17' GMC 6.2 Supercharged Crank case seal leak

[Tanner Smith]

Hey guys I have a 2017 GMC Sierra 6.2. I have a whipple with long tubes and a dyno tune. I have been having a problem with the crank case seal. It started to leak a month ago. Im guessing from boost in the crank case? The truck has 55,000 miles. The charger has only been on 5,000 miles. I got the seal fixed today, and it started dumping oil again from the same area. Is there anything that I can do to prevent the seal to leak? Or is that how it is since it is boosted? I wouldn't think I would be having oil leak problems so soon even with it supercharged. Any input helps. Thanks

If it's pressurizing the crank case then the PCV system isn't working correctly.

How do I know whats going on with the PCV system? Or what causes the PCV System to not work properly?

I have a mighty mouse catch can. I haven’t installed it yet though.

i would get a vented breather for the valve covers, look on youtube, theres a guy on there from mexico did a vented moroso valve cover system for our trucks.. something is jacked up on your install, not venting the crank case and blowing out seals, contact the installer of the kit
