I really like what you said here because what most people don't understand when they just throw on a breather filter to the crank case vent, is that it needs to have suction to the intake in order to breath according to the amount of boost you are making. but my one question is what about the vent that runs along the back side of the engine to the intake...the one right next to the crank case vent......shouldn't that be put to a oil catch can also....?

Nobody should be running a common chamber CC for both sides, regardless of climate. The AGP can setup is the way to go, or run 2 separate cans, one for each side of the system.

Seems that guys are blowing oil seals!

^ this is exactly why I capped a port on my JUN BL can and ran it the same as the AGP catch can is run, and just vented my other PCV to atmosphere, car likes that MUCH better.

Personally I have said all along not to interconnect the two. The best way is two individual cans.

Agreed^

Some are saying here that it's best to have suction on the exhaust PCV side, why is it then that AGP simply runs a can with a breather on it on that side?

What's wrong with a one can system like Jun's? What are the dangers and what's going to break? I had a Mishimoto setup, now I have Jun's, I really don't want to switch again (I want to start putting money towards mods other than a CC setup and my exhaust ).

If you don't have suction on the PCV side then you are defeating the purpose of Positive Crankcase Ventilation. It lets the junk build up in the oil and internal parts of the motor. On the PCV makeup side you can get by with a filter on the can but there really is no need as the can will collect the crap.

Snoopy what happened to your can? Maybe pull that YouTube video...

If I run both sides to the JUN can and then run the JUN can to the intake, doesn't that create suction?

So essentially, AGPs breather can is not sufficient...

You don't want a lot of suction on the valve cover side.

I really don't know what the internal design is of the one can setups. But with the normal PCV system one side is open to intake vacuum, quite high, the other side is the make up air to replace what is being pulled out by the intake suction.

Throw the turbo in there that pressurizes the intake. The coupe uses a check valve to prevent the crankcase from building up pressure, at that time the valve cover side is seeing a slight vacuum from the pull of the intake air going through the charge pipe. It is nothing like the vacuum of the intake though.

My fear with a one can system would be over pressurization of the crankcase, leading to blown seals, and not removing the combustion byproducts (blowby) from the oil.

Yes it does, but the problem is that when your in vaccum you're supposed to be pulling from the intake manifold side PCV. An when you're in boost the check valve is supposed to shut. With it hooked to the turbo intake, it's just pulling vaccum all the time. It made my car run strange, shot my oil dipstick out of the motor and made strange "sha sha sha" suction sounds at WOT. Since changing the JUN to run from intake manifold side PCV>catch can> intake manifold. And capping the 3rd bung that used to run to the turbo side PCV, all these issues have stopped.

Huh. I've had mine on for like 3k or 4k km and I don't have any of those issues. My car makes a sucking noise at WOT but that's the AEM CAI. No CEL or anything, and my dipstick is still firmly planted in her.

The filtered Passenger side AGP can works by allowing the system to draw fresh air in, when running around in manifold vacuum, and to allow crankcase pressure to escape, under boost pressure.

The problem with this setup is that the fresh, filtered air goes back through a filthy catch can.

With the right check valves you can use the JUN BL catch can...sorry was in a meeting at work and wasn't giving it much thought to type at the time...

With the check valve stated as is IM...PCV stays

Block the crank vent...(thoughts?) and run the intake line to catch can

You can use it, but its not properly engineered, with a single chamber. If it was internally devided, it would be the Bee's knees. The Cat's meow. The Dogs Bollocks.

Hmm sounds like the best way is two dedicated CCs. One for each side. I'll use my JUN for the IM side and pick up a can for the turbo side. Any mounting ideas for a can on the turbo side?

Sorry for some confusion on this.

Diagrams and video was pulled to prevent others from installing those ways until I'm done investigating the potential issue. Dual Catch cans with a check valve is and always has been the safest method possible to install a CC setup on ANY car hence it's still up however the potential issue could occur even in this setup.

This condition would only be present in climates that dipped below -18c and has NOTHING to do with catch can contents freezing, it relates to an engine component that could even cause an issue without a CC installed.

Hyundai Canada has been made aware of this issue and it is being investigated actively.

Hyundai Canada has also informed me that breather style catch cans are not recommended and could cause undesirable opperation outside of the emmisions control aspect.

I'll update when I have more information or a conclusion to the situation. Thanks.

I rarely see below 15* Fahrenheit where I live, so I don't have to worry about this correct?

exactly because as you stated before the crank case need to have a suction on it in order to be effective.
