Jaguar S-Type Engine Valve Cover Gasket Set Replacement Guide (2000-2008)
Stop oil leaks and burning smells by choosing the right valve cover gasket set for your S-Type's V6 or V8 engine.
- A burning oil smell is the most common sign of a failing valve cover gasket on your S-Type.
- Oil in the spark plug wells is a definite indicator that the gasket set needs replacement and can cause engine misfires.
- The V6 engine requires removing the intake manifold for a full replacement, making it a more labor-intensive job than the V8.
- Due to the labor involved, always use a quality aftermarket or OEM gasket set to prevent premature failure and repeat repairs.
Is Your S-Type Leaking Oil? It Could Be the Valve Cover Gaskets
A common issue for the 2000-2008 Jaguar S-Type, affecting both the 3.0L V6 and the 4.2L V8 engines, is a leaking valve cover gasket. This isn't a question of if, but when. The constant heat from the engine causes the original rubber gaskets to harden and lose their seal. The most frequent signs are a burning oil smell in the cabin, visible oil stains on the engine, or even oil dripping onto the hot exhaust manifold, creating smoke.

A significant problem caused by a failed gasket set is oil leaking into the spark plug tubes. This can foul the spark plugs and ignition coils, leading to engine misfires (which may trigger the check engine light), rough running, and reduced performance. If you're replacing your spark plugs and find oil in the wells, the valve cover gasket set is the culprit.

When replacing the valve cover gaskets on your S-Type, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. While OEM parts offer a guaranteed fit, quality aftermarket brands can provide excellent performance, often at a better price. For a critical seal like this, it's wise to avoid the cheapest options and stick with reputable brands.
- Beck Arnley: This brand is often known for repackaging OEM parts, meaning you can get original-quality components without the dealership price tag. They are generally considered a reliable choice.
- Victor Gaskets (Victor Reinz): A well-known name in the gasket industry, Victor Reinz is often an OEM supplier for many European vehicles. However, some mechanics have reported mixed results with fitment on certain applications, so ensuring you have the correct part number for your specific engine is crucial.
- Fel-Pro: Another leading name in aftermarket gaskets, Fel-Pro is known for often improving on the original factory designs to address common failure points. They are a popular and trusted choice among both DIYers and professional mechanics.
Pro Tip: The replacement job for the V6 engine is more involved than for the V8, as it requires removing the intake manifold to access one of the valve covers. Due to the high labor cost, it's highly recommended to use a quality gasket set to avoid having to do the job twice.

Frequently Asked Questions
Are there any recalls for S-Type valve cover gaskets?
No, there have been no specific recalls issued by the NHTSA for engine valve cover gaskets on the 2000-2008 Jaguar S-Type.
Do I need to use sealant with the new gaskets?
Yes, it is common practice to apply a small amount of oil-resistant RTV sealant at specific points, particularly where the timing cover meets the cylinder head, to ensure a complete seal.
Can I replace just the spark plug tube seals?
While sometimes possible, it is highly recommended to replace the entire valve cover gasket set at the same time. The perimeter gasket has been exposed to the same heat and age as the tube seals and is likely to fail soon if not replaced. Given the labor involved, especially on the V6, it's best to do the complete job at once.
What's the difference in replacement difficulty between the V6 and V8?
The V8 engine's valve covers are more directly accessible. On the 3.0L V6, the upper intake manifold must be removed to access the valve cover on the driver's side (Bank 1), making the job significantly more complex and time-consuming.
