Fel‑Pro Valve Cover Gasket Set for Jeep 4.0L — VS50458R, Cork‑Rubber Complete Kit for Grand Cherokee/Cherokee/Wrangler

Fel‑Pro VS 50458 R is a complete valve cover gasket set engineered to seal the cylinder head on compatible Jeep 4.0L engines, restoring oil containment and preventing leaks.

This Fel‑Pro kit is built for professional-level repairs and DIY maintenance on Jeep Cherokee, Grand Cherokee and Wrangler models that use the 4.0L engine family. The set uses a proprietary cork‑rubber formulation and includes every necessary piece for a valve cover reseal, so you don’t leave the job short parts. Components are designed to conform to imperfect sealing surfaces common on older engines and are validated through on‑vehicle testing to match real‑world conditions.

Will this gasket set fit my Jeep Grand Cherokee?

Compatibility covers a range of Jeep vehicles with the 4.0L engine; always verify fit with your exact year, engine and trim. Fel‑Pro publishes a confirmed fit tool that you should consult before ordering to confirm there are no application notes or exceptions.

• Fits 1996–2001 Jeep Cherokee models equipped with the 4.0L engine.
• Fits 1996–2004 Jeep Grand Cherokee with compatible 4.0L configurations.
• Also compatible with 1997–2006 Jeep Wrangler and TJ models using the 4.0L.
• Check vehicle year, make, model and engine before purchase for precision fit.

How is this gasket set different from a generic valve cover gasket?

Fel‑Pro designs its gaskets specifically for repair environments where sealing surfaces are often worn or slightly uneven. The cork‑rubber material is formulated to remain conformable and resilient, providing a robust seal where a one‑piece generic gasket might fail.

• Proprietary cork‑rubber blends to maintain flexibility and compression over time.
• Engineered for imperfect sealing surfaces typical on used engines.
• Includes all required parts for a complete valve cover reseal unless otherwise noted.
• Tested on-vehicle to validate performance under real driving conditions.

What should I expect during installation and maintenance?

Installation follows standard valve cover gasket replacement steps: remove the valve cover, clean mating surfaces, position the new gaskets and torque fasteners to factory specs. Because the set is designed to handle surface irregularities, you will often avoid additional machining or sealant when correct prep is performed.

• Thoroughly clean old gasket material and oil residue from mating surfaces.
• Use the included gaskets and any supplied parts; torque bolts to OEM specifications.
• Inspect valve cover and head surfaces for warpage or damage before assembly.
• Leak check after warm‑up and a short test drive to confirm proper sealing.

Are there any special notes I should know before ordering?

Fel‑Pro recommends checking the retailer’s “Confirmed Fit” tool for additional fitment notes or qualifiers that may apply to your vehicle. If the fit tool displays an information icon, hover or click to see specific application guidance to avoid ordering the wrong set.

• Always enter full vehicle details (year, make, model, engine and trim) when checking fit.
• Review any qualifier notes shown by the fit confirmation tool before purchase.
• Keep OEM torque values and tightening sequence available during install.
• Consider replacing related seals or grommets while the cover is off to save future labor.

Who is this for: The Fel‑Pro VS 50458 R valve cover gasket set is aimed at technicians and informed DIYers working on Jeep 4.0L engines who want a full, application‑specific gasket kit. It’s particularly useful for vehicles showing oil seepage from the valve cover area, for restorations, or whenever an engine service requires valve cover removal and a reliable reseal is needed.
