It gets full very quickly, the guy says it is because of the 3:91 gear and lots of 3000 rpm. Sounds goofy to me, but what do I know ?

This would be "upstream" of the throttle body so it would actually be getting "pull" at WOT... correct? Seems to me I saw one at work with an aftermarket restricted filter and the air inlet was full of oil. Engine found that the breather tube was a good alternative for air thus causeing it to pull excessive oil vapor. Also seems to me that they changed this design of later models.

But, why should there be that much oil vapor floating around. I had the same set up on my Aspen, and never saw much oil in the catch can, even after 17,000 miles. He is saying 1/2 full after 3,000

When I got back the next morning, it was sitting in a significant puddle of oil.

Clean the catch can, change your oil then check it in 1000 miles. See how much is in there. I had a catch can on mine but I took it off. 3oz of oil in 3-4k miles didn't seem like it was worth it to me. If I raced the car regularly maybe I would care more. Wait until the car goes into limp mode in the fast lane of the freeway during rush hour because one of those catch can hoses has a pin hole leak in it. I'd rather burn some oil... DAHIK
