I don't see any use for this unless you have a lot of blow by. Won't hurt anything, but no advantage on a well running street car.
Always an advantage to running a catch can. Even a healthy engine will pull oil through the intake. I went with a UPR catch can with a custom bracket so I could keep my engine covers on and easier to service the can. I rather drain the small amount it catches every oil change than gumming up my intake system.
It's a can that collects oil and uses rubber lines. I have not heard or seen how a $200 can does something that the $50 can cannot do. If the $50 dollar machined aluminum can melts or something, then maybe I will look at a more expensive option. My car is a street car, not a race car. Don't need race / aerospace quality gear.
The better catch can will remove almost all liquids from the crankcase blowby gasses before they are returned to the intake manifold, the cheap one will not. That's because the better catch can has a system of chambers and baffles which remove the liquids while the $50 can is simply an empty can. It's what you can't see from the outside that makes the difference.
Take a look at the recent Catch Can Comparison test which measured fluid recovery and flow rates of popular cans. (Google is your friend). MM gen 5+ draft can is currently the best, followed by other familiar brands like Norris Motorsports, Elite, Rx, etc. $50 Chinese junk cans are at the bottom. No surprises.here.
For street driving, not racing, autocross, or other competition driving, these cans are mostly made of nicely machined anodized aluminum, and they all collect oil. Don't see where hundreds of dollars on such a device is worthwhile for my specific needs. I am curious as to where and how to mount these devices of whatever level?
Don't waste your money. Like you, I am not a racer and I don't beat the **** out of my cars. I installed one on my C5. I only drive about 2,500 miles a year.
In 5 years when I emptied it out there was such a small amount of oil --- so I didn't install one in my C6.
In my opinion it's not necessary unless you are frequently doing high RPM's.

I think I'm going to do this. I use the paddles, so I often run at higher revs than the automatic shifting does. As oil in being pulled into the combustion chambers is not good, this should prevent that. However, I am not going to spend unnecessary amounts on a simple oil connection can.

I paid $110 bucks for my in 2009 and it took about 15 minutes to install it.Mounts on the pass side head.Hoses comes with it.
I was at a Corvette car show this weekend. A guy was talking about an oil catch can we installed on his C5 and his C6. Looked on Amazon and say lots of catch cans. Which one to buy, and how do you mount the device in the engine compartment?
Why don't you install the same one you installed on the C5 and C6 cars? Looking at your budget, you could go to a dumpster near you and pull out a piece of cardboard and build it out of that.

I never had a catch can on my C5 (which I no longer owns). I was talking with a guy who had a catch can on his C6. I don't know what brand he had on his car. From past experience, I am not sold on spending $150, $250 or more on a simple can that collects oil.
A simple can might provide good benefit. But, as stated already, it’s what you can’t see that separates the good ones from the cheap ones.
my elite has a really nice set of baffles that help pull oil out of suspension so it doesn’t just go back in the intake.
it also has a screw-on bottom so you can empty it without removing the whole thing.
Some have valves that do the same thing but you have to catch the oil in something.
it also has a mount that saved me a bunch of time in the install. Time is money, so saving me an hour is worth something to me.
your eBay link doesn’t work but the one you linked from Amazon does. That one seems pretty good. It’d be $40 plus making the mount. I got my elite for $100 shipped and didn’t have to make the mount. Plus I know they work well. That cheap one might or might not. If you don’t really have any issues with excessive oil getting into the intake, it’s probably gonna work fine.

I discovered the catch can shown in this post. Saw it on Ebay. It comes with a mount for the Corvette LS engines. Here is the Ebay listing for this can. I will likely pull the trigger on this one.

Yes it looks similar but the UPR one comes with better quality hoses and I'm not sure of the baffle design in the cheaper one. The bracket is the same but it wont fit your engine covers nor is it even designed to be serviced burried in there without removing the whole brake every time, I had to get a long bolt and spacer to make the can sit further out:

"designed to be serviced burried in there"???
So I understand, what does this mean???
Sorry about that, thought the pictures uploaded on the previous post. As you can see, without my custom bracket it would just be a pain to get to and the can would be sitting on coolant lines.

So the bracket that extends from the can attaches to an existing bolt hole? Or, are you attaching to some other thing?

I used the existing hole on the cylinder head with the bolt they supply you, I just placed a small bracket(Metal bracket with 2 holes on top that I had laying around) so the can sits higher and then extended it with a long metal spacer and 6" bolt/nut,

That's the can I bought, modified the bracket to work on my LS2. This is after about 24 pulls on the dyno, and a half tank of gas of street driving:

Looking through Google, there are a ton of ways these cans are plumbed. This one was presented as an option for an SL2. I will be using this configuration. Did you plumb your can, and if so, how did you rig it? I will know specifically how I will do this once the can arrives and I start trial fitting and looking at where the various lines are routed.
Check this thread below where I went through the install. I am still only running the front 2 hoses (Valley port to vacuum port after the throttle body) and did not cap off the valve covers. I will do that later on but for now I am catching most of the oil through the PCV.

My can arrived and I am looking for AN fittings. Question about a couple of things:
How long is the stand off you are using to position the can away from the head?
