As long as you are using a top tier fuel, it's not something you need to worry about, the fuel washes everything down and gets rid of the deposits that form on the valves of direct injected engines.
Also, Catch Cans do NOT STOP oil from getting into the manifold, it only reduces it. So what your doing is simply delaying the inevitable with a DI engine, and that is a tear down and cleaning.
And if a Catch Can is not installed and maintained properly you can end up running lean due to air leaks. They are a waste of money for a non-DI engine.

You don't. Your engine is not Direct Injected, so there's no worry of coking on the valves.

Bill, thanks for your insight and knowledge. Reading "All Corvettes are Red" really helped me appreciate how much went into the C5. I didn't appreciate the difference until I drove 2 C4's in my quest to return to Corvette ownership.
