catch can yes or no? Answer inside.

Also have two college engineering degrees and am a self employed engineering consultant working with most of the car makers in Detroit.

You post questions my intelligence and abilities. Sorry, got that covered. This shit happens dude! Understanding the injection, PCV system, and intake system...makes perfect sense why and how it happens. Catch can not required...but helps.

First off never intended to question your intelligence dude, and where I don't have 2 engineering degrees I do have one. Worked for 12 years in the performance industry designing fuel induction parts and nitrous systems. Drag raced for many years as well and maintain our vehicles, but only have three. That being said I think we can agree that we both know our way around a car and understand whats going on. I will stand by what I said. An engine that has that much oil in the intake track has an issue. Either a PCV system that is not working correctly or something else causing that to happen. And I will agree that catch cans are not required, but cause no issues. No harm meant and sorry if I offended you. By the way, I think we may have had this conversation before.

I find it amazing on here how everyone that has a catch can, empties oil from it (a couple times between changes) gets it but yet, the ones that don't have one are so quick to criticise us. All that oil was definitely headed to the intake, I don't understand how that isn't clear
If you don't believe it (catch cans) then move on and let the people that are asking and wanting info to see and hear from us that do !

No one is criticizing you, or at least I am not. If you have one and like it great, but your engine is not going to go boom if you don't have one, and that's not what many on here believe. If you have one you will catch oil if it is plumed correctly. Or difference of opinion is on how much advantage there is to catching that oil. They by no means hurt in any way.

CAIs and Catch Cans, the religion and politics of Camaro5. Like I said, we need a mandatory moratorium on these two subjects for a minimum of six months to build friendships and bridges again.

To answer what we missed, most automakers have recently lowered the warranty period on the power train due to some of these issues. GM in fact just dropped from 5 year 100,000 miles to 5 year 60,000 miles (most GDI engines will be running rough, hesitating and having misfires by then so this reduces a huge liability for them)

Most any LS3 or L99 owner just needs to simple remove their TB and shine a bright light inside to see the severity:

Now, the average owner that just jumps in and drives and does not log KR and pay attention to excessive oil consumption, this will most likely never be noticed in the old port injection LS engines, but this is doing NO good to anything, and the detonation and increase KR means your engine is always running at less than optimal timing advance. Power and MPG are down then, and this is what causes the ring lands to clog and prevent rings from sealing properly compounding the oil consumption and blow-by issues. As for throttle bodies, plenty of examples of the amount of build-up on the blades and throat. This disrupts flow at the transition when the blade is opening resulting in hesitation and stumble depending on the severity. So dealers also do regular TB cleanings for this. Here are pics to show as well:

All of what we are sharing is for the benefit of the car owner wanting to care for their vehicle the best possible. For those content to ignore and leave theirs as is we have no issue with you. You are more than welcome to ignore what we share. We have no desire to fight, argue, or interfere with you and ask the same in return. For those that have used these products for years all know the benefits first hand, and many more want to learn.

We try to contribute all sorts of beneficial information to the members whether related to our selling our products or to just help a member with something unrelated, and the effort you have put into harassing us and our followers this past week has far surpassed what is allowed by forum rules.

Our apologies to the other members that had good questions and want to learn and share. And our thanks to tunaman for his threads sharing the experience of using these and being present for the videos of the installs after our group buy promotion.

Now, let’s get back to the technical questions and discussions. We here at Elite Engineering USA have taken some big steps this past year in investing in the latest most effective design to date to address the unique issues all GDI engines experience.

We have released new and improved products to this line, and we have invested in having on staff one of the few true experts in the engineering and design behind all types PCV systems, proper crankcase evacuation, and how to implement the correct solution no matter what the application from family cars to 1200 HP plus mega boosted builds.

We continue to show our commitment in the past to always be at the front of the technology involved VS the dozens that just "sell" whatever, and we have also made the commitment to educate, and share information and knowledge with all as we have now entered a completely new era in vehicle engines, and they are nothing like the old port injection engines everyone has experience with, but NO engine does well with oil entering the intake air charge. Air and Fuel are what the combustion chamber should contain for combustion; nothing good comes from oil being present.

So keep the good questions coming all, and ask about other solutions some see pushed that can harm your engine over time, we will cover it all. Education is the best way to sort through opinions and misconception, and we have made the commitment to you the members here to provide just that.

Do it right, do it once, Elite Engineering.

Wow. Didn't mean to start this, lol. Thanks for yor replies elite and others. My intention was strictly to demonstrate the result I had on my 1LE. I'd seen many threads pro and con on Catch cans, but nothing conCrete pertaining 1LE with factory oil separator. As I said, my 99 had well over 200k miles when I sold it. Ran fine. I'm not happy with the blowby on this car as I intend to keep it a long time. I will be getting a catch can. My car, my opinion, and most importantly, my wallet, lol

Exactly. I have the Elite, it does what it's supposed to. Will my LS3 die without it? No. Does it prevent needless crap blowing back into my intake? Every time I empty it, my answer is yes.

If we could find a way to direct this "fighting spirit" on CAIs and catch cans to stupid stick on sh.t people "decorate" their Camaros with, the world would be a much more aesthetically pleasing place. I didn't know if I should laugh or cry. Saw a Camaro with deep dish rims and Autozone stick on fender vents the other day.

All I know is that when I pulled the duct work when I put the new air filter in, there was a puddle off oil in the duct. Again, the Traverse has 225,000 miles on it... That's a hell of a lot of miles. Still runs perfectly, burns no oil, gets decent mileage. I have record of every oil change and the longest I ever stretched it was 7000 miles and that was due to a long trip. I was even more shocked when I pulled the TB... No way did I expect it to look like that!

Here is a picture of the pcv system... And it's clear the intent is for the oil vapor to go into the duct between the filter and TB. The black hose comes from the block. Goes into the top of the check valve, and into the duct. Hot oil vapor meeting cool air is going to change from a gas to a solid. Thus you get raw oil. This is a horribly designed system, but low cost and meets emissions requirements.

I have a catch can on my 1LE and it catches the vapor and converts it to raw oil like it is supposed to do. I believe in it. Why don't automakers do this? Regulations and cost. Working in the automotive engineering world, let me tell you, they nickel and dime things to death and cars are still very expensive.

I hear the 2016 Camaro has a factory catch can system on it. I have not confirmed that, but if so, it's proof GM recognized the absence of one as a flaw.

It's proof that the 2016 Camaro V8's are a direct injected engine, which was not the case with the Gen 5 V8's. Again, its your money and its your car. With all the oil present in your Traverse intake, you still comment that "Still runs perfectly, burns no oil, gets decent mileage". Again its everyone's call, they cause no harm, and if your engine is direct injected, I think it becomes a much bigger concern not to have one.
