How To Install Fel Pro Rubber Valve Cover Gaskets?

Installing a Fel‑Pro rubber valve cover gasket is a straightforward but detail‑sensitive job that can make the difference between a clean, leak‑free engine and an oil‑stained mess. Whether you are a DIY enthusiast or a professional technician, understanding the correct steps, tools, and torque specs will help you get the most out of this Rubber Valve‑based sealing solution. This guide walks you through the entire process, from preparation to final checks, while explaining why each step matters for long‑term reliability.

What Is a Fel‑Pro Rubber Valve Cover Gasket?

A Fel‑Pro rubber valve cover gasket is a precision‑engineered Rubber Valve seal designed to sit between the engine’s valve cover and the cylinder head. It prevents engine oil from leaking out while keeping dirt, moisture, and debris from entering the valve train area. Many Fel‑Pro designs combine rubber with cork, silicone, or other composite materials to balance flexibility, heat resistance, and compression set.

Fel‑Pro gaskets are engineered to work with specific engine families and cover geometries, so choosing the correct Rubber Valve cover gasket for your application is critical. These gaskets are often used in automotive, light‑truck, and some industrial engines where a reliable, service‑friendly seal is required.

Tools and Materials You Will Need

Before you begin, gather the following:

– Socket wrench and appropriate sockets

– Torque wrench (inch‑pounds or foot‑pounds, depending on your engine)

– Clean lint‑free rags

– Brake cleaner or degreaser

– Plastic scraper or gasket‑removal tool

– New Fel‑Pro rubber valve cover gasket

– Replacement valve cover bolts and rubber grommets (if recommended)

– Small amount of RTV silicone (only where specified by the manufacturer)

– Safety glasses and gloves

Having the right tools ensures you can remove the old Rubber Valve seal cleanly and install the new one without damaging the cover or cylinder‑head surfaces.

Step 1: Prepare the Work Area and Engine

Start by parking the vehicle on a level surface and letting the engine cool completely. Hot oil and hot metal increase the risk of burns and can distort measurements when torquing fasteners. Disconnect the negative battery terminal to avoid accidental starts or electrical shorts while working near spark plugs and ignition components.

Remove any components that obstruct access to the valve cover, such as air‑intake ducts, ignition coils, or wiring harnesses. Keep track of fasteners and connectors so you can reassemble everything correctly. A clean, organized workspace reduces the chance of dropping hardware into the engine bay or losing small parts.

Step 2: Remove the Valve Cover

Carefully remove the valve cover bolts or nuts in a crisscross pattern, loosening them gradually rather than removing one completely before the next. This helps prevent warping the cover or cracking the casting. As you remove each fastener, set it aside in a labeled tray or magnetic mat.

Once all bolts are out, gently pry the cover upward using a plastic trim tool. Avoid metal pry bars that can scratch or dent the cover or cylinder head. If the cover is stuck due to old gasket material or RTV, work your way around the perimeter until it releases. Take care not to drop debris into the engine.

Step 3: Remove the Old Rubber Valve Cover Gasket

Inspect the old Rubber Valve cover gasket for signs of oil saturation, cracking, hardening, or compression set. These are common reasons why the seal fails over time. Use a plastic scraper or gasket‑removal tool to remove any remaining gasket material from both the valve cover groove and the cylinder‑head mating surface.

Clean both surfaces thoroughly with brake cleaner or degreaser, then wipe them dry with a lint‑free cloth. Fel‑Pro recommends installing their Rubber Valve cover gaskets clean and dry, without adhesives, unless a small dab of RTV is specifically called out for certain corners or joints. Residual oil, old RTV, or debris can compromise the new seal and lead to leaks.

Step 4: Inspect the Valve Cover and Cylinder Head

Before installing the new Fel‑Pro rubber valve cover gasket, inspect the valve cover for warpage, cracks, or damaged flanges. Stamped‑steel covers can bend if over‑torqued or dropped, which will prevent the Rubber Valve seal from seating evenly. If the cover is badly warped or cracked, replace it rather than trying to reuse it.

Also check the cylinder‑head sealing surface for pitting, corrosion, or casting flash. Light imperfections can often be smoothed with fine sandpaper or a scraper, but deep damage may require professional resurfacing. A flat, smooth mating surface ensures the Rubber Valve cover gasket can compress uniformly and maintain its integrity under thermal cycling.

Step 5: Position the New Fel‑Pro Rubber Valve Cover Gasket

Place the new Fel‑Pro rubber valve cover gasket onto the valve cover, aligning it with the groove and any bolt holes or locator tabs. Many Fel‑Pro designs feature retention features such as tension tabs or molded lips that snap into the cover’s groove. These features help keep the Rubber Valve seal in place during installation and operation.

For stretch‑type or press‑in‑place gaskets, start at one end and press the gasket into the groove using your fingers or a soft tool. Work your way around the cover in small increments, ensuring the gasket seats fully without bunching or overlapping. Avoid sliding your fingers along the gasket, as this can create “leftover” material and uneven compression.

Step 6: Install the Valve Cover

Once the Fel‑Pro rubber valve cover gasket is fully seated, carefully lower the valve cover back onto the cylinder head. Align the bolt holes and any locating dowels or tabs, then start all fasteners by hand. Do not fully tighten any bolt until all are finger‑tight; this prevents misalignment and uneven loading on the Rubber Valve seal.

If your engine uses rubber grommets at the bolt holes, ensure they are in good condition and properly seated. These grommets help distribute clamping force evenly and support the Rubber Valve cover gasket. Replace any hardened, cracked, or missing grommets with new ones.

Step 7: Torque the Valve Cover Bolts

Follow the manufacturer’s specified torque sequence and values for the valve cover bolts. Many engines recommend a crisscross pattern, starting from the center and working outward, to compress the Rubber Valve seal evenly. Typical torque values for Fel‑Pro rubber valve cover gaskets range from about 3 to 5 foot‑pounds, but always refer to your service manual for the exact spec.

Use a torque wrench to avoid over‑tightening, which can crush the Rubber Valve gasket or warp the cover, or under‑tightening, which can leave gaps and cause leaks. If the procedure calls for multiple passes, complete each pass in the recommended sequence before moving to the next.

Step 8: Apply RTV Where Required

Fel‑Pro designs most Rubber Valve cover gaskets to be installed clean and dry, without sealants. However, some cylinder‑head configurations require a small dab of RTV at specific locations, such as cam journal joint corners or areas where other castings meet the valve cover gasket. Only apply RTV where explicitly recommended, and keep the beads small and precise.

Avoid smearing RTV over the entire gasket or mating surface, as this can interfere with the Rubber Valve seal’s ability to compress properly. Excess RTV can also squeeze into the engine and contaminate internal components.

Step 9: Reconnect Components and Check for Leaks

Reinstall any removed components, such as ignition coils, spark plug tubes, or wiring harnesses, and reconnect the negative battery terminal. Start the engine and let it idle while you visually inspect the valve cover area for leaks. Pay close attention to corners, bolt holes, and any areas where RTV was applied.

If you notice any seepage, shut the engine off and allow it to cool before rechecking torque and gasket alignment. In some cases, a brief “break‑in” period of a few hundred miles may be necessary for the Rubber Valve cover gasket to fully settle. After driving, recheck the bolts and tighten them to spec if needed.

Why Proper Installation Matters for Rubber Valve Seals

A Rubber Valve cover gasket may seem like a simple component, but its performance depends heavily on correct installation. Improper cleaning, misalignment, or incorrect torque can all lead to premature failure, oil leaks, and potential engine damage. Fel‑Pro’s engineering focuses on creating Rubber Valve seals that withstand thermal cycling, vibration, and chemical exposure, but these advantages are only realized when the gasket is installed according to the manufacturer’s guidelines.

Using the right tools, following the recommended procedures, and taking the time to inspect and clean all surfaces ensures that your Fel‑Pro rubber valve cover gasket will provide reliable, long‑lasting protection for your engine.

Conclusion

Installing a Fel‑Pro rubber valve cover gasket is a manageable task that can significantly improve your engine’s reliability and cleanliness. By preparing the work area, removing the old Rubber Valve seal carefully, inspecting the cover and cylinder head, and installing the new gasket with the correct torque and sequence, you can achieve a leak‑free seal that lasts. Always refer to the manufacturer’s specifications and use high‑quality replacement parts to get the most out of your Rubber Valve cover gasket.
