Tools and Materials:
* New valve cover gasket: Make sure you get the correct one for your engine (2.0L or other).
* Socket set (metric): You'll need various sizes, likely including 8mm, 10mm, and possibly others depending on your specific engine.
* Wrench set (metric): Similar to the sockets, you'll need a range of sizes.
* Ratchet and extensions: To reach those hard-to-reach bolts.
* Screwdriver (Phillips and possibly flathead): For various fasteners.
* Valve cover gasket sealant (optional but recommended): A thin bead of high-temperature RTV silicone sealant will help ensure a good seal.
* Shop rags or paper towels: To clean up oil spills.
* New oil (if necessary): You might spill some during the process.
* Funnel: For refilling the oil.
* Torque wrench (optional but recommended): To tighten bolts to the manufacturer's specifications. Overtightening can damage the valve cover or head.
* Plastic scraper or putty knife: For carefully removing old gasket material.
* Parts cleaner or brake cleaner: For cleaning the valve cover and engine mating surfaces.
Procedure:
1. Disconnect the Negative Battery Terminal: This is crucial to prevent electrical shorts.
2. Locate the Valve Cover: It's the topmost part of the engine, usually made of aluminum or plastic.
3. Remove the Components:
* Disconnect the spark plug wires: Carefully remove the spark plug wires from the spark plugs, noting their order (take a picture or label them).
* Remove the PCV valve hose(s): These are usually connected to the valve cover.
* Remove the breather hose(s): Similar to the PCV hose.
* Remove the bolts holding the valve cover in place: These are usually located around the perimeter of the valve cover. Use the appropriate socket and ratchet to carefully remove each bolt, keeping track of their location and order.
4. Remove the Valve Cover: Once all bolts are out, gently lift the valve cover. There might be some resistance from the old gasket sticking to the engine. Work it free carefully.
5. Clean the Valve Cover and Engine Surface: Thoroughly clean both the valve cover and the engine block mating surface where the gasket sits. Remove all traces of the old gasket material using a plastic scraper, being careful not to scratch the surfaces. Use parts cleaner or brake cleaner and rags. Let it dry completely.
6. Apply Sealant (Optional but Recommended): If using sealant, apply a thin, even bead of high-temperature RTV silicone sealant to the mating surface of the valve cover, following the manufacturer's instructions.
7. Install the New Gasket: Carefully position the new gasket onto the valve cover or engine block (depending on the gasket type). Ensure it's seated correctly.
8. Reinstall the Valve Cover: Carefully lower the valve cover onto the engine block, ensuring the gasket is properly aligned.
9. Reinstall the Bolts: Replace the bolts and tighten them in a star pattern (opposite bolts first, then the ones in between), gradually tightening them to the correct torque specification (consult your repair manual for the proper torque values). Avoid overtightening.
10. Reconnect the Components: Reattach all hoses, spark plug wires, and other components in the reverse order of removal, ensuring everything is securely connected.
11. Check for Leaks: After everything is reconnected, start the engine and let it run for a few minutes. Carefully inspect the valve cover area for any signs of leaks. If you see any leaks, you may need to tighten the bolts or even reseal the gasket.
12. Refill Oil (If Necessary): If you spilled any oil during the process, add the appropriate amount of new oil to the engine.
Important Notes:
* Consult a Repair Manual: A repair manual specific to your 1997 Dodge Neon will provide detailed diagrams, torque specifications, and other valuable information.
* Take Pictures: Before you start, take pictures of the components and their placement to help you during reassembly.
* Patience is Key: This is a relatively straightforward job, but taking your time and paying attention to detail will prevent errors and ensure a successful repair.
* Safety First: Always disconnect the negative battery terminal before starting any work on your vehicle's electrical system.
If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. This guide is for informational purposes only and does not constitute professional automotive advice.
