This is a write up on installing an ADD W1 oil catch can on a 2014 5.3 Denali with a few thousand miles.   I like the RX can but after some research, the ADD can had good reviews as well. so fo

Well this issue is not specific to our trucks. If you look around at any other car/truck forum everyone is having the same issues. Over on the F150 forums, this is an issue on both the 5.0 and the 3.5

It will approximate your oil temperature. A little less, but it's getting it's pass through air right off the valley of your engine.

yeah I guess that makes since, what ever the oil temp is, is how hot the catch can will be, I should of known that, lol thanks

This is why it doesn't really matter where you mount it in your engine bay to try to take advantage of cooler spots. The internal temperature of the can will still get as hot as the oil temp and crankcase gases that it's mostly a futile effort to try to locate it in cool zones.

 

The theory makes sense though, it's the execution that doesn't. I could see if you built some type of refrigeration box for the can that tries to dramatically cool it down, that might make a difference in what the can catches.

That stainless steel pad stuff gives me the eebee-jeebee's. One little piece of that stuff in the wrong place would make a mess. Sure it's a longshot, but still...it ain't made to be filter material in an engine. Stuff could break off...vibration, pressure pulsing, etc..

 

Totally agree. It's not designed for this purpose and you know what they say about excrement occurring.

 

Otherwise, I like your selection of the Mann product. You do not need any fancy machined aluminum part for this purpose, especially with the weight it entails stuck out on a cantilevered bent bracket like most of the installations here seem to have. That is going to vibrate (I'd NEVER install anything like that in any of the "vibrator" trucks!). It's too much mass stuck out too far, and connected to a mounting point not designed for this purpose. Those long hoses are unsupported through most of their length. Those brackets will break. Right at the bend. You watch.

 

Second point: Why does everyone want the can to be mounted in a "cool" location? That makes no sense to me. If it's "hot", the water, which appears to be the main component of what these capture, will simply evaporate without any ill effects. The oil has a far higher evaporation point and will remain in the can, therefore it won't have to be drained so often. Here is another advantage to the Mann product -- it's plastic. Lower thermal mass, lower heat transfer = more water evaporated back into the intake. That translates to more flexibility in mounting location too. There's no problem draining that little bit of water back into the sump either. 15 minutes at full operating temperature will evaporate it and send it through the engine like it's supposed to.

 

And a question for Spurshot: what did you do with the return/drain tube? Is there a convenient location for it to connect to to drain back into the sump?

 

One last question for others who've done this mod: Do/did you see any significant (for the lack of a better term) oil consumption in your engines before you installed the can? I'm still on the factory fill, but there hasn't been one bit of consumption visible on the dipstick (always measured hot for consistency) in 4K miles. If you're actually pouring "cans full" of liquid away, and it's actually oil in there, shouldn't you be seeing measurable consumption?

Has anyone tried to incorperTe stainless steel braided lines? I just ordered the add w1. still waiting on the delivery of my truck...

 

Also, any warranty issues? Or any foreseen warranty issues?

It is a oil/gas/water mix. Colder temps results in more water. I keep forgetting to send off a sample for alalysis....been dumping it on ants....

Does anyone catch can make a hissing sound?

Yeah, it's more than likely from your hoses partially collapsing. I'm used to it now

I tried fuel line and pcv line both had a suction sound had to go to hydraulic hose to stop the sound its quite now. Need to get flexible hydraulic hose it has a cloth like coating the rubber coat is very stiff will work just hard to work with.

Looks like I'll be needing to emptying the catch can more often,, it was completely full today, but my question is what I the sludge like stuff at the bottom that want come out when I tip it over to drain it, brown in color and very think, need to take a rag to it to wipe it out

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
