Fel-Pro Valve Cover Gasket Set for Ford F-250 Super Duty VS 50691R (2003–2007) Cork-Rubber Complete Kit

Fel-Pro VS 50691 R is a complete valve cover gasket set engineered to restore a reliable seal on applicable Ford Super Duty engines without replacing the valve cover.

If your Ford F-250 Super Duty (and related models) is showing oil seepage or dampness around the valve covers, this Fel-Pro gasket kit supplies the vehicle-specific sealing parts designed to fit the original mounting layout. Fel-Pro builds these sets with a cork-rubber compound and a focus on real-world repair conditions so they conform to imperfect mating surfaces and resist common failure modes from heat and vibration.

Which Ford vehicles and years does this gasket set fit?

This Fel-Pro VS 50691 R kit is intended for a range of Ford Super Duty and Excursion/E-Series engines produced in the mid-2000s. Always verify fitment using your vehicle details to ensure compatibility before ordering.

• Fits 2003–2005 Ford Excursion models.
• Compatible with 2003–2007 Ford F-250, F-350, F-450, and F-550 Super Duty trucks.

How does this gasket set handle imperfect sealing surfaces?

Fel-Pro designed the VS 50691 R for practical repair scenarios where mating surfaces may be worn, slightly warped, or have old residue. The cork-rubber formulation provides pliability and compression, allowing the gasket to fill gaps and maintain a strong seal under thermal cycling.

• Proprietary cork-rubber material conforms to surface irregularities.
• Compressible profile maintains contact under vibration and heat.
• Formulated to resist oil soak and maintain sealing properties over time.
• Includes all necessary pieces for a standard valve cover replacement unless noted otherwise.

What comes in the kit and what should I expect during installation?

The kit supplies the valve cover gaskets and associated components required for a typical repair so you won’t need separate rings or seals in most cases. Installation is straightforward for a mechanically inclined owner or technician, but careful surface cleaning and correct torque on fasteners are important to avoid leaks.

• Complete set includes primary valve cover gaskets and any required seals/pieces for the repair.
• Designed to drop into existing valve covers with OE-style fitment points.
• Surface prep—cleaning and inspection—helps ensure the new gaskets seat properly.
• Follow torque specs and sequence to prevent distortion and ensure longevity.

Why choose Fel-Pro instead of a generic gasket?

Fel-Pro focuses on vehicle-specific design and validated performance rather than one-size-fits-all parts. Their components undergo on-vehicle testing to match the sealing needs and installation conditions professional mechanics encounter.

• Vehicle-specific engineering for accurate fitment and sealing.
• Real-world testing and validation on actual vehicles.
• Material selection aimed at durability in engine heat and oil exposure.
• Includes necessary parts to simplify the repair process.

Who is this for: The FEL-PRO VS 50691 R valve cover gasket set is aimed at owners and technicians repairing mid-2000s Ford Super Duty trucks, Excursions, and E-Series vehicles who need a dependable, OEM-matching seal for the valve covers. If you want a repair-grade kit that addresses imperfect sealing surfaces and includes all standard pieces for the job, this Fel-Pro set is built for that use—just confirm fitment for your exact year, engine, and trim before purchasing.
