* Start: The hose will connect to a fitting on the valve cover. This might be a nipple or a short hose already attached to the breather. There's often a small hose leading from inside the valve cover to this fitting.
* End: The other end of the hose connects to a port on one of the intake manifolds (usually near the carburetor). The exact location will depend on the specific manifold design, but it will be near the area where intake air flows into the engine. It may connect to a port directly, or a short pre-attached hose may extend from the port.
Important Note: Due to age, the hose may be brittle and cracked, making it hard to immediately identify. Carefully inspect both valve cover and intake manifold for small ports or hoses that might be connected to a PCV system. A visual inspection of the PCV valve itself (often located near the valve cover) may also give you clues. Referencing a workshop manual specific to your 1984 Honda Prelude with dual carbs is strongly recommended for accurate location and routing.
