2013 Ford Focus Valve Cover Gasket Replacement
Replacing the valve cover gasket on a 2013 Ford Focus is a vital maintenance task that prevents oil from leaking into spark plug wells and causing engine misfires. This guide provides a detailed, step-by-step walkthrough to help you complete the repair safely and effectively in your own garage.
If you have noticed a burning oil smell or blue smoke drifting from under your hood, your 2.0L engine likely needs attention. Most owners find that a 2013 ford focus valve cover gasket replacement is the most cost-effective way to protect the ignition system and keep the engine bay clean. In this guide, we will break down the tools, parts, and professional techniques required to get the job done right the first time.
Ignoring a leaking gasket can lead to fouled spark plugs and damaged ignition coils, which are much more expensive to replace than a simple rubber seal. We understand that diving into the engine can feel intimidating, but with the right preparation, this is a perfect project for a weekend DIYer. Let’s get your Focus back in top shape and ensure your valvetrain remains protected from the elements.
Why You Need a 2013 ford focus valve cover gasket replacement
The valve cover gasket serves as a critical seal between the top of the cylinder head and the valve cover itself. Over time, the constant heat cycles of the 2.0L GDI engine cause the rubber to become brittle and hard. When the rubber loses its elasticity, it can no longer maintain a tight seal against the aluminum surfaces.
One of the most common signs that you need a 2013 ford focus valve cover gasket replacement is finding oil inside the spark plug tubes. If you pull an ignition coil and see it drenched in oil, the inner seals of the gasket have failed. This oil can short out the spark, leading to a rough idle or a flashing check engine light.
Additionally, external leaks can drip oil onto the hot exhaust manifold. This creates a distinct burning odor and can even pose a minor fire risk if left unaddressed for too long. Keeping the top of your engine dry ensures that your sensors and electrical connectors stay free from corrosive oil saturation.
Essential Tools and Materials
Before you crack open the engine, you need to have your workspace organized. Having the right tools on hand prevents unnecessary trips to the parts store mid-repair. For this specific Ford engine, you will need a mix of standard metric tools and some cleaning supplies.
- 8mm and 10mm sockets: These are the primary sizes for the cover bolts and coil packs.
- Torque wrench: Essential for ensuring the new gasket is compressed evenly without stripping threads.
- Flathead screwdriver: Useful for gently prying electrical connectors and clips.
- Plastic gasket scraper: Never use metal scrapers on aluminum engine heads to avoid deep scratches.
- Brake cleaner and shop towels: To ensure all mating surfaces are perfectly oil-free before installation.
- High-temp RTV silicone: You only need a small amount for the “T-joints” where the timing cover meets the head.
Regarding parts, always purchase a high-quality replacement gasket set. A complete set should include the main outer perimeter gasket and the individual seals for the spark plug wells. Some kits also include new rubber grommets for the valve cover bolts, which we highly recommend replacing.
Step-by-Step 2013 ford focus valve cover gasket replacement Guide
Preparation is the key to a successful repair. Ensure the engine is completely cool to the touch before starting. Working on a hot engine increases the risk of burns and can cause the aluminum valve cover to warp if removed while expanded from heat.
1. Clear the Workspace
Start by removing the plastic engine beauty cover if your Focus is still equipped with one. Simply pull up on the corners to pop it off the mounting studs. This reveals the ignition coils and the top of the valve cover.
Locate the PCV (Positive Crankcase Ventilation) hose connected to the side of the cover. Squeeze the quick-release tabs and pull the hose away. Be careful, as these plastic lines can become extremely fragile with age and may snap if forced.
2. Disconnect Ignition Coils and Wiring
Unplug the electrical connectors from each of the four ignition coils. You may need a small screwdriver to gently lift the locking tabs. Once unplugged, use an 8mm socket to remove the bolts holding the coils in place.
Pull the coils straight up and out of the engine. Inspect the boots for oil saturation. If they are covered in oil, clean them thoroughly with a rag. Set the coils aside in a clean area, keeping them in order for consistent performance.
3. Loosen and Remove Valve Cover Bolts
The valve cover is held down by a series of 10mm bolts around the perimeter and down the center. Loosen these bolts in a crisscross pattern, starting from the outside and working your way in. This prevents the cover from binding or cracking.
Note that some bolts may have brackets attached for wiring harnesses. Keep track of where these brackets go for reassembly. Once all bolts are loose, they should stay “captured” in the cover, or you can pull them out and place them in a magnetic tray.
4. Lifting the Cover
Gently lift the valve cover. If it feels stuck, do not use a metal pry bar. Instead, use a rubber mallet to tap the sides of the cover to break the seal. Once loose, lift it straight up to avoid dropping dirt into the exposed valvetrain.
Immediately cover the exposed camshafts with a clean lint-free towel. This prevents dust, debris, or a stray bolt from falling into the engine. A clean internal environment is absolutely critical for engine longevity during a 2013 ford focus valve cover gasket replacement.
Cleaning and Preparing the Mating Surfaces
The most common reason for a new gasket to leak is poor surface preparation. You must remove every trace of the old gasket and any dried oil residue. Use your plastic scraper to peel away the old rubber from the cylinder head.
Spray a small amount of brake cleaner onto a clean shop towel and wipe the entire mounting surface. The aluminum should look shiny and feel “squeaky clean” to the touch. Pay special attention to the spark plug tube openings, as these are frequent leak points.
On the 2013 Focus engine, there are two spots where the timing chain cover meets the engine block. These “T-joints” have a small seam. Apply a pea-sized dab of high-temp RTV silicone to these seams. This fills the tiny gap that a rubber gasket might miss.
Installing the New Gasket
Flip the valve cover over and pull the old gasket out of its groove. Clean the groove with a cotton swab and brake cleaner to ensure the new seal sits flat. Press the new gasket into the channel, starting at the corners and working toward the middle.
Ensure the gasket is seated firmly and does not “bunch up” in any area. If your kit included new bolt grommets, swap them out now. These grommets provide the downward pressure needed to keep the cover tight against the head.
Carefully lower the cover back onto the engine. Make sure the gasket does not fall out of the groove as you flip it over. Align the bolt holes and hand-thread all the bolts to ensure they are not cross-threaded.
Torque Specs and Final Reassembly
Using your torque wrench is non-negotiable for this job. For the 2013 Ford Focus, the valve cover bolts typically require a light touch—usually around 8 to 10 Newton-meters (roughly 71 to 89 inch-pounds). Check your specific owner’s manual or service guide for the exact figure.
Tighten the bolts in a star pattern, starting from the center bolts and moving outward. This ensures the gasket spreads evenly and creates a perfect seal. Do not over-tighten, as the aluminum threads in the head are very easy to strip.
Once torqued, reinstall the ignition coils and tighten their 8mm bolts. Reconnect the wiring harness and the PCV hose. Double-check that no tools or rags are left in the engine bay. Start the engine and let it idle for a few minutes while inspecting for leaks around the perimeter.
Common Pitfalls to Avoid
One common mistake during a 2013 ford focus valve cover gasket replacement is failing to clean the spark plug wells. If oil is left at the bottom of the well, it can cause the engine to stumble even with a new gasket. Use a long screwdriver and a rag to soak up any residual oil before reinstalling the coils.
Another issue is using too much RTV silicone. A common “more is better” mentality can lead to excess silicone breaking off inside the engine. This stray silicone can clog oil passages or the oil pickup screen, leading to catastrophic engine failure. Use only the small dabs required at the seams.
Finally, ensure the VVT (Variable Valve Timing) solenoid seals are properly aligned if they are part of your gasket design. These seals prevent oil from spraying out near the timing solenoids. If they are pinched during installation, you will have a messy leak almost immediately.
Frequently Asked Questions About 2013 ford focus valve cover gasket replacement
How long does a valve cover gasket replacement take?
For a beginner, the process usually takes between 1.5 to 3 hours. Experienced DIYers can often finish the job in under an hour. Taking your time to clean the surfaces is where most of the time should be spent.
Can I drive with a leaking valve cover gasket?
You can drive for a short period, but it is not recommended. Oil leaking into the spark plug wells will eventually cause engine misfires and potentially damage your catalytic converter. It is best to fix the leak as soon as you notice it.
Do I need to change my oil after replacing the gasket?
It is not strictly necessary, but it is a pro-level practice. During the replacement, small bits of dirt or old gasket might fall into the head. An oil change ensures any contaminants are flushed out of the system quickly.
Why is there oil on my spark plugs?
Oil on the “dry” side of the spark plug (the ceramic part) is almost always caused by a failing valve cover gasket. The inner tube seals have likely hardened and are allowing oil to bypass the cover and pool around the plug.
What happens if I over-tighten the valve cover bolts?
Over-tightening can snap the bolt or, worse, strip the threads in the aluminum cylinder head. If you strip the threads, you will need to use a Heli-Coil kit to repair the engine, which adds significant time and cost to the repair.
Conclusion: Success in the Garage
Performing a 2013 ford focus valve cover gasket replacement is a rewarding way to maintain your vehicle’s health. By taking the time to clean the surfaces properly and using a torque wrench, you ensure a professional-grade repair that will last for years to come.
Remember to keep a close eye on your engine bay for the first few days after the repair to ensure everything remains dry. Taking pride in these DIY repairs not only saves you hundreds of dollars in labor costs but also gives you a deeper understanding of how your Ford Focus operates.
