Ford Windstar Engine Valve Cover Gasket Replacement Guide (1995-2003)
Fixing that burning oil smell and stopping leaks on your Windstar's engine.
- The rear valve cover gasket on the 3.8L V6 is a very difficult job that requires removing the upper intake manifold.
- Always confirm your engine size (3.0L or 3.8L) before ordering, as the gaskets are different.
- When replacing the rear gasket on a 3.8L, it is smart to also replace the spark plugs, wires, and intake gaskets to save on future labor.
- A leaking valve cover gasket can cause oil to fill the spark plug tubes, leading to engine misfires.
Is Your Windstar's Valve Cover Gasket Failing?
A leaking valve cover gasket is a very common issue on the 1995-2003 Ford Windstar, especially as these vans get older. The constant heat from the engine cooks the original gaskets, causing them to shrink, get hard, and crack. When this happens, oil starts to seep out. Ignoring it can lead to bigger problems, from a messy engine bay to a potential fire hazard.
Key Symptoms of a Leak
- Burning Oil Smell: This is the most common sign. Oil leaks from the valve covers and drips directly onto the hot exhaust manifolds below, creating a distinct and unpleasant burning smell that you might notice inside the van.
- Visible Oil Leaks: You'll see fresh, wet oil on the valve covers or running down the side of the engine. Over time, this oil attracts a lot of dirt and grime, creating a thick, greasy buildup.
- Low Engine Oil: A steady leak will cause your engine oil level to drop over time. If you have to add oil between changes, a bad valve cover gasket could be the reason.
- Smoke from Engine Bay: In cases of a significant leak, you may see smoke coming from under the hood as the oil burns off the hot engine parts.
- Rough Running or Misfires: The gasket set includes seals for the spark plug tubes. When these fail, oil can fill up the spark plug wells, shorting out the spark plug and causing the engine to misfire.
A Note on the 3.8L V6 Engine
If you have the 3.8L V6 engine, which is very common in these vans, the rear valve cover is notoriously difficult to replace. It's located under the upper intake manifold. This means the entire intake manifold has to be removed just to access the rear valve cover. Because of this, the job is much more complex and time-consuming than replacing the front gasket. Many mechanics recommend replacing the spark plugs, wires, and intake manifold gaskets at the same time, since you'll already have everything apart.
Choosing the Right Aftermarket Gasket Set
You don't need to go to a Ford dealer for this part. Quality aftermarket brands offer excellent replacements that often use more modern materials than the original factory gaskets. When shopping, make sure the set you buy is for your specific engine (3.0L or 3.8L) and includes the spark plug tube seals and bolt grommets.
- Reinz (Victor Reinz): Often considered an OEM-quality supplier for many European and domestic cars, Victor Reinz gaskets are well-regarded for their fit and material quality. They are known for using soft, pliable rubber that creates a durable seal. This is a top-tier choice for a long-lasting repair.
- Victor Gaskets: While sometimes associated with Reinz, make sure you are getting a quality product. Generally, they are a reliable choice for many standard repairs.
- Apex: Often seen as a more budget-friendly option, Apex gaskets can provide a good seal for the price. While some forum users have had positive experiences, others prefer to stick with more established names like Reinz or Fel-Pro for critical jobs.

Frequently Asked Questions
Is it hard to replace the valve cover gaskets on a Ford Windstar?
It depends on the engine and which gasket. On the 3.8L V6, the front gasket is straightforward for a DIYer with basic tools. However, the rear gasket is a difficult job rated for experienced mechanics because the upper intake manifold must be removed for access. This adds significant time and complexity.
Should I use sealant (RTV) on the new gaskets?
In most cases, modern rubber gaskets are designed to be installed dry. However, it is standard practice to apply a small dab of oil-resistant RTV sealant at the corners and sharp angles where engine components meet, such as where the timing cover meets the cylinder head, to prevent leaks. Always follow the instructions included with your gasket set or consult a repair manual.
Do I need to replace the bolts or grommets?
Yes, it's highly recommended. The rubber grommets that seal the valve cover bolts get hard and crack just like the main gasket. Quality aftermarket sets include new grommets. Reusing old, hardened grommets is a common cause of continued leaks even after replacing the main gasket.
What else should I replace at the same time?
If you are tackling the rear valve cover gasket on a 3.8L engine, you are already doing most of the labor for several other jobs. It is highly recommended to also replace the spark plugs, spark plug wires, and the upper and lower intake manifold gaskets. This will save you a huge amount of time and money in the future.
