I'm wrestling with the possible options of how to properly vent my crankcase with my setup. The motor is a 2006 5.4 3v with a gt35 turbo. Ive tried check valves, catch cans, plugging the driver's side intake nipple and running a breather on the driver's side valve cover nipple. I've tried putting a check valve in line from the driver's side valve cover to prevent boost from pressurising the crankcase (I know I have a pcv valve under the cover but didn't want to rely on it to keep out 8-10 lbs of boost. These are just some of the methods I've tried. Either way I have quite a bit of blow by and all circumstances either lead to oil being spread throughout my engine bay or suspected improper crankcase ventilation. I also suspect I'm getting high crankcase pressure because my oil return for my turbo I suspect is filling up with oil because I've already blown the seals on my first turbo. Any ideas or prior experience with this particular situation would be greatly appreciated.
