Anyone installed an oil catch can on a Z28?

So why do we need a catch can or do you have a link to the answer?

I don't think he realized he was in the Z/28 forum. On the other forum they beat the catch can thing to death on the V6 and LS3/99 cars. With the LS7 we have the dry sump which should pull a vacuum on the oil system. The catch can is in the PVC system and people feel there is abundant oil that gets transferred to the intake through the PVC system. The idea is that it traps any contamination in this can that's in line. Then it won't go in the engine. If it does get to the intake it should burn it, again some feel this will ruin the intake and damage the valves. Your choice, but all these years I would think GM would add it if it was truely needed.

Right now on the SS forum there's a guy that can't get warranty work done on a blown engine because of a catch can.

Thank you. That settles it. No catch can for my LS7

I just took my car on the track for the firsdt time and had to cut it short because I have oil leaking all down the front of my motor. if I have no can am I seeing the results of it?

many thanks. super concerned and my local chevy dealer is clueless.

where is the leak coming from? was the oil cap tightened correctly? how much oil is leaking?

yes, would agree to have another dealer take a look.

ALL GM dry sump engines have issues with oil ingestion "burping" out of the cleanside line. As you can see, the main intake air bridge on the later ones has a cleanside separator from the factory where the cleanside line attaches to the inner radius of the intake tube. These fill quickly as they are small and no baffles or media inside to effectively trap the oil. Remove the intake tube from the throttle body and see all the oil inside the IM floor as well as the TB coated.


The SS owner is the first documented case in all the years and hundreds of thousands of users of proper systems EVER denied warranty, and the failure is a failed oil pump, not uncommon with an LS based engines as there are thousands of examples on the internet, yet not a single case before this one of a proper system like an Elite ever causing any issues.


Now, the drysump in 2015 GM added a "cyclonic separator" to help reduce the oil ingestion, but it does not stop any on the dirty side.


If you want the longest life and reduce oil caused detonation, then yes, the Elite E2 or E2-X system (the cleanside will not clear the hood due to the location of the oil sump tank) will improve the PCV system to not only evacuate during idle, cruise, and deceleration, but also adds a secondary evacuation suction source so under acceleration and at WOT it continues to evacuate where the stock system relies only on IM vacuum. The dual checkvalves open and close as needed so the strongest suction source is always defaulted to.


So, if you intend to keep the car for any length of time, definitely get an Elite E2-X or E2 systems installed.


Ask any questions you may have as so many do not understand proper crankcase evacuation and the PCV system.

you might want to talk to Superman09 before you buy one GM is really putting the screws to this guy... http://www.camaro5.com/forums/showthread.php?t=451361

What would you like them to do? Go put the "shoe-leather" into the Service Manager? Elite didn't do anything wrong. They already stated that they signed the petition. There's not much else they can do if you ask me. It is ultimately up to the Top Brass at GM.

If Elite supplies these cans and a problem ensues as one has, wouldn't they be the best to talk to GM, provide information, fight for the owner who bought his catch can in good faith? From all the information I've read, the catch can doesn't cause an issue creating low oil pressure, it sounds as though there was an internal engine problem.

Communication and support is going to be Superman09's best bet to getting this resolved. The supplier can explain and show documentation that very few of us could, AND if it has their name on it, they are ultimately the expert. Besides, if it was me, I would want Elite's help to get this resolved.

Manufacturers will quickly void warranties and deny claims, they are not immune to fraud. They are also not easy to talk to. When something like this happens, opening lines of communication and being logical will be best for everyone.
1. The owner gets his car fixed - which he should.
2. Elite sells more of their product and now have a reputation for standing behind their customer.
3. GM will see more Camaro sales that would otherwise go to Ford (Mustang for instance) because a LOT of potential buyers read these threads.

I never said Elite did anything wrong, but they are the best placed to help.
I never suggested intimidating or threatening anyone to get it resolved.
If this happens to you, sit back, watch Dr. Phil and hope it all gets better.
There are ALWAYS solutions and I am sure one can be found here.
As for the rest of us, asking questions which could ultimately help someone in our group seems reasonable.

Wow.

Simmer down Hulk. My question was pure sarcasm. I wasn't suggesting somebody go knee-cap the SM at the dealer. I just don't see what they can do here. Yes, they make the can, but it is ultimately up to GM to make this right. Elite can make their case to GM that it is the fault of the oil pump and not the catch can and that is about it. I believe they've already stepped up by supplying useful information here and also signing the petition. If they want to get involved with GM, they will (I'm just not sure it will help ). Wow.

I know there is a resolve here and this is a really good avenue to pursue. Whatever can rectify this situation because right now it looks like David fighting Goliath and there really is no reason for that.

And it's MR. Hulk to you.....

LOL! Let's hope it does get resolved quickly. This particular case is nonsense.

Yes, we have been working with him form the first time he posted and we were made aware of the dealers ridiculous claim. In addition, we have guided him (this is the first time we have ever had a warranty denied in the over 15 years and around 100,000 of proper systems sold, so we take this serious in just supporting the customer and helping in any way possible. We have given him details on how it is impossible for a proper system to cause an oil pump failure (which is not uncommon, just search oil pump failures in LS engines) as they are claiming.


We also provided him with links to the legal defense where the Magnasun/Moss act protects him by Federal law and also the sections pertaining just to an Automotive related example, etc. Further, we have also offered to write a detailed letter by our own engineer with decades of experience in the automotive industry and PCV systems in general covering in detail how the Elite systems work, what they do, and how it would be physically impossible to cause ANY damage or issues to an engine.


Any that have not read his first thread on this (yes, it is long, but we are in it in several places helping). We have also been in contact with the very few other companies that produce proper systems and are "friendly" and not hostile as most competitors are making them aware so if needed, several others can help him as well with letters, etc.


No other manufacturer of catchcans has ever put so much time. effort, and investment into fully understanding every aspect of PCV systems and proper crankcase evacuation than Elite Engineering (just look at all the ineffective systems, or systems that actually cause harm over time to the engines being sold). We also recently made the commitment to be as active as possible in helping forum members with tech help on a variety of automotive related subjects when we see them asking for guidance whether related to our products or not.


There is so much misinformation and crazy harmful products out there related to PCV systems and proper crankcase evacuation the consumer has no idea what is false or misleading VS actual fact, so one only has to follow our posts to see just how far we have come in fully understanding all that is involved VS just "pushing product" as is standard.

We have made this commitment to be the only source anyone needs to look to whether purchasing the correct solution for there specific application from daily driver to 1200 HP Forced Induction Monster, or just wanting to understand and learn. We not only wish the person dealing with this dealer caused nightmare well, but we are here to help in in any way we can.

From what I can remember reading in the original post, this is partially the dealer and someone specifically at GM who had a bad day and is now trying to prove a point and keep their job. What I find ironic is GM performance used them on the ZL1 at the Nurburgring and their 24 hour on track testing. On one of the old ZL1 videos, it clearly show an aluminium catch can installed. I view it as a double standard, and also hypocritical at it's best.

On a forced induction engine catch cans are a must.. I just popped off my intake boot to check it and inside the intake manifold for oil. 4000 miles, 2 track days, found nothing. The boot is dry as is the little clean side hose coming from the oil tank. I tried to take a pic inside the intake but was too dark. I'm sure some vapor gets in but it must be minimal ( in my case anyway ) I have had a catch can on every car I ever owned, so fat I dont see a need yet..
