Oil catch can?

[Huetatos]

I dumped my catch can and only got about 1 ounce after 600 miles or so. It looks like its mostly oil if anything. Atleast to me.

[Jsdirt]

I've got about 2oz. of 95% water in mine right now. Did a 240 mile trip, towing 6k lbs. for half of it. Temps started out at 11°F, and got up to 38°F by the end of the run. Always get lots of condensation in those temps.

 

Haven't cleaned it yet. I'll have to measure it just for sh**s and giggles when I do.

Is the EE site the only place to get their cans or is there another location (retail or online)?

Elite has many dealers around the World...JDP is one, and ton's of others.

Smell it. It should have a very acid/chemical smell due to the different compounds along with the oil.

 

I take it your in a warmer climate? Below 45*F the amount of water and unburnt fuel increase dramatically.

Much warmer. Lowest it got this year was 40 but I installed it at 55+.

When I first took it out it smelled like gasoline but now it has an incredibly strong chemical smell.

Thats why you see so little water. Most all of what you are catching is unburnt fuel, sulfuric acid, oil, and soot/carbon/ash particles.

]Finally got around to cleaning mine out today. About an ounce - mostly water.

 

241 miles total, half that towing 6k lbs.

 

Sorry about the sideways pic - no way to fix it on this site for some reason. Nothing works.

This just about exactly 1,000 miles. Not sure what it mainly consisted of, but it sure smelled like fuel. I don't let the truck idle more than a couple minutes tops when it's started outside after work. From home it's in a garage, so hardly any idle time.

I would say average outside temp was in neighborhood of 30F.

[GDI Tech]

Cold temps will always create more water and more unburnt fuel. The fuel comes from cold start enrichment and IAT temps provide the PCM data for fuel tables, so the colder, the richer (fuel economy always goes down in winter/cold temps).

 

The water is due to the condensation in the crankcase and the water released during the intense heat and pressure of the combustion process. That is a nasty mix of compounds demonstrating just what would be left to mix and stay in the oil as well as what is ingested in the combustion process when it is drawn in.

Tossed my elite E2-X on my truck today. Went pretty smooth overall so no complaints. I mounted the can using the bolt that holds the washer bottle to the core support so it's nice and close to work with. I bent a piece of 3/8" stainless with a simple 90 and installed a 90 degree Swagelok 3/8" fitting in the valve so it now will drain easily just out past the PCM. Lots of room to stick a water bottle or whatever under it now. I used another Swagelok 90 with a stub of 3/8" tube to connect the hose that goes to my clean side separator. I have an Airaid tube so it's not the stock arrangement. Just stuck a 1/2" NPT pipe plug in it for now but I will snag a 1/2" steel conduit plug we use in transmitters at work so it will sit flush and look nicer.

 

When I popped off the throttle body there was basically zero oil in there..... just enough to make a mess on your hand but overall pretty dry. I can't complain lol. That's with 15000 miles of hard driving on my 2015's 6.2. Now I will see what the can gets in it.... I imagine from my findings it will be mostly water.

So I just did 540 mile round trip to Vermont and back home (plus maybe 100 miles of local driving getting ready for my trip) and I just emptied my catch can. It has easily 3 ounces of crap.

 

I have been collecting this gunk in another cup and i almost have 3/4 of a cup now. From what I can see when it separates, only a small portion of it settles on top as oil, the rest from what i can see is water and something else. I will take a picture of it another time when it settles. It seems not all of it is oil but other liquids.

Correct. The "mix" you trap should consist mainly of the following, and when let sit for several days will separate into different layers of each.

 

Water in cold climates is #1. Unburnt fuel #2. sulfuric acid #3, and oil #4.

 

Of course there is ash/soot/carbon also mixed in with it but that does not separate like the rest. Oil will always be the top layer.

 

Just seeing this and realizing before you took steps to actually trap it, this was being ingested into your combustion chamber. Even if it did not have a valve coking issue, just think how much that contaminated the A/F mixture.

Here was my most recent catch can drain.

 

 

[GDI Tech]

And all the average person needs to see is that. You do NOT want that running through your motor!

[HondaHawkGT]

What amazes me is that GM has a catch can in the works for the new 6th gen Camaro that is (supposedly) designed to drain back to the engine oil pan.

I totally agree when I saw it first pour out that how can this be funneled back into the engine. But then I realized no one wants to maintain their cars. They rather have someone else do it. So that's why the dealerships do this. I wish I just added a catch can so much sooner.
