Okay...Im ashamed to ask and I KNOW i've read this in a post just last week and I can’t find it for the life of me. :beatentodeath:

I’m looking for something to supplement my PVC. I don’t want to eliminate it since it’s my DD but the damm thing does leak under boost (yes, it’s OEM). I recall seeing an inline 'check valve' somewhere that works on the same principals of the PCV valve but is supposed to hold back 100+PSI or something crazy like that. Anyone know what I’m talking about?
