Thanks!

1- The powertrain warranty has been 5/60,000 for years now.
2 -
3- It is not quite a 20% difference. I have a family member who works at the engine plant. Just some minor content has been changed, nothing major. I would say, maybe a 10-12% difference overall.
4- If that worries you, take it off before you go to the dealer, takes 15 min for the Mishimoto one to be removed.

I have both service manuals, the difference is nowhere near 20% between the two. Different in a few ways, yes, but not that much.

I have a bad taste in my mouth regarding the marketing of catch cans on pervious generation port injected engines. No doubt they capture oil, but I've yet to see any evidence of any harmful effects other than a bit of oil pooling in the intake. Therefore, what's the point?

I do not deny the long term effects of oil on the valves in a DI engine. However, blow by is not the only factor involved, oil getting past the valve seals will not be stopped with a catch can. My question was and continues to be, is the factory separation system sufficient to prolong the build up of coke on the valves in the Camaro LT1, and how much additional protection does a catch can actually provide?

Very well formulated question and I am all ears.
I'd add, that the solution is NOT cheap and doesn't seem to eliminate an eventual need for cleaning the valves in high mi cars. Personally, when and if I see my laptimes erode, I will expect for a dealer to clean them as part of warranty. And even if I have to pay for it, it seems to cost circa the same as a can solution. So I echo this above post: what's the point especially if the can can in any way affect warranty coverage of the very motor the solution is supposed to protect?

Ok so GM fibbed about the "20%" yet those motors routinely dyno much higher then their C7 counterparts (same dyno). But let it be
Agree, the warranty in the USA has been reduced. Up here it hasn't. Yay

That is the least they can do considering what you guys gotta pay up there!

please advise proper configuration for my 1LE that isn't tracked or driven more than 3k/yr

Given your intended usage of the car, I hope like heck they will suggested that you spend your $ wiser, such as a couple of nice dinners with your better half, donation to your fave charity, or maybe even a track day Yes, I do hope they will REFUSE to take your money.

Meh, it's $185 for some peace of mind...I seek peace of mind and good health above all else in life.

Agree completely. Hence won't do anything to jeopardize the warranty. If the valves get coked (maybe and/or eventually), assuming I still have her: GM will pay for the cleaning and problem solved. Just a different approach to minimize risk: that's all. Peace

Also, fwiw, I just emptied the Mishimoto piece on my 2016 SS that has 10k miles now. I've emptied it 3 times and it has saved quite a bit of oil from re-entering the intake tract.

I thought I might get one since this will be a high mileage vehicle for me, but I think I'm going to stick with the one the vehicle came equipped with. You know, because chevy has already voided power train warranties over aftermarket catch cans.

Every car will puke some oil. I didn't have a can on my Vette and beat up a proverbial snot out of her for several yrs of track duty. Never an issue. Then got talked into a can which cost me a few hundred bucks all in and of course it was catching oil as ANY can will. But for what actual benefit I am completely unsure of (other than supporting jobs of course). But if it makes ya feel good - why the heck not. And if warranty isn't a priority - then just go for it. Cheers!

Your last question is kinda stupid. No reason to go there. It's just noise.

If a vendor sells a product to "protect" a NEW motor, but a solution voids a warranty, they should at least inform their clients of this trade off.
Especially, if they decide to raise the subject of shortened warranties to start with, as any warranty beats no warranty. As to "noise" a lot of info posted is just that, as it doesn't pertain to Camaro specific motor, nor results from a single test can be applied as representative of thousands LT1 motors produced. If that were the case, I'd never buy my car as Vintage had just lost his motor at COTA. Just like I am yet to see any sludge come out during oil changes. The sky is not falling and if valve cleaning is a requirement for DI motors: so be it as it is not a big deal. Losing warranty is. Note that DI specific can requires drilling, which further complicates this aspect.
Cheers!
