RICHWEI Valve Cover Gasket Kit for Ford 4.6L/5.4L V8 (2007–2014) - Complete Seal Set replacing VS50687R

RICHWEI VS50687R is a complete valve cover gasket kit engineered to reseal the cylinder head covers on select 4.6L and 5.4L V8 Ford-family engines from 2007–2014.

If your Ford, Lincoln, Mercury or Avanti V8 is showing oil seepage around the valve covers, this kit provides the gaskets and seals needed to restore a tight, leak-resistant fit. The set replaces factory gasket part numbers VS50687R and VS50433 and fits a range of models including F-150, F-250, F-350, Expedition, Explorer, Mustang, Navigator, Mountaineer, Mark LT and Avanti across the listed years.

Will this gasket set fit my vehicle?

Check engine displacement and model year before ordering: this kit is intended for 4.6L and 5.4L V8 engines in the specified model range. It covers many Ford-family vehicles from 2007 through 2014 but does not work on other engine sizes or model years outside the compatibility list.

• Fits Ford 5.4L V8: F-150 (2007–2010), F-250/F-350 Super Duty (2007–2010), Expedition (2007–2014)
• Fits Ford 4.6L V8: F-150 (2009–2010), Explorer and Explorer Sport Trac (2007–2010), Mustang (2007–2010)
• Lincoln vehicles: Mark LT (2007–2008), Navigator (2007–2014)
• Also compatible with Mercury Mountaineer (2007–2010) and Avanti (2007)

What parts are included and what do they replace?

The kit supplies the major valve cover sealing components necessary for a proper reseal: primary valve cover gaskets plus associated seals and grommets. It is supplied as a direct replacement for part numbers VS50687R and VS50433 so it lines up with OEM reference numbers for these engines.

• Main valve cover gaskets sized for the 4.6L or 5.4L V8 configuration
• Secondary seals and O-rings for oil passages and spark plug wells
• Mounting grommets to secure the covers and prevent leaks
• Designed to match OEM replacement reference numbers for fitment

How will this kit affect engine performance and maintenance?

Replacing deteriorated valve cover gaskets reduces oil leaks that can foul ignition components and drip onto hot engine parts. While gaskets don’t change power output, stopping leaks helps prevent misfires, keeps engine bays cleaner, and reduces the need for frequent oil top-offs or cleanups.

• Prevents oil from contaminating spark plugs and coils
• Makes the engine bay easier to inspect and maintain
• Helps avoid secondary damage from prolonged oil exposure
• Simplifies routine service by restoring OEM sealing surfaces

What should I know before installing this gasket kit?

Prepare proper tools, a clean work area and follow torque specs for the valve cover bolts during reassembly. Inspect mating surfaces for warpage or debris and replace any damaged fasteners to ensure a consistent seal; consider replacing PCV components if they show wear.

• Verify engine size (4.6L or 5.4L) and exact model year prior to purchase
• Clean valve cover and head surfaces thoroughly before fitting new gaskets
• Use correct bolt torque values and tightening sequence to avoid leaks
• Replace worn grommets, bolts, or nearby PCV parts as needed

Who is this for: This RICHWEI gasket set is intended for DIY mechanics and professional technicians working on late‑2000s to early‑2010s Ford-family V8 engines who need a reliable, OEM-referenced replacement. It’s suitable for owners addressing valve cover oil leaks on the listed F-150, Super Duty, Expedition, Explorer, Mustang, Navigator, Mountaineer, Mark LT and Avanti models who want a complete reseal kit for routine repair or preventative maintenance.
