Tools You'll Need:
* New PCV valve: Make sure you get the correct replacement part for your specific engine.
* Socket wrench (likely a 7/16" or 1/2" depending on the valve and its mounting)
* Possible extension(s) for better reach
* Ratchet
* Gloves (optional, but recommended)
* Shop rags or paper towels
General Steps:
1. Locate the PCV Valve: This is usually located on the valve cover. The PCV valve itself is a small, typically plastic, valve with a hose attached. On some Ranger engines, it's a more prominent, easily accessible component; on others, it might be tucked away slightly. Look for a hose connected to a valve on the valve cover. Your repair manual will pinpoint it exactly.
2. Disconnect the Hose(s): Carefully disconnect the hose(s) connected to the PCV valve. These hoses are usually attached with a simple push-fit connection; sometimes a slight twist might be needed to disengage them. Be prepared for some oil residue.
3. Remove the PCV Valve: Use your socket wrench and ratchet to remove the PCV valve. It's usually screwed into the valve cover.
4. Install the New PCV Valve: Carefully screw the new PCV valve into the valve cover. Tighten it securely, but don't over-tighten. Again, your repair manual will provide the correct torque specification if available.
5. Reconnect the Hose(s): Carefully reconnect the hose(s) to the new PCV valve. Ensure a snug and secure connection.
6. Check for Leaks: After reconnecting everything, check for any leaks around the new PCV valve and hoses.
Important Considerations:
* Engine Oil: Be prepared for some oil spillage. Have rags or paper towels handy to clean up any mess.
* Accessibility: The valve's location might require some maneuvering and potentially the use of extensions on your socket wrench to reach it comfortably.
* Repair Manual: Using a repair manual specific to your 1987 Ford Ranger and engine is highly recommended. This will provide accurate diagrams and crucial information not found in this general guide.
If you are uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improper installation can lead to engine problems.
