Finally decided to replace the PCV hose with a smaller ID, $11, sturdy heater hose for a Toyota Pickup, Gates 18423, about 1/2" ID hose. The OEM hose is about 5/8" ID. Will install a new PCV valve and leave the PCV system functioning as intended.

Will be cleaning parts for the rest of the afternoon and hope to install the intake manifold tomorrow.
