Yeah definitely not good. Is there that much pressure with this system? I've been trying to research something similar to a blowoff valve to put somewhere to relieve excess pressure buildup to avoid the problem you just mentioned. The MM solutions can with pressure relief valve(if it works) seems like the easiest solution. If not, then placing a pressure relief valve after the catch can on the dirty side so its free of oil. But I'm wondering if the catch can would get backed up with the high pressure going into it or if it would allow enough flow to effectively release the pressure
