This is my second GDI GM vehicle.  The first was an 08 Caddy CTS withe the 3.6 V6.   At about 40k miles, I noticed a puddle of oil in the intake tube.  I pulled it off and cleaned it.  While it was off, I notice the TB was oily.   Cleaned that as well.  Looked into the manifold.  It was full of oil.  Pulled the upper intake and cleaned that.  While it was off, I could see the intake valves, they were totally gummed up.  Spent another 2 hours cleaning that up.  I ordered a catch can the next day.  Everything stayed clean after that, at least until I traded it at 111k for this truck.  I used to get about 3-4 ounces of fluid out of the catch can every 4-5k miles.  The fluid was a combination of oil and water vapors so it looked like chocolate milk.

 

Therefore, I am sold on the need for a catch can on all GDI engines.  The new Fords went to a combination of port and direct inject, my guess is to combat this issue.

 

My old was was an RX, but I can't seem to find them anymore.

 

Haven't read the whole thread to see if it was posted yet, but RX is still in business and can be found here:  http://teamrxp.com/

 

The RX can and the Elite E2 are essentially identical.  I would buy one of those and go with whatever has the better price at the time of purchase.

I have had the Elite E2 and the UPR on my 2015 Silverado. The UPR catches more oil and the hoses and connections are 10x better than the Elite. I had to replace the Elite hoses due to them collapsing.

I think you'd be adding the oil either way.  The catch can just means you engine did not ingest it.

That would mean that the catch can somehow is removing oil from the engine that was not already on it's way to the intake, or you engine has worn in a bit has a bit more blow by than it used to.  I do

I wonder if the can would fit there with the stock intake?  Would the supplied hoses be long enough to go around that massive intake silencer?

Absolutely and I had hose left over.

Damn, RX is PRICEY now.  $450 to start and goes up from there.

Yeah they are.  I think mine was $299 when I bought it in 2014

Do you have adequate space under the can to access the drain and put something under it to collect the garbage coming out of it?  How does it affect access to the dipstick?

I added a few more pics. Still looks a little cramped in the pics, but it's really not. I can easily fit a standard water/pop bottle underneath the catch can for draining and accessing using the oil dipstick is also not an issue.

I have the Elite S2 on my 2017 Sierra. Definitely worth the investment! Install was very straight forward and didn't take long...............

I researched this in depth before I purchased. I decided on the Elite E2 without Clean Side Separator (CSS). The CSS is primarily for low vacuum events such as towing or a frequent heavy foot. I believe in these things and I get a fair amount of oil in the can which I’m glad isn't on my intake valves. Elite has been around a long time but they all are good and work on the same principle.

Do you have any pictures of how it looks installed?

      OCI, not when but why?

      By Atlas · Posted

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.

      I apologize, I missed this post, at risk of going off CURRENT TOPIC.   I'm not saying it is BS, I'm questioning how much information is being held back. GM is NOT going to spell out exactly every parameter in the algorithm. Liability, intellectual property, etc.    I'm not naive enough to believe that it is as simple as revolutions, coolant temperature, miles, time; are you?    I don't do irrational either, and boiling the OLM down to four simple values that I could code in an afternoon (I'm not a coder) is irrational - unless it suits your agenda to ignore it.

      Chris 21 I appreciate your constructive response. !!  😉😉😉   The 6.6 is gas.  Correct me if I’m wrong but by recalibrating the speedo you’re correcting the shift points of the transmission on these trucks.?.

      That is a huge misconception.     Bigger does not always equal safer.  Modifying does not make it safer either, with exceptions.   Think of this.  Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc.   37s and a lift?  Now you've affected your braking distances, handling and ride control.  You've raised your center of gravity higher.  Your front visibility is now obstructed more than stock, same for your rear.  Does it look cooler?  Yes.  Does it now work as good as it did from factory on road?  NO.       As for my mention of exceptions?  Say you had a sedan or crossover.  They typically come with all season tires.  If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle.  That is an actually improving modification.  My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size.  It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.
