Not looking to start any pissing matches but have you guys seen this? I usually watch Bill's videos as they are very informative but this one seems to have caused quite the cluster fock if you read all the comments. Found them pretty entertaining actually. The argument seems to be that the higher rpm is causing excessive pressure on the turbo seals with the CCV mod installed. I have owned several FI sports cars, both blown and turbo including a twin turbo s550.. with all those cars running open system catch cans.. but then again none of those cars were making 30-40lbs of boost so I have no idea if what Bill says is correct or true. It makes sense in theory but I have yet to see or hear anyone else stress this concept. Is Ford's AOS really letting that much oil pass through? Has anyone installed a catch can between the intake and the CCV to check?
