Won't hurt to replace or at least clean the PCVValve with Carb\Throttle spray, make sure it rattles....intake manifold it's a little oily...
Not sure if you have the older PCValve with the CoolantOxBow or the newer design with an ElectricHeater?
Consider deleting that PCVCoolantLoop, & it's 5/16" Hoses+Tees, & the Coolant OxBow around the PCVValve;
it's a useless "Rube Goldberg" design that's little more than a source of coolant leaks.
Part on the right side of the IntakeManifoldThroat, I call it the PCVCoolantHeatExchanger;
I ground off those two 5/16"CoolantHoseBarbs & re-installed with a little RTV smear around the ORing at the Manifold.
Be sure to check that 5/8" PCV vacuum hose+tube assembly; the rubber L hoses on the ends are known to crack\leak & cause trouble codes.
