Working a slightly OT vehicle, have a quick PCV question. I am installing a set of Mickey Thompson valve covers on a Ford 390. I bought them used, and knockouts were already removed. As it sits, I will have the PCV valve on the passenger rear of the valve cover, while the breather/oil filler will be on the driver side, but that the rear. I know the preferred arrangement is opposite side, opposite end....but will this cause any real issue?
