[Elite Engineering]

First, an oil analysis will show, but have an in-depth analysis...the Blackstone base analysis most use does not go deep enough to show all. Our main Engineer has been working with one of the largest most respected oil lubrication company's in the US working on just this issue. Think about all I explained on how and why fuel and particulate matter getting past the rings and entering the crankcase.


Now, the LGX GM made some changes to the PCV system to reduce the amount of oil entering the intake air charge, and it is a vert detrimental change for engine longevity. They deleted using the intake manifold for evacuation suction.


Instead of incorporating 2 evacuation suction sources like we have done for years to improve removal of these compounds from the crankcase before it can mix with the engine oil (please watch this video, while very generic, it is one of the only accurate training videos on how a PCV system works, and the functions it performs):







Here is a picture of the engine, and I'll go over each of the connections/hoses explaining it all:





So, if you look at the picture above you will see on the left side of the air box a small hard line goes from one of the air box "mufflers" and slits into 2 lines that connect to the front of each valve cover.


That is the clean, or "Fresh" side of the PCV system where MAF metered filtered fresh air enters to make up for and flush the dirty, or "foul" (GM uses the terms Fresh and Foul instead of Clean and Dirty) contaminate laden vapors from the crankcase.


The line from the drivers side of the air bridge runs to the rear of the engine where it connects to the valley cover under the intake manifold. This is the dirty, or "foul" side. But, as you can see, it does NOT connect to the intake manifold!! It only uses the suction present just upstream of the throttle body, and that suction is not nearly strong enough to properly evacuate the crankcase, so even more of these contaminates that enter as blow-by are being retained contaminating the engine oil. Now, underneath the intake air box is a large diameter hose that runs to a "sound symposer" (a speaker of sorts, non electrical) that transfers the sound of the intake suction to the firewall of the engine compartment (Ford does this with the Focus ST as other brands do as well in there "sports/performance models". I think it is dumb, but only IMHO). This hose has nothing to do with emissions or PCV.


Now, think about what this means to evacuate even LESS of the compounds that cause engine wear from the crankcase brings us backwards in engine technology decades. Elite in the E2 and E2-X systems utilizes both intake manifold vacuum for evacuation at idle, cruise, and deceleration evacuation, and the area in front of the TB for evacuation suction (only strong enough when accelerating or at WOT to properly evacuate) when IM vacuum drops to unusable levels when accelerating or at WOT. So, we connect to the tube running to the rear of the engine (the "Foul" side) and that runs to the center of our separator. This MUST have a 1/8" fixed orifice flow control restrictor in that line for proper CFM of flow. One outer fitting on the can with checkvalve flowing away will connect to a T you install into the brake booster vacuum line right at the barb it connects to (there is a one way vacuum checkvalve inside that line and at the booster stock). Then we connect the other outer fitting on the can w/checkvalve flowing away from the can to the barb on the drivers side of the air bridge at the barb on the one way valve located there. This now transfers the PCV system to always evacuate and remove these compounds as soon as they enter as blow-by and are still in suspension. Once these settle and mix with the engine oil, they are there to stay for the most part as the oil filter cannot trap particulate matter that small or remove the fuel and water present.


The Elite systems also retain emissions compliance and maintain a closed system.


Now, the way GM does this does reduce the amount of oil mist ingested, but in trade greatly increases the engines internal wear and shortens life (look at you warranty period on the engine, notice how they have dropped the mileage coverage?).


Now, as for the oil being ingested, how many have actually removed your intake manifold and look? I expect none. Your air intake bridge will only show oil at 2 locations now on the LGX, and that is inside the "muffler" on the passenger side where the fresh line connects (remove air bridge assy and turn up to drain out that fresh side barb to see) and also on the throttle body blade itself. Remove the TB and look inside the IM with a bright light and you will see oil on the floor of the IM.


Now, the post that "has not seen an effective catchcan", you are correct. 99% of all catchcans on the market, especially cheap Ebay cans to even the most recognized names only trap from 15% to 30% of the oil and other contaminates from the PCV vapors allowing most to still pass through and cause the issues your trying to prevent. The E2 and E2-X systems trap app. 95% plus of these, and there is no more effective can on the market. Want to see this personally? Take any other can that vendors promote, and install the E2-X or E2 can inline AFTER the can doing its best first in line and drive 1000-2000 miles (start with both cleaned of all oil) and the Elite will trap as much or more as the first can in line....and that is AFTER the first can did it's best. Now, to be fair and accurate, now clean both cans again of all residue and install the Elite E2 or E2-X can first in line, and the other can your testing last. The E2-X or E2 will allow almost none to pass into the second can as it is doing the job it is designed to. And this is ANY of the promoted brands. It is not fair to just name these and make claims as we are biased of course, but if you do this yourself and share you will see the same results we do in our testing (and this is the perfect way to see personally with no need to trust any brands claims, see for yourself). We already know the results as we have conducted these ourselves or would not make such a claim. No other catchcan manufacturer (most do NOT manufacture their offering but have the same can labeled with their brand that is branded with a dozen or more other brands) has put the R&D into what works and matching it to your specific application than Elite Engineering. And we make these claims with the actual results you can personally validate.
