After about 6 months of having my pcv drilled to 7/64 on my 3.6 im getting a check engine light about my idel speed. In drive rpms are at 650 and in park they climb to 1000rpms. I removed the lines comming from the pcv/catch can that go into either side of the intake manifold and plugged the holes. Cleared the code andd it solved the issue, so i know the problem is somewhere in the pcv system. My question is, is it possible to remove the half ass valveless pcv valve and put an actual opening and closing pcv valve in? It seems like my manifold isnt keeping constant pressure? Or what? New gaskets btw upper and lower. Any input is greatly appreciated. Ps custom intake is comming along nicley for those who are wondering
