Been reading about catch cans and believe it would be a useful addition. Did a search and came up with more questions than answers. What do you guys recommend for a DD? I am not interested in cheap ebay junk. Thanks
The proof is in the 600 million cars that do not use them.
Or, keeping it C6 specific, the proof is in the almost 200,000 C6's that DO NOT use them that have suffered NO ill effects whatsoever. Just remember that stat when the "pro" catch can guys come on with their banter.

By the way, you might as well save your money and buy the cheap junk one off of Ebay, because they do the same thing as the shiny expensive ones......NOTHING USEFUL.
not needed, a good true oil seperator can will cut down on oil residue in the intake trac. but my buddy put one on his g8 and after 4 months barely had residue in it. not really needed on a n/a car.
im "PRO" catch can on boosted apps. that get driven hard. but those have the whole evap system removed and proper catch can setup installed. seen some (lil more high mileage) you have to empty 1/2 quart can every 14 days or so of driving. but a N/A dd your money is well spent elsewhere.

You mean PCV system, not evap. Evap system is for fuel vapors.
After seeing how much gunky oil residue had accumulated in my OEM intake manifold and the head ports, I wanted to stop that from happening when I installed my new ported throttle body and ported FAST intake.
Put one together for about 10 bucks and a couple more bucks for the one way valve and the hose lengths. I empty it once a year when I change oil/filter. So far I've found several ounces of gunk that would have ended up in my intake. Makes sense to me.

Question - would you dump this (minus coins of course) into your intake manifold? This is about 5K miles of DD with no real heavy acceleration.
Well, I guess the 200,000 C6's, plus the over 200,000 C5's with the LS motor plus maybe 200,000 other types of vehicles with LS motors driving around with NO problems whatsoever would, so what?
I disagree you dont need one, every oil change I dump about 1/4 cup of oil from my can. My car is a DD, but is also tuned and slightly modified and driven spiritedly. Now maybe the word "needed" is subjective but I wouldnt want ANY oil in my manifold. If you can prevent that with $100 and a diy install then go for it.

I totally agree it isn't needed. Just as an air filter isn't really needed. And you don't really need to change your oil every year or 10K miles. A small mesh screen will do just fine and 5 years or 20K miles, whichever comes first, will work. You can get 200K miles out of these engines without doing those things. But the engine probably runs a little better if you don't pour oil down the intake.
Is it worth $100 and 15 minutes time? I think so but you are certainly free to disagree.

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.
Does installing a catch can affect the warranty? I recently went to the dealer for check engine light and the service writers first question was are there any modifications. He actually questioned the wiring for the battery tender.
