The right 6.0 valve cover gasket depends on whether your vehicle has a Ford 6.0L Power Stroke diesel or a GM 6.0L gasoline V8; the parts are not interchangeable. For Ford Super Duty and E-Series applications, compare the FEL-PRO VS 50691 R with the Powerstroke-compatible replacement set. For GM LS and Vortec engines, consider the FEL-PRO VS 50504 R-1 or the listed LS-style gasket sets. Confirm fit by year, model, and engine before ordering.
| Product | Best For | Engine Family |
|---|---|---|
| FEL-PRO VS 50691 R | Ford fitment with stated application coverage | Ford 6.0L diesel |
| Powerstroke Diesel Gasket Set | Ford owners checking replacement part numbers | Ford 6.0L diesel |
| LS 4.8–6.2L Gasket Set | Broad listed LS engine coverage | GM LS V8 |
| MNJWS Gasket Set | GM owners comparing listed Vortec applications | GM Vortec V8 |
| FEL-PRO VS 50504 R-1 | GM buyers seeking a named gasket-set option | GM V8 |
FEL-PRO VS 50691 R For Ford 6.0L
This gasket set is listed for selected Ford Super Duty, Excursion, and E-Series vehicles with application years spanning 2003–2010, depending on model. FEL-PRO says the design is intended to help seal imperfect sealing surfaces, a useful detail for a repair where the mating surfaces may not be ideal.
Best for: Ford owners whose exact vehicle appears in the listed applications and who want a gasket set from a named replacement-parts brand. It is selected for its stated Ford application range and repair-surface design. Check first: The listing requires vehicle fitment verification, including year, engine, and trim. Do not assume every 6.0L Ford application is covered.
Powerstroke Diesel Gasket Set
This set is described for Ford 6.0L V8 turbo diesel applications, including specified 2003–2007 F-250 through F-550 models, 2003–2005 Excursion, and selected E-Series vans through 2010. The listing gives replacement numbers VS50691R, 3C3Z6584BA, and 3C3Z6584AA, which can help buyers compare part references.
Best for: Ford diesel owners who want to cross-check their vehicle against the stated model years and replacement numbers. It was selected as a second Ford-focused option with explicit 6.0L diesel coverage. Check first: The listing advises confirming vehicle compatibility before ordering; verify the exact application rather than relying on “Powerstroke” alone.
LS 4.8L–6.2L V8 Gasket Set
This listing describes coverage for several GM LS engine families, including 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L V8s, with vehicle years stated from 1999 to 2020. It identifies silicone rubber construction and references replacement numbers VS50504R-1 and VS50250A. The listing says it is intended for OE-style or aftermarket valve covers requiring a direct-replacement gasket.
Best for: GM owners with a listed LS engine who want broad engine-family coverage in one listing. It is selected for its explicit 6.0L mention and named engine codes. Check first: The wide application range does not establish fit for every GM 6.0L vehicle; confirm the engine code and gasket requirements.
MNJWS Gasket Set For GM Vortec Engines
The MNJWS listing identifies compatibility with GM Vortec engines from 4.8L to 6.2L and names vehicles such as Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade across stated model years 1999–2020. It references GM part number 12633904 and VS50504R1. The stated purpose is to seal between the valve cover and cylinder head and help prevent oil from leaking out.
Best for: GM Vortec owners whose vehicle and engine match the listing, especially those comparing the provided part numbers. It adds a second aftermarket GM option to compare with the LS-focused listing. Check first: The vehicle list is broad, so verify the exact year, engine, and replacement number before purchase.
FEL-PRO VS 50504 R-1 For GM V8s
This FEL-PRO set is listed for a range of GM vehicles, with the supplied compatibility details naming models from Buick, Cadillac, and Isuzu. The listing also advises checking vehicle information and qualifier notes before purchase. FEL-PRO describes the gasket as designed for repair conditions that may involve imperfect sealing surfaces.
Best for: GM buyers whose exact vehicle and engine are confirmed in the fitment information. It was selected as a branded alternative within the GM gasket group. Check first: The available product details do not fully spell out every 6.0L application, so confirm the specific engine and vehicle fit rather than relying on the product name alone.
Buying Guide: How To Choose A 6.0 Valve Cover Gasket
Does “6.0L” Mean Ford Diesel Or GM Gasoline?
Start by identifying the engine family. Ford’s 6.0L Power Stroke is a turbo diesel; GM’s 6.0L V8 belongs to a different engine family and uses different parts. A gasket listed for one should not be treated as a substitute for the other. Check the vehicle’s engine information and the product’s exact fitment details.
Which Fitment Details Should You Verify?
Match the gasket to the vehicle’s year, make, model, engine, and trim. For GM products, compare engine codes and listed replacement numbers when available. For Ford products, check the stated model-year range and diesel application. If the listing provides fitment notes, read them before ordering.
What Features Matter When Comparing Gaskets?
Prioritize confirmed fitment, the included set’s stated application, and relevant construction or sealing information. The supplied listings mention silicone rubber for one GM set and design considerations for imperfect sealing surfaces for the FEL-PRO options. Do not choose based only on a broad engine-size range.
Frequently Asked Questions
Are Ford and GM 6.0L valve cover gaskets interchangeable?
No. They are different engine families. Select a gasket specifically listed for the vehicle and engine.
How can I confirm a gasket fits my vehicle?
Check year, make, model, engine, and trim against the product fitment details. Also compare any listed replacement part numbers.
What does VS50691R identify?
The Powerstroke listing gives VS50691R as a replacement part number for its Ford 6.0L diesel gasket set. Confirm that number against your vehicle before ordering.
Will every GM 6.0L engine use the same gasket?
Not necessarily. Engine family, vehicle, and valve-cover requirements can affect fitment, so verify the specific application.
