Yep. I haven't put a gauge on it, but it's definitely significantly higher than the CCV. It's now running in psi range. The CCV runs a vacuum in inches of water column. The high vacuum probably helps with gasket or seal leaks maybe? I don't see how it would help otherwise. From what I'm seeing with the catch can, without it, that oil would be going right back into the intake and getting burned off. Not really cutting oil consumption.

I also can't really give a true assessment of the effectiveness. I went about 7500 to 8000 miles after the change with my normal driving at the time which included freeway driving. I then changed jobs and now have a very short commute and have been doing very little freeway driving. My consumption went way down. But, doing some reading on NewTis I found that oil consumption going down would be expected with around town driving vs freeway driving. When I was doing my previous driving my consumption went down very little with the mod. So, like I said before, I'm not sold on this mod actually working.

I have to get smoged in the next month to renew my registration. We'll see if they call me on it. If they do, I'll be back to the stock system. Then we can see what happens with oil consumption with mostly around town driving. Interesting experiment.
