the Ecoboost:

I remember reading about that one but could not remember who made it, I myself would not want the oil from my catch can draining back into the oil pan. To many unwanted contaminates in it to create unwanted issues down the road.

vendors claim the oil tests don't show any water or fuel in the oil

 

[Buldawg76]

Water, fuel and dust/dirt are introduced into oil with normal engine operation, water from condensation accumulating inside the block on normal heat cycles of driving the vehicle, fuel from blowby past the rings during engine operation so if it happens inside the block it will happen in a catch can since it is seeing the same heat cycles and fuel vapor from blowby. Dust and dirt do find their way into the crankcase past the air filter and crankcase breather filters.

The moisture will be mostly evaporated out of oil if you normally drive car for 45 minutes or more at full operating temps all the time but if you make a lot of short trips of 15 minutes or less it never fully evaporates and continue to build up leading to internal corrosion.

Fuel blowby never is fully removed from the internals of the block and oil and is why you do regular oil changes to remove the contaminated oil.

Can it be emptied back into the crankcase, or is it too risky with dirt, etc.?

It can but I would not recommend it for reasons in my post above. You are just adding any contaminates and dirt/sludge that will accumulate in the catch can back into crankcase and oil supply.

Why would you want that? The catch can catches all sorts of junk. The oil is usually black inside. I don’t want that in my oil pan.

 

[ArgentumS550]

I would say that due to the small amount of oil, at least in my case, it's not worth draining it to the pan. Plus, one time mine was a tad bit thicker and I wouldn't want it possibly clogging up the drain hose. If it's collecting more, empty more often.

Also, I'd think that whatever is in the oil vapor that is captured, it would be the condition of the current oil status, not any extra contaminants (unless you're short tripping and moisture is accumulating, as someone said). If it's collecting vapor after an oil change, it'll be vapor from that clean oil. The same if it's used 7500 mile oil. It is vapor, after all, and the OCC's job is to cool that vapor down so it condenses and is trapped in the can. The oil filter is cleaning the oil of most particulates.

Lots of OEM oil separators on the market for various manufacturers, most of which are built into the valve cover. - none of them really work very well. Why would you want unburned fuel, condensation and contaminated oil to go back to the sump?

Random question. Does motor oil have a certain amount of wax in it like diesel fuel? I've always wondered if the white substance in the catch can is wax. Any thoughts?

It’s condensate
