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?

Posted

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
Posted

Would transmission cooler hose cut down on the hiss?

I used transmission line and havent heard any noise. Been on a few months, dont even know its there.

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

    • Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.  
    • New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.
    • No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.
    • Your safety is of utmost importance, @joshua1221, and we understand the importance of having all your lights working in your truck. If you have not already, we highly encourage you to bring your concerns to the attention of your local GM dealer. They are in the best position to diagnose your concerns as well as confirm the compatibility of the mirrors with your truck. Additionally, we would like the opportunity to explore any way we may be of assistance.

    • - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
