| This is the hose that connects the block tube to the PCV valve. The block tube comes out of the crank case on the left side, down below the thermostat housing. The PCV valve is on the bottom side of the intake manifold in the center of the manifold and near the left edge. The hose is a different size on each end. You must use a heat shield to protect this hose from exhaust temps or you will ruin the hose. Last update 04/11 |
