Product Description:
Upgrade your failure-prone PCV breather hose with the high-performance, 034Motorsport Catch Can Kit, engineered for enhanced durability to capture crankcase oil deposits before entering your intake tract.

The PCV, or Positive Crankcase Ventilation system, on the EA839 is located on bank 2 of the engine (The right side of the engine). It is designed to ventilate the engine's positive crankcase pressure through a breather hose into the intake tract or charge air system. The 034Motorsport Catch Can was engineered to improve upon the factory PCV system, implementing a baffled Billet Aluminum Catch Can to trap crankcase oil deposits before entering your intake tract. The Catch Can Kit utilizes a re-engineered breather hose that plays an integral role in this ventilation system.

How Does the PCV System Operate? The Positive Crankcase Ventilation System, or PCV for short, works to remove excess pressure from the crankcase system and relies on vacuum from the engine's intake system to operate properly. This system operates with two components, an Air Oil Separator and a Breather Hose.

In the EA839, crankcase pressure is generated by the engine rotating assembly moving under normal operation, and can contain oil in the form of liquid & vapor, water vapor from condensation, and blow-by gases. The Air Oil Separator acts as a collection chamber for this crankcase pressure and oil, separating some, but not all of the oil and water vapor, allowing the oil to drain back into the engine oil pan. The crankcase pressure not caught in this chamber is evacuated through the breather hose to be ingested by the engine.

At idle or cruising while not in boost, the engine's charge air system operates under vacuum, drawing air in continuously. During this state, the breather hose utilizes this vacuum to release crankcase pressure into the charge air system through the connection just after the throttle body.

However, when the vehicle is under boost (during acceleration), this connection becomes pressurized, meaning it can no longer provide a vacuum source for crankcase ventilation. When this happens, a check valve in the breather hose closes off this connection, preventing boost pressure from entering the crankcase. At this point, the breather hose is able to draw vacuum from the turbo inlet connection, as this creates vacuum through a siphoning effect as the turbocharger draws air in through the intake.

Whether you are sitting at a stoplight or romping on a backroad, a properly operating PCV system is crucial for maintaining the engine's performance and preventing harmful pressure buildup.

Why is the OE PCV System Insufficient?
The check valves within the factory breather hose are an integral component of ensuring correct operation. However, since these check valves deal with the high temperatures of an engine bay and the transition between vacuum and boost pressure, they are susceptible to premature failure. When they fail, excess pressure can enter the crankcase, causing it to operate under conditions it was not designed for. In fact it's likely these are the same as what Audi uses on naturally aspirated engines, which makes them not up to the task of dealing with pressures associated with turbocharged engines.

As the crankcase of the engine is not designed to operate under pressure, it typically will find the path of least resistance to release this excess pressure. The seals and components inside your engine, which are designed to operate under vacuum, aren't built to handle this excess pressure. In some cases, the path of least resistance is unfortunately the oil cap, which can loosen and expel hot oil into the engine bay, potentially causing a fire.

Audi issued a TSB (Technical Service Bulletin) concerning this failure of the PCV Breather Hose as of 2020, though in our testing 034Motorsport has concluded that even the newest variant of breather hose is susceptible to failure.

Some other solutions on the market neglect the importance of maintaining adequate vacuum pressure from the charge air system and intake tract to ensure proper operation of the PCV system. Because the PCV system relies on these two separate vacuum sources under normal operation, removing one would prevent the crankcase ventilation system from functioning properly.

When these solutions remove the upper intake manifold as a vacuum source, it disrupts the PCV system's ability to vent crankcase pressure at idle or in a cruising state while not in boost. Because the crankcase no longer has sufficient vacuum pressure, seals that are designed to operate with this vacuum pressure can fail prematurely. This lack of vacuum pressure can also lead to the potential of pressurization of the crankcase system and engine damage.

Additionally, many aftermarket solutions have check valves that do not provide sufficient flow to accommodate the boost levels of Stage 3 equipped vehicles. These check valves are too small and this inefficiency can cause restrictions, resulting in reduced flow from the crankcase, causing crankcase pressure to build up.

During the development of the 034Motorsport Stage 3 Dynamic+ tuning suite, the development B9 Audi S4 experienced an unfortunate OEM PCV breather hose failure. This failure caused oil to be expelled through the oil cap and onto the hot turbocharger, immediately causing an engine oil fire. This failure was documented in our video Ashes to Asphalt, documenting the extent of the damage and how 034Motorsport was able to make the most out of the situation. Because of this failure, it made engineering a proper solution that was able to withstand the harsh engine bay temperatures and elevated boost levels of utmost priority for 034Motorsport Engineers.

What is The Fix?
034Motorsport began by benchmarking the factory PCV system for flow capacity and other check valves on the market to replace the flawed breather hose design. Due to this, we opted to engineer and develop our own proprietary check valves that offer fantastic restrictionless-flow capability when open, and create a strong seal when closed, capable of holding over 40+ PSI of pressure and dealing with the high temperatures this system is subject to. These check valves utilize a durable synthetic rubber diaphragm that offers high heat, chemical resistance, and a precise low-vacuum opening amount on the turbo inlet side, and a nylon ball check valve on the pressure side for superior strength under high boost applications.

The 034Motorsport Check Valves are housed in a high-flow, 4-ply reinforced & fluorolined silicone hose, specially designed not to collapse or inflate under vacuum or boost pressure. These silicone hoses are molded to allow the factory engine cover to be utilized with the 034Motorsport Catch Can Kit installed. The additional fluorolining prevents oil vapor from sweating through the silicone hoses.

The Billet Aluminum Catch Can is engineered to fit in line with the factory Air Oil Separator and 034Motorsport's re-engineered breather hose to capture crankcase oil deposits. The 034Motorsport Catch Can Kit allows the full PCV system to properly vent crankcase pressure while keeping oil vapor and liquid oil out of the intake tract, resulting in drastically reduced carbon buildup and extended life from the EA839. The Catch Can Body was meticulously designed to ensure it collects liquid oil and oil vapors through its vortex accumulator design, while still allowing effective flow to vent crankcase pressure through the intake tract as designed.

This offers increased reliability of the crankcase ventilation on the EA839 V6 at all power levels and an additional layer of protection over the standard 034Motorsport Breather Hose replacement.

034Motorsport engineers designed the 034Motorsport Catch Can Kit to be used with the OEM Factory Air Oil Separator rather than design a bespoke Air Oil Separator, as we found during testing that this unit provides excellent crankcase pressure control and is capable of supporting the flow needed at Stock through Stage 3 power levels without failure.

For added convenience, there is an integrated dipstick allowing for a quick and easy way of checking levels. The Catch Can also includes an integrated drain line that allows for service-free use of the 034Motorsport Catch Can, draining the captured oil back to the oil pan.

Why Do You Want a Catch Can?

The Air Oil Separator acts as a collection chamber, capturing some of the oil and water vapor present in the crankcase while regulating pressure. Any uncollected vapors are expelled through the breather hose, and the oil captured in the air oil separator is drained back into the oil pan.

As this crankcase pressure is evacuated through the breather hose and into engine's intake tract, the uncollected vapors pass through and enter the intake system. This can cause oil to pool within the intake tract, generate carbon buildup on intake valves, or be ingested by the engine resulting in dirty combustion.

The 034Motorsport Catch Can intercepts this uncollected oil vapor with an intricate baffle that allows the 034Motorsport Breather Hose to continue venting the crankcase pressure and water vapor into the intake tract to be ingested by the engine. Once collected by the 034Motorsport Catch Can, this oil vapor pools within its large body. This decreases oil in your intake tract, reduces carbon buildup on intake valves, and results in an overall cleaner combustion process.

As the catch can system is under 212*F, it allows small amounts water vapor to condensate and mix with the oil, resulting in a milky texture. This mixture is then drained through the integrated drain line back into the oil pan, allowing the water vapor to pass through the PCV system uninterrupted and be burned off in the combustion cycle.

Within the operation of the complex PCV system, this water vapor is intended to be burnt off during the combustion process. This small amount of water that is collected in the catch can drains back into the oil pan, re-vaporizes, and re-enters the PCV system to be burnt off without causing any issues.

Still in one piece and played with!
Color: Checkers - Dinos Bruto (Purple), Size: Mini
Very durable for my little King Charles Chewer. She's had it for a while now and all though the chewing phase has calmed down, she still can be somewhat rough with the toys. The little dino is standing firm. It was a battle she figured she couldn't win with Dino. Now he's a fetch/ tug o war toy that still gets a few nibbles.

DONT BUY THE ELEPHANT, ITS NO GOOD. but GR8 BRAND!
Color: Checkers - Elephant (Gray), Size: Large
The elephant toy had no trunk by the FIRST day! The elephant now looks like an angry Koala bear OR an angry trunk less elephant(whichever u want to say) I LOVE the donkey and dinosaur toys so I bought the elephant confidently, thinking I had nothing to worry about. I wouldn't have spent money on this knowing the trunk would be chewed off in a matter of minutes. My Bella usually chews but she has had her donkey and dinosaurs with the chew guard for MONTHS and there are NO TEARS OR RIPS even with her playing and chewing on them ROUGHLY all day. If you buy any of these type toys I DO highly recommend the donkey or dinosaurs ONLY. The elephant being chewed up in a matter of minutes really makes me angry that I ever spent the money on it. HAD I known it wouldn't be the high quality dog toy I'm used to from GoDog, I would've just bought a second donkey or dino! Now Bella doesn't get her new toy for the month (I try 2 buy her a new stuffed toy or 2 about 1 time a month whenever I have the extra money for it) I guess she will have to go without this month because I spent it on this now trunkless elephant/angry koala:( Whichever name you call it, it is now going to be trash. UPDATE! If you contact the GODOG company they will send one replacement toy for your pet! They also asked me my pet's size, breed and age in order to send the best possible toy! They sent Bella a snake that has held up Extremely WELL! It's great and so far is my favorite(and one of Bella's favorites) The snake has less sqeaky things in it so she doesn't have the drsire to tear it apart immediately to retrieve them by rippong it to shreds:) My updated rating is for the MANUFACTURER'S GREAT CUSTOMER SERVICE. The fact that they actually replaced it was good but the fact that they went that extra mile by researching the best toy match for my Bella was above and beyond! If you have a Godog toy that went bust right away, contact the manufacturer for a replacement. If you give them your dog's age, weight and breed they will even try to match your pets replacement toy with something that is better suited to your dog's chewing style. (Bella's style is destructive haha) Good luck, ya'll!

My Dobermans favorite toy to destroy, and one of our recommended picks.
Color: Checkers - Elephant (Gray), Size: Large
Ok, here's an honest breakdown review. I have a 6 month old Doberman who shreds every stuffed animal and dog bed he's come across. He's one of the worst chewers I've owned. We have tried a WIDE variety of stuffed toys. That said, this elephant is his favorite toy. I have ordered 4 of them so far, and just ordered another 4-pack on a buy three get one free deal. The elephant stands out above all the other stuffed creatures from goDog for me as to durability. Hence why I keep buying more. But they usually last about 2-3 weeks on average. In our house, the poor creatures are subjected to vicious, crazy, shaking of the head, helicopter type rotation. It' so hard if it hits your bare arm or leg it actually stings especially when its wet. Then the old, put it between his legs laying down, tearing at the legs action. The limbs are usually the first things to go over time. But they are each almost self sealing, so you clean up as little fluff and keep using it. Eventually the pup reaches the main body and finishes it off. For a normal light to normal chewer, one of two will get you a long way. For those of us resigned to having zoomie type manic chewers that need a constant supply of toys, 2-3 week durability is pretty sound too. I do not recommend the green cheaper monster. It lasted about 45 minutes. The free replacement took about 3 days. Hopefully this aids you in your decision!

Very durable for rowdy pups
Color: Checkers - Elephant (Gray), Size: Large
This toy has outlasted any other dog toy I have ever bought. I have one large and one medium dog who share toys, fight over toys, chew them to death and still play with them. It might be because it isn't one of their favorites. I don't know. All I know is that our house is littered with dog toys in different states of destruction and this elephant toy has very little damage. It has definitely been in the dog toy rotation. I had this toy for 2 months without any major damage. The day I wrote the review the dogs tore the leg off! I still think it is a good toy. Some toys lose the stuffing or squeaker the first day.
