3.3TT Oil Catch Can?

[jaccfrost]

Thanks for the information. Confirms that the dual inlet can isn’t the proper product to promote for this vehicle application. WoW! Even the dual can set up is questionable! Did you get the “check engine light”?

Obsessed with this subject! Just wanna get to the bottom of it...

This is was i intend to install, but Tork Motorsports made a OCC that looks like a factory and now that's what i want to install! check his video about it on YouTube if you guys wanna see it.

WARNING!!

This pic is for NA (Normally Aspirated) engines only, where there is ALWAYS negative pressure past the throttle butterfly valve.

If connected this way on a FI car you will literally blow up the system!

Checkout the Tork clip below. Very clear explaination how things work!

Hope someone can explain why they incorporated a check valve in the PCV line.
Is there an extra valve in the OEM line?? If not, why do we all of a sudden need one?

I would like to see a possibility to drain without having to remove the cans every time. As simple as a plug i can open on top where i can suck out the sud with a small tube will do..

(Dropped the question at Tork, will post the answer if i get it)

Finally starting to understand the whole system.....correct me if i am wrong.

Intake pressure negative:
- PCV opens up. Crank case actively vented, sucking oil/water vapour out. Relatively ‘large’ amount of air circulates therefor most residue collected through this line.
- Breather: To prevent negative pressure air ’sucked’ into crankcase through the breather line. ( this is why both lines on the same source will not work and the CEL might come on )

Under boost:
- PCV closed
- Breather: only vents out blow-by. On a new, well run in engine little vapour will come out but with added boost and/or older engine this will increase and thus increase the need to have a catch can.

Still strange there is no OEM catch can. Especially with the GDI system.
Because of the direct injection you do not have the injected fuel ‘cleaning’ the valves anymore.

No check engine light or codes. Just pushed the dipstick out enough to puke oil down the drivers side exhaust manifold. And agreed that they should “not” be selling a product “ promoting “ for a car that isn’t needed.

I don’t think the breather line on this car will vent out. It only allows air into the engines crank case while the PCV line in venting hense not allowing a vacuum to occur. That is “I believe” why the dipstick blew out when I had it hooked to the catch can. When I smelled the factory vent hose it had no signs of oil smell or moisture from venting out.

At boost PCV closes and the only possibility for blowby pressure to leave the crankcase is via the breather.
Check out the Tork video. They did not make a custom OCC for the breather for nothing. The double purpose of the breather line is well explained. WOT is mentioned around 2:10

I took another look at your video and your catchcan outlet is going to the inlet BEYOND the throttlebody and thus in the boosted canal.
You more or less connected your breather, through the catchcan, to the boosted part of the inlet iso pre-turbo. So you ‘boosted’ your crankcase popping out your dipstick.

I know that now.....

I been watching another area of a user who built a nice 500 dollar dual can setup and so far the intake can side is bone dry.

My own personal experience with a Hellcat motor, FI 392, Jeep SRT N/A 392- Both only used a single can setup plumbed pretty much the same. Ill do the same with my Kia till somebody can prove 2 cans are useful.. IE., Collection in the intake can of a substantial amount. Who cares about a few drops.

Edit: Bout half the can was normal for a 3k mileage oil change.

Searched online for a catchcan with an easier drainage. Stumbled on this one. Extra checkvalve, bottom drain that can be opened on the top and an indicator when tank is full.
Looks like a well designed item for a reasonal price. Just have to plug the second outlet. No need for that...

Cool but out of stock.

FWIW...my ADD W1 can did not come with O-rings for the hose fittings either and i ordered it directly from ADD. That being said, did YOU add some O-rings yourself? If yes, care to share the size to mitigate my having to take a fitting it and "test" them?

I did seal the threads with a healthy amount of teflon tape as well.

I don’t have the size off the top of my head but if you have a NAPA auto parts store close they’ll have them. Did you see my update to the hook up on the vent line from the drivers side!? Don’t! Just leave it as is and plug the second inlet port on the can, it doesn’t work for the 3.3tt as described

FYI the dual inlet CC does not work for the 3.3TT. Waist of time and money to use a dual inlet.

second that, they kept telling me to be patient and then after a couple of months of waiting for install info, I lost my patients and wanted to return them. They told me it had been to long. I was going to buy my exhaust from them, not now

Thanks, there happens to be a Napa right down street. Ill take the can in when i remove it in 800 miles for the first oil change and find some that fit.

I personally do NOT have the duel inlet as it was readily apparent to me that it would not work. i ordered two of the V3 cans with intent of putting one on each side of stinger. I passed on the breather side for the time being and will put the extra can into the wife's Sorento. I am not convinced yet that a catch is needed on the breather side yet. Hopefully those with them installed can advise IF there is any "crud" in them and after how may miles.

When i disconnected the breather line, i didnt smell any oil/gas like i did with the PCV hose.

 

[K8 Stinger Store]

The directions from K8’s vendors are incorrect on running it to the drivers side turbo intake. These cars need the vacuum to suck the vapors out of the PCV. Looks good to.

We apologize for the confusion, the instructions that were being sent out were for the 2.0T Optima/Sonata motors, and not the 3.3T Stinger motors, as the manufacturer did not yet have vehicle specific installation instructions for the Stinger yet. We have since pulled those instructions from the packaging when shipping them out.

FYI the dual inlet CC does not work for the 3.3TT. Waist of time and money to use a dual inlet.

I appreciate all of the work you have put into getting it figured out. If this ends up not being right for the vehicle, we will absolutely remove it from our Stinger site. We are waiting to see what the manufacturer comes up with, as they have been investigating the correct way to plumb the catch can. However, you may be entirely right, we shall see.

I'm sorry to hear this. We do have a 30-day return policy which is clearly listed on our site. We are unable to take back products ordered several months ago, when we only offer a 30-day return policy. If we can make it up to you by offering a discount on the exhaust, I would be happy to do that for you. I apologize for the inconvenience and hope we can have the opportunity to work with you again.

It is a dual OUTLET.....
This one could be connected both to the manifold and pre-turbo to provide suction with and without boost. But from one single source, the PCV. Question remains if the pre-turbo inlet suction is sufficient to open the PCV. If this is the case then with the addition of a T, an inline checkvalve and small breather filter this would be the solution for our car.

It is cheaper than the Mishimoto that is based on a filter that needs cleaning.

I believe in centrifugal. Professional seperators, be it oil, water, sawdust or blood all work by this principle.
