Oil catch can?

You don't need the check valve.

 

Why not? What makes you think this? I paid for a catch can with a check valve, all I got was the catch can.

 

 

It does have a check valve. It's attached to the fitting coming off the cc.

 

 

And I don't think so. I can blow air through the tubing and the can without any restriction. And from my research, it looks like the videos put out by RX show them having a check valve in line with the hosing on the can.

 

Also, if you look at this picture, posted by Crf450r420 on page 25 of this thread, in post # 367, you can clearly see the check valve in-line with the screw type fitting on the right side of the can. Mine did not come with this part.

My dealership said my catch can wasn't needed and wouldn't catch anything. I opened it in there shop after 2,000 miles and let it run on the floor. Lol

So, I added a second output fitting to my Original RX catch can. I had been emailing with the RevExtreme folks about the benefits of a dual output can, and they were gracious enough to send me the par

Are you saying yours does not look like the pic? My Rx cc looks just like the pic and has the valve.

 

Correct. I am missing the valve. Seen here.

Has to be an oversight. They should be able to ship that out.

 

I figured as much. But didn't know why people said the check valve wasn't necessary. It helps keep even more oil vapor out of the intake.

Yeah OK... Do the Other cans come with a check valve?? NO THEY do not... It's really for boosted motors and HIGH HP BUILDS that have a lot on crank case pressure and blow-by and I'm 100% positive your motor is not one of those builds. So no you don't need a $2.00 valve. This was confirmed by Tracy.

Youre missing the point. I bought something that said it was supposed to come with a valve. I didn't get the valve. I want my moneys worth. Yea it might cost $2.00. But its the principle.

 

And every video with Tracy I see installing a catch can has the valve on it....

I have yet to see any "stock" camaros running RX catch cans with check valves just for reference mine included

Well I can only hope my order from RX comes with the check valve although on a side note the good news is I order it last Wednesday and it arrived Friday so it was pretty quick to me and I order it in summit white so will post once installed on Monday since PO is closed today.

Your right my friends 15' Stingray does not have one either. I might just experiment with my truck and take my check valve just to see why it's needed.

Just ordered my rx can. I see most of you mount the can on the brake booster. I was thinking about putting in near the extra battery spot. I see the concern with temperatures but will it really be that much of an issue? I've read through almost the entire thread. When it's negative out here I see running into the same issues whether it's mounted near the back or in front.

The cooler the can the better it will work as more of the evaporated water/oil will condense on the side of the can. I wanted to mount mine to the low side ac line to keep it cool, but it was to much work to get done in the time I had to do it.

The check valve doesn't keep oil out of the intake it keeps back pressure from a turbo charger from going through the can in reverse and pressurizing your crankcase thus blowing out the oil seals in the crankcase. You don't technically need the check valve because you don't have a turbo but I agree, you paid for it and it should be in there as an extra layer of protection. I would call them up they should send it out to you free of charge. Just a minor over site.

      Ac not keeping up

      By Aimatdeer · Posted

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
