I second that thought.

As I have posted before (and got an immediate rebuttal from the Elite guy) the intake on my LGX V6 is bone dry.
I checked it literally just last week when I put a new throttle body on it.
Still dry and clean at 46k miles.
And the intake valves were only very slightly coked when I had the manifold off earlier this year while indexing my spark plugs.
So there is nothing to "catch" coming from its crankcase ventilation system and no particular cause for concern, at least in my case.
I expect I may have to do a walnut shell blast at around 100k miles, and will do it myself. No big deal.

The counter argument offered to the factory LGX air/oil separator doing such a good job was that all of that stuff must therefore be returning to inside the engine.
Fair enough. No argument.
But for that and other reasons I change my oil and filter at 3500-4000 miles or at 50% on the oil reminder whichever comes first, not at 13,000+ miles as was shown in the earlier posting. Cheap insurance IHMO.
To me, stretching the oil changes out to whatever the reminder optimistically reports is false economy anyway if one plans to keep their vehicle a long time.

Regardless, adding in a system such as was shown in a prior post is out of the question because I reside in California.
It would not pass the technical inspection during a smog test (I have had vehicles fail tech inspection for much less).
Even if I plugged up the hole that I'd have to drill in the manifold it would be a risk depending upon how anal the inspection tech wanted to be.

So my solution (just one of many possible of course) is more conservative oil change intervals for all of our vehicles.
FWIW.

P.S. I have had catch cans on older vehicles and they definitely did work.
But on the LGX I honestly feel no pressing need.
