PCV Breather Hose and Catch Can Kit for EA839 2.9T/3.0T is Now Available from 034!

Why are worm gear clamps provided? Why no Oetiker clamps? Just seems strange. Also, I just learned my car didn't come with DRC caps installed. Damnit. Ordering those, now ($5 a pop).

Worm Gear clamps are provided as they provide sufficient clamping pressure for the application. Oetikers are not used as most people do not own an Oetiker Clamp Tool, and they are single use clamps.

You'll find that having the hoses easily removable from the check valves makes installation much easier.

If you twist it counter clockwise as far as possible first, it should come off much easier. Just pulling in the position it is, felt like I'm sure to break it but twisting did the tick for me.

I got the instructions for removing the PCV fitting off the intake tube from APR, when I installed their CF Intake.

Step 10:

Remove the PCV connection from the front of the metal turbo intake pipe. While pressing in on the connection towards the engine, run a pick around the inside of the attachment to loosen the fitting, then pull the connection off the metal inlet pipe. Be careful not to damage the inside of the connection with the pick.

For reference, see page 13 of their instruction manual:

https://documents.goapr.com/d562cfef...82e208a495.pdf

That is a very nice description of what to do. Compared to 034's instruction which reads:

"The one on the turbo inlet is also mildly annoying if you’ve never
removed it before… it’s quite tough to remove. No real hints, just
rotate and pull. It’ll need a good bit of force to come off, which is
normal. Don’t be afraid of putting some muscle into it."

LOL

Yeah, been there, tried that. Broke the plastic elbow piece. You might get lucky if it's a warm-climate or high mileage car, but I will be using the pick next time. Thanks

Anyone installed theirs and getting a strong oil smell after parking in the garage for a while after driving? No visible leaks, all hoses are clipped on and snug, and catch can plug and dipstick are tight but garage smells strongly of oil.

[NJS5]

OK, I’ll ask: what are DRC caps?

While I don't have this is it possible one of the check valves is backwards?

I checked both by blowing through them and both are flowing in the proper direction per instructions. It is almost like after shutting the car off it still bleeds fumes back through the intake as it cools down and it is coming from the intake box. No smell while running.

[Hibnah]

I just did the breather hose replacement. I pulled the stock one out and did the blow test. The stock one seemed to work just fine. Yet I decided to keep the 034 installed either way.

Cleared my codes prior and it’s been about a few weeks and never once has the old code came back. So this looks to have solved my issue even after checking the stock one for operation.

Thank you

[DutchK23]

just completed the breather hose install..the 034 instructions and this thread helped. I had the APR CAI installed already so turbo inlet was very straightforward the NORMA fitting came apart quite easily ....i did notice small amount of gluelike/motor oil substance t that end of the OEM pipe (perhaps early evidence of failure?) I did not notice any oil smell after driving..very satisfied with product...thanks to the 034 folks

[jdm-v35]

So no one else gets an oil smell(only after sitting in an enclosed garage of course)?

I've had the catch can installed for about a month now. I have not noticed any oil smell while parked in the garage.

Thanks. I will take a look around again to make sure everything is correct, but no smell while running and no CEL's. Valve directions were checked 3 times. No visible leaks. I seems to just vent for a bit after sitting in the garage during cooldown then stops.

[ontunerow]

Finally got around installing the 034 breather hose. When I did the test on the OEM one, when blowing quickly and strongly, the valve checks seems to function as expected. However, when I tried to blow more slowly and lightly the air did pass through the opposite direction. Did anyone try to do such a test and found similar results? Just wondering if it's expected or it's an early sign for failing.

[spacecase]

For people having issues removing the stock pcv hose from your turbo inlet, try disconnecting the PCV and throttle body hose and turn the hose to be straight up and yank. I’ve had to remove this hose too many times and this tip I found online is the easiest method.

I am getting the oil smell. Noticing it in the garage after its parked after driving... nearly positive I have everything installed correctly.

I figured I can't be the only one! I went back and triple checked everything and made sure it is all tight too. Only happens after being parked in a sealed garage for an hour or more and the smell builds up during cooldown. If its running it doesn't actively emit the smell. In an open area, it doesn't emit enough to be noticeable.

I emailed 034 just to see what they say about it and I will post it here. I don't mind the smell.. makes it feel like more of a true garage haha. But I do want to make sure it isn't a problem...

Agreed!! I mean its not a pleasant smell lol but also want to make sure it is not a problem or defect. Thanks for replying and please do let me know what they respond with!

[NJS5]

Hummm, waiting to see what 034 says before installing mine. Seems odd with everything installed correctly.

I don't have any smell emanating from the hoses or connections or directly in the engine bay even while running. It almost seems like during cooldown fumes seep into the intake pipe and out the filter or something during the temp change.

Heard anything back from them yet?

Heard anything back from them yet?

I sent them a few pictures of my setup and around the actual can, this is the response I got:

"After our Engineering Team reviewed the provided photos, we didn't notice evidence of leaking, seepage, or poor connection(s). If there are any other points of concern, please try to capture some additional up close and detailed photos, and I can pass these along to my team. The only other thing we would want you to check for and confirm is that all the O-rings are in good condition and are not damaged/pinched/missing in any way. Please also scan the vehicle to double-check for error codes, as a damaged O-ring/leak will likely cause a code to appear, and we can better diagnose what may be occurring with a code."

So I will scan the vehicle at some point today and send it over to them.

I am guessing it is just an aftereffect of installing the can. I also triple checked all my connections and smelled around the engine bay near the catch can and have no visual leaks and cannot smell anything around the new parts/connections.

True! It's not that big a deal, I just don't want it to cause any issues.

[034Motorsport]

Pending any discoveries from your inspections of the connections/seals, a small oil smell can be present simply due to the fact that oil vapors and liquid oil will pool in the catch can itself, which is semi-open to the environment when the car is off through the intake tract/intake filter. Where this oil is normally consumed by the engine as it passes through the PCV system, it is now being captured in the catch can.

This isn't abnormal nor something to be concerned about from a reliability standpoint, as long as it is confirmed there are no connections/o-rings compromised in the system that could be introducing a pcv leak elsewhere. Based on your checking of the connections, you should not have any concerns.

Thank you for the reply. I pretty much figured it was just the fumes escaping during the temp differential/cooldown period into the intake tube but guessing it is more prominent because the 034 valves flow better.

[jtbss4]

I installed the breather hose on my S4, after a month i had a look, and noticed oil all over it.. seemingly coming from the PCV connection. I took vids and pics and sent to 034.. they responded saying its basically normal and nothing to worry about. to me it seems like the 0-ring is not sealing things very well. How can oil seeping out not be something to worry about?

If the OEM part doesn't end up with "oil all over it" then I would say that its NOT normal.

I have the catch can kit, but have not installed it yet because I am waiting to receive the S34 intake I ordered so that I only have to deal with the connections once (fewer chances for me to break something). Once I get it installed I'll have to keep tabs on it to see if I end up with a similar experience.

[B6_Dolphin]

I ordered so that I only have to deal with the connections once (fewer chances for me to break something).

If you use a 90-deg pick tool on the PCV connection to the intake, just insert the pick underneath the ring of the fitting, and trace the pick around the fitting as you pull on the fitting, the fitting will separate easily. The other breather fitting that connects at the bottom of the intake tube is a squeeze-type connection as you pull-off. That one takes some finger strength!

Pick Tool I used:

Thats exactly what i thought. It really gives me hesitation to even use it, i'll probably just sell it. I thought the reason behind them coming out with a new PCV breather hose/catch can kit was because the OEM fails or is faulty..and they had a fire in one of their test cars. very odd that their position with oil seeping out of the PCV as being "normal" yet it mentions nothing of that in the product page.

034Motorsport has offered PCV & Breather Hose products for 20+ years, dating back to the B5 platform. Silicone has been the preferred material choice for thermal longevity and precision fitment. Silicone can have very minor sweating of vapors that permeate through the material, albeit in incredibly small quantities.

This high-quality silicone hose is engineered to be suitable for this application, and the amount of sweating that you see is absolutely normal. Based on our extensive testing and development of these products (on the road and track), we have not seen this oil sweat to be an issue or any cause for concern.

We are looking into adding an additional liner to this product in the future to eliminate the superficial sweating, so if we do move forward with that and anyone has any concerns regarding their kit, reach out and we will take care of you.

I have also seen this on other platforms from different brands. Definitely not uncommon as long as its not excessive.

Thanks! Appreciate your follow-up. I just installed the OCC this weekend on my RS5 - guess when the time comes, until the drain line is made available, I can use an extractor.

Oh, and since I had to go back to the 034 page to d/l the install instructions - did you happen to see the price increase? Wow.

I doubt you would have to extract anything before the drain line becomes available... then again, who knows how long before they release it, if ever.
