Well after 300 miles after installing my catch can I decided to give it a check. Just like many of you have said I can't believe the amount of oil that gets passed the PCV valve. The can probably caught an ounce or two of oil. Better in the can then in the intake.
dbtx, Is fairly easy and straightforward to install. My only complaint was that nipples on can needed to be turned down from where they where set and holy sh*& where they tight. I thought a was going to snap them off trying to loosen them. I purchased a Billet Tech can, based on what I read on here it seemed to be one of the best ones. The quality of the catch can is great. Their web site has some videos showing a general install.
