I agree a catch-can isn't needed with a street car but I take exception to saying they do "nothing useful." If you regularly run at sustained WOT (such as on a road course) a catch-can is extremely useful, perhaps even a necessity. Running road courses without a catch-can over time I accumulated large amounts of oil in the breather tube, down into and over the air filter...enough that there was a small puddle of oil beneath the car. 
Installing a catch-can eliminated that problem. After running a weekend at the track I drain-off perhaps a tablespoon of oil from the catch-can. Oil that would have otherwise accumulated elsewhere. I bought the Elite Engineering catch-can...its well made and it comes with all the pieces-parts necessary to install it. Again, IMO a catch-can is not needed on a street car but if you regularly run sustained WOT a catch-can is extremely useful.

I just installed my Elite Engineering can this week. When I removed the OEM hose there was oil in there. I have a DD which I drive with a little spirited. I will check it in 5000 miles and see what is in there.

If your lazy, not mechanically inclined, have no money, or just want to argue . Dont buy one.
If you love your car why not buy one? If you bought a 40k car and dont want to install a 200 dollar mod?
It's an easy install (takes 20 min) , cheap (under 200) dollars. So ask yourself why not?
I worked on turbos before buying my Vette we always put them on to stop the blow by...the Vette has blow by - that is a fact.
Overtime blow by can produce:
Knocking
Pre-detonation
Loss in power
Loss in fuel economy
You may not notice it, you may not ever notice it, you may not care, and the car will probably last forever no problems etc... but you may have loss of power.
For me 200 bucks is worth not having any possiblity of getting blow by and causing loss of power.
The Vette is a performance car, if you focus on performance - get one. If you don't focus on performance dont get one...

Im not a vendor just stating fact. Based on real world application ...not B.S. and a bloated ego.
Just cause you dont want to put one on (due to one of the reasons I listed above ) ...doesnt mean you have to call my post a load of crap... LOL

I dont think NOT having one "hurts" the engine per se, however it doesnt hurt TO have one and gain benefits from it (cleaner manifold no decrease in pwr). Like I mentioned early, "needed" is a subjective word in this post.

He did a baseline dyno and his dyno numbers were higher than they were when he went to that same shop during a dyno days when it had 3500 or 5000 (can't remember exactly) miles on it. I am sure you won't hurt your motor by running one, if you don't believe the techs that say you need oil through the combustion chamber to help keep the valves cool so they don't burn etc. 
I will concede the cleaner manifold, member Keyplyr was big on that, with his shiny fast manifold, didn't want it not shiny inside cause he paid for shiny and he wanted shiny.

Just spoke with local performance shop (vendor) and he says its blow by and will rob you of hp gunking up the manifold. As far as burning valves...no, if you burn up your valves by circumventing that little bit of oil then theres a bigger problem at hand.

I also spoke to many tuners, they say it is a waste of money and they won't sell them.

elite is an excellent company.. I'm NOT saying it is a must. I do think its a good thing to have. Can't hurt anything $200 is chump change when it comes to buying stuff for these cars. I don't regret installing mine. its basically personal preferance, if you want 1 call Steve at elite. He's an excellent Guy to deal with......

Guys, I would not waste anymore time going back and forth on this...nobody is changing anyones mind. It's pointless...and all over a 100$ simple mod.

All I stated was fact...if you feel guilty because your too lazy etc. to put one on...then that is a personal problem you need to deal with.
