First time poster. I put an Elite E2X on my 2015 Silverado 5.3 at 7,015 miles a couple months back. I now have 10,100 miles, and the can has not collected a single drop. A few days ago I actually had to uninstall the clean side separator as oil was leaking out from around the separator cap in the fill reservoir. I have double checked that everything is connected as the directions detailed, and that the inlet is even/slightly below the PCV outlet so that gravity can help out. Has anyone else had this problem? I have seen on this forum, and many others where in as little as a few hundred miles these things start collecting a couple teaspoons worth of gunk. I find it hard to believe that I ended up with a perfectly efficient DI engine......Thanks for any guidance in advance.

I would never buy a catch can for my truck, I would rather just do a top end cleaning every oil change instead.

My question to you guys getting this much liquid in your cans, how much of that is water/steam vs oil? How were your engines broken in? How frequent do you do your oil changes?

 

Since day 1 my truck has never been allowed to idle. It's not good for rings and it's not good for engine cooling. I'm either driving or it's shut off. If my food takes more than 30 seconds in a drive-thru, I shut my truck off.

 

I'm wondering how much of this "condensate" that you guys are collecting is due to poor ring seating or broken down oil. I have 38xx miles on my truck and not even a trace of film behind the throttle body blade. :dunno:

Like I said above, I've gotten about 16 ounces in a little under 10k miles. Its without a doubt mostly oil. I purchased my truck with 57 miles on it so I have no idea how it was broken in but I drive it aggressively as I hit redline atleast a couple times a week :driving:

 

I've changed my oil at 2200, 5450, 8200, and 12450 miles with full synthetic Mobil 1 and I try not to let it idle very often but it typically sees 2-5 minutes of idling per day.

I'm in the Hot Ass South so all of mine is oil! I am a Machinist and have built engines for years so it was broken in right an oil changed at 100, 500, 700, 1000 miles. and I don't eat drive thru bullshit and sure as hell wouldn't wait 30 min for it!

I'm up nort' here in da great white yonder called Minn-e-SoTa ;)

 

I did my first oil change at 1k and I intend on 4k mile changes after that. My truck when new was never allowed to idle so as to keep pressure on the rings at all times. You can say what you want about knowing what you're doing when breaking in an engine, but evidently to have that much blowby like you guys are seeing, something isn't right.

 

By the way, everything is in the details. I said 30 seconds, not 30 minutes of idling in a drive-thru boss. :)

Maybe this oil catch can business is a bunch of snake oil? :)

 

 

Could be. My 2006 Cadillac CTS 3.6L, the Elite catch can captures about 1 oz of oil every 100 miles. The PCV port is poorly designed and GM never felt the need to address it like they did with the pickups. On my 2015 2500 6.0L, the catch can captures about 4-5 oz in about 5000 miles. Not a terrible large amount, but still not going to the intake and messing things up over time.

how much oil does your trucks use between oil changes. just wondering if you use a quart , is half of it in the oil catch. I do oil changes every 6000 miles and my truck will still be on the full mark

Well up in Minn-e-SoTa you might be able to shut the truck off to prevent it from idling, but down here in Floriduh that just is NOT an option. Nothing quite as enjoyable as a black on black truck sitting in the sun when its 100 degrees outside. :devil:

Thirty seconds would be brutal, 30 minutes might be fatal. If idling a vehicle hurt engines, then every vehicle but yours would have a bad engine.

On both my Caddy and my Silverado, the amount of oil they use between oil changes almost mirrors the amount the catch cans capture. Both engines, the amount they actually "use" is minuscule. A couple of oz, tops. But the catch can capture a LOT of junk. The Silverado, the can captures maybe 1/8 qt over an oil change interval, the Caddy, now that is a PCV oil slob... the can captures about 1 oz every 100 miles on average. Both of these instances, it is almost identical to how much the oil level drops.

      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

      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.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
