I've been reading articles on these oil catch cans and wanted to get your guys opinions. Is it worth getting and if so what brands are of a good quality.
I have been wondering why no posts about this on the Corvette forum. On the 5th gen camaro forum the battle rages back and forth, it's like politics. I have 2 5th gen SS Camaro's and no catch cans on either but that's just me. Most argue that the newer direct injection engines benefit the most from these. I can tell you Chevrolet did put an oil seperator (catch can) on the 5th gen 1LE model Camaro. I have not kept up with the 6th gen so don't know what they did there. Also don't know if they put them on Z06 vette??
I pulled the intake on my truck and vette, both 6.2L LS3s, when I was upgrading the filters. While I was there, I cracked open the throttle body and looked inside with a flashlight to see pools of oil. Had to use shop cloths on a stick to mop up all of the oil.
Fast forward...
Installed catch cans and check inside every now and then and have found no oil since.
A good size air compressor water seperator works also. Cheaper than a catch can and works just as good. I think the prices for the ones sold can be crazy for what it is. This is not a complicated product. I even saw one made out of a glass canning jar and some pipe.

I'll update the main post with links to sites that sell these products but if anyone out there has installed them please post links to the products you recommend.
Catch cans can be advantageous based on how you drive and your application. The more aggressively you push a 4xx HP high compression motor, the more crankcase blow by you'll have. This CC pressure needs to be scavanged and, per any modern emissions engine, consumed by it and not released to the atmosphere.
Pushing the 4xx HP engine to extreme HP/compression means severe CC pressures will build up. For example, SCed LS engines will not only build up extreme CC pressures, it will also vaporize a certain amount of oil with it. This happens even with stock HP LS engines only moderately pushed.
Here is a pic of the Mighty Mouse catch can (MM is the BEST CC) I set up on a 600HP SCed LS3. The catch can sits between the battery and the fuse box. It is a multiple port anti-siphoned system which is needed for boosted applications.
Suggest you move this Q over to Tech C6 section as you'll get some better technical information.

Glass containers underneath the hood of a performance car ??....interesting.....
Bought one never installed it. I didn't like how it mounted. Maybe if you have a blower or are tracking the car, but for normal spirits driving I don't see the benefit, I do not have a oil consumption problem, never have to add oil between oil changes. I could see potential problems with vacuum leaks. So no is my political position on a stock motor., Bill
I have Elite Engineering cans on both my truck and the car.
Since I have a GS w/the "dry sump" (even though it is more like a damp sump... thanks, GM), I went with the dual can setup that they recommend for the ZR1. One can for the engine blow-by, one for the dry-sump pressure. I DO track the car, so the need for oil capture was there.
I used the Elite E2X for the truck and rigged up a mount using an existing L bracket I had lying around.
I'll give you a definitive answer in two simple steps...
1) I used to get a very noticeable burnt oil type of odor whenever I would accelerate hard (presumably from oil burning inside the hot intake manifold).
2) Installed an Elite Engineering oil catch can and now I never get any type of odor whenever I accelerate hard...not even a trace.
I had a Moroso can on a 2015 Camaro SS 1LE, it captured maybe 2 ounces a month DD. More with track days. I didn't want unspent oil dropping my octane rating

30K mile manual GS (dry sump, hand built). Have two catch cans, one post valley cover and one between the intake and the oil sump (clean oil separator as per EE spec). Dont think ive caught anything noticeable in the separator but the CC between the valley cover and intake definitely has caught quite a bit. Probably about 1/2 a can per oil change or so. Nothing major to damage the engine, for sure, but apparently the oil will cause fuel octane to drop resulting in a timing retarding/power loss. for 150 or so, the CC was worth it.

Oil catch can. Is it worth it?
