Just had a lengthy conversation with the service manager about this situation.



Takeaways:



1) Dealerships have no authority to revoke a warranty, that gets done at a higher level at GM after the dealership feeds them info after an event.

2) If an engine blows they have to contact GM and GM will want pictures and may even send someone there to check it out. Up to them.

3) Most dealerships are cool about aftermarket parts, so if you have them in your car and go in for an oil change or whatever they aren't going to start crap about a catch can or other mods.

4) If you install a part on your engine that isn't a part of the original design, ie, a catch can, and your engine blows, and you bring the car in under warranty to repair the engine you will almost certainly not be covered under your warranty. They will point to the catch can and say you messed with the oil system and therefor the whole engine isn't covered. They will most likely take pictures and send them to GM for a repair cost that size.
5) If you install a part that is part of the original system, ie, an intake/exhaust, and the engine blows you have a good shot to have it covered under warranty since aftermarket replacement parts are allowed to be installed under FTC law if they are a part of the original system as long as they are not installed incorrectly. The aftermarket part would obviously not be covered.


Point here is make sure you take any aftermarket parts out of your car before towing it in to avoid any issues. I think you would be safe with a catch can as long as you took it out before bringing it in for warranty work.

taking stuff off is still not the answer, you may shit the bed on the side of the road, and towed to dealer, what then?

Still it comes down to the dealership you’re dealing with. If you want to prove them wrong after they tell you that they won’t warranty, get out your checkbook to prove it ....for legal fees.

You would have to tow the car somewhere else, remove the parts, then tow it to the dealer. Which may or may not be a big deal to you.



As I mentioned above, if there's a catch can in your car and your engine goes and you have that catch can in your car and bring it in to repair the engine under warranty work you're not going to be covered unless the dealer and GM miss the fact that you have a catch can somehow. There's no argument to be had. You can't add aftermarket parts to a car that weren't a part of the original design and have the subsystem that part is connected to be covered under warranty anymore. You won't void your warranty though. They just won't cover the repair of that subsystem in the event of a failure.

yeah, that option would be unworkable for me....

A CAI is not part of the original design! I truly think it boils down to GM does not want to pay for anything they do not have to. A catch can would be part of an original design if the engineers could figure out how to get the consumer to empty it. A dry sump would solve most all of these questions. I asked a performance shop owner if he has ever heard of the LT4 engine accumulating oil on the SC on the Corvette side and he said no. He follows forums and stated its not as big of an issue as we are making it on the ZL1 LT4 side. The reason being (most likely)...dry sump system. Ive watched videos of the LT4 on the Vette and it looks like the PCV discharges to the dry sump, therefore eliminating the oil being routed to the SC intake side but rather the sump and being consumed as filtered oil and changed often.

At any rate, mine is installed but I am considering taking it off until I am out of warranty. But then again I am going headers and a tune so I do not know. My tuner is good and will tune it to be safe...but I don't plan on taking the headers off if I have engine issue. At this point its a 50/50 shot.

An air intake is part of the original design. And while a cold air intake is not, my impression was that you would at least have a fighting chance and they would try to investigate whether or not the aftermarket part caused the damage. If you put something that isn't a part of the original design at all, such as a catch can, you'd be shit out of luck.

We will keep this reply short and to the point.


Yes, a breathered can vents to the atmosphere....that is illegal in all 50 States. And also a breathered can defeats a very important function of the OEM PCV system.


Most Catch Cans do little to prevent the issues as they allow more of what enters to pass through then they stop.


This keeps getting completely ignored. We have sold thousands and thousands over the past 15 or so years, and only ONE customer experiencing what the naysayers claim, and that being found to have been a illegal denial, if this was a real issue, don't you think there would be more than that one instance? And why would GM and Ford dealers be installing these on new vehicles for buyers that want them?



And last, no one can explain how using a top tire fuel has an impact on these issues it appears, as it can't. It would have to make contact with the backsides of the valves to help at all, and it doesn't.


NO other company has gone to the lengths we have in actually working with the industry on these issues. From the very costly 2 year study one of the Worlds most respected Lubrication Labs did with our design to the actual affiliated Engineers that tear these down and gather data and proof for all to see.

Well what I get from this post is that catch cans are basically a waste of money. That's the way I read it.

For as smart as you claim to be I can tell you aren't if you cant tell me why Top Their or high quality fuel is important in a direct inject engine. Since you seem to want to push the issue, it is because its a direct inject engine genius and the injectors are directly in the cylinder. So wouldn't it be MORE crucial to keep injectors clean? How do you keep injectors clean? My guess would be to run the best quality fuel you can.

I would suggest instead of coming on a forum looking like an ass for your company you answer some of the emails from people I see cant get answered from your company.

Quit making claims that a dealer cant do something when its been shown they can and what have you done to assist the customer that did have his warranty declined due to the catch can? Nothing but make BS claims on a forum they cant do it. Chevy and their dealers can do whatever they want. Thats why I leave my cars stock.

For a stock LT4 that's been pretty much proven here on these forums.

Does a catch can on an LT4 collect oil?

My spousal unit buys groceries. But I can get fed and live just fine without one.

Let's not confuse function with necessity.

No, it collects "blow-by" which is a combination of unburned fuel and oil. That blow-by, if not scavenged by Positive Crankcase Ventilation (PCV), will condense in the crankcase and over time would result in the breakdown of your engine oil.

I empty my catch can about every 2-3000 miles and consistently get three to four ounces of this condensed fuel/oil vapor. It smells foul and is basically sulphuric acid.
